curl_setopt

(PHP 4 >= 4.0.2, PHP 5)

curl_setoptcURL 転送用オプションを設定する

説明

bool curl_setopt ( resource $ch , int $option , mixed $value )

指定した cURL セッションハンドルのオプションを設定します。

パラメータ

ch

curl_init() が返す cURL ハンドル。

option

設定したい CURLOPT_XXX オプション。

value

option に設定する値。

value には、 option の以下の値に関して bool 値を指定する必要があります。

オプション value への設定値 注記
CURLOPT_AUTOREFERER TRUE を設定すると、Location: によるリダイレクトを たどる際には自動的に Referer: フィールドをリクエストに 追加します。
CURLOPT_BINARYTRANSFER TRUE を設定すると、CURLOPT_RETURNTRANSFER が使用された場合に出力結果を何も加工せずに返します。
CURLOPT_COOKIESESSION TRUE を設定すると、クッキーの "セッション" を新しく開始します。 以前のセッションで読み込まれていた "セッションクッキー" は無視するよう、 libcurl に指示します。デフォルトでは、それがセッションクッキーであるか どうかにかかわらず libcurl はすべてのクッキーを読み込んで保存します。 セッションクッキーとは、有効期限が指定されておらず "セッション" の間のみ 有効であるクッキーのことです。
CURLOPT_CERTINFO TRUE を設定すると、セキュアな転送時に SSL 証明書の情報を STDERR に出力します。 PHP 5.3.2 以降で使用可能です。これを使うには、CURLOPT_VERBOSE を on にしておかなければなりません。
CURLOPT_CRLF TRUE を設定すると、転送時に Unix 形式の改行を CRLF 形式に変換します。
CURLOPT_DNS_USE_GLOBAL_CACHE TRUE を設定すると、グローバル DNS キャッシュを利用します。 このオプションはスレッドセーフではありません。また、デフォルトで 有効になっています。
CURLOPT_FAILONERROR TRUE を設定すると、HTTP で 400 以上のコードが返ってきた際に 処理失敗と判断し、何もしません。デフォルトでは、コードの値を無視して ページの内容を取得します。
CURLOPT_FILETIME TRUE を設定すると、ドキュメントの更新日時を取得しようと試みます。 この値を取得するには、curl_getinfo()CURLINFO_FILETIME オプションを用います。
CURLOPT_FOLLOWLOCATION TRUE を設定すると、サーバが HTTP ヘッダの一部として送ってくる "Location: " ヘッダの内容をたどります (これは再帰的に行われます。CURLOPT_MAXREDIRS が指定されていない限り、送ってくる "Location: " ヘッダの内容をずっとたどり続けることに注意しましょう)。
CURLOPT_FORBID_REUSE TRUE を設定すると、処理が終了した際に明示的に接続を切断します。 接続を再利用しません。
CURLOPT_FRESH_CONNECT TRUE を設定すると、キャッシュされている接続を利用せずに 新しい接続を確立します。
CURLOPT_FTP_USE_EPRT TRUE を設定すると、FTP のダウンロードに EPRT(および LPRT) を利用します。FALSE の場合は EPRT・LPRT を無効にして PORT を利用します。
CURLOPT_FTP_USE_EPSV TRUE を設定すると、FTP 転送の際にまず EPSV コマンドの利用を 試みます。失敗した場合は PASV を利用します。FALSE を設定すると、 EPSV を無効にします。
CURLOPT_FTP_CREATE_MISSING_DIRS TRUE を設定すると、FTP の操作中にパスが存在しなかったときに ディレクトリを作成します。
CURLOPT_FTPAPPEND TRUE を設定すると、リモートファイルを上書きせずに追記します。
CURLOPT_FTPASCII CURLOPT_TRANSFERTEXT のエイリアスです。
CURLOPT_FTPLISTONLY TRUE を設定すると、FTP でディレクトリ名のみ表示します。
CURLOPT_HEADER TRUE を設定すると、ヘッダの内容も出力します。
CURLINFO_HEADER_OUT TRUE を設定すると、リクエスト文字列を追跡します。 PHP 5.1.3 以降で使用可能です。プレフィックスが CURLINFO_ となっているのは意図的なものです。
CURLOPT_HTTPGET TRUE を設定すると、HTTP のリクエスト形式を GET に戻します。 GET はデフォルト設定なので、リクエスト形式が変更されている 場合にのみ必要となります。
CURLOPT_HTTPPROXYTUNNEL TRUE 指定された HTTP プロキシを介してトンネルに。
CURLOPT_MUTE TRUE を設定すると、cURL 関数に関連する出力を完全に抑えます。
CURLOPT_NETRC TRUE を設定すると、リモートサイトと接続を確立する際に用いる ユーザ名やパスワードを、~/.netrc から取得します。
CURLOPT_NOBODY TRUE を設定すると、出力から本文を削除します。 リクエストメソッドは HEAD となります。これを FALSE に変更してもリクエストメソッドは GET には変わりません。
CURLOPT_NOPROGRESS TRUE を設定すると、cURL 転送の進捗状況表示を無効にします。

注意:

PHP は、このオプションを自動的に TRUE に設定します。 これを変更するのは、デバッグ時のみにすべきです。

CURLOPT_NOSIGNAL TRUE を設定すると、cURL 関数が PHP プロセスに送信するシグナルを 無視します。マルチスレッド SAPI ではデフォルトで on となっており、 そのためタイムアウトオプションもまだ利用されています。 cURL 7.10 で追加されました。
CURLOPT_POST TRUE を設定すると、HTTP POST を行います。POST は、 application/x-www-form-urlencoded 形式で 行われます。これは一般的な HTML のフォームと同じ形式です。
CURLOPT_PUT TRUE を設定すると、HTTP PUT を行います。PUT するファイルは CURLOPT_INFILE および CURLOPT_INFILESIZE で指定されている必要があります。
CURLOPT_RETURNTRANSFER TRUE を設定すると、curl_exec() の返り値を 文字列で返します。通常はデータを直接出力します。
CURLOPT_SSL_VERIFYPEER FALSE を設定すると、cURL はサーバ証明書の検証を行いません。 別の証明書を CURLOPT_CAINFO オプションで 指定するか、CURLOPT_CAPATH オプションで 証明ディレクトリを指定します。 cURL 7.10 以降、デフォルト値は TRUE です。また、 cURL 7.10 以降、デフォルトでインストールされています。
CURLOPT_TRANSFERTEXT TRUE を設定すると、FTP 転送を ASCII モードで行います。 LDAP の場合は、データを HTML ではなくプレーンテキストで取得します。 Windows システムでは STDOUT に対してバイナリモードを設定しないでください。
CURLOPT_UNRESTRICTED_AUTH TRUE を設定すると、(CURLOPT_FOLLOWLOCATION を利用して)場所をたどっていく際にユーザ名とパスワードを送信し続けます。 これは、たとえホスト名が変わっても続けられます。

CURLOPT_BUFFERSIZE 1 回の読み込みに用いるバッファのサイズ。しかしながら、必ず このバッファいっぱいまで読み込まれることを保証するものではありません。 cURL 7.10 で追加されました。
CURLOPT_CLOSEPOLICY CURLCLOSEPOLICY_LEAST_RECENTLY_USED あるいは CURLCLOSEPOLICY_OLDEST です。 他にも 3 つの CURLCLOSEPOLICY_ 定数が存在しますが、 cURL はそれらをまだサポートしていません。
CURLOPT_CONNECTTIMEOUT 接続の試行を待ち続ける秒数。0 は永遠に待ち続けることを意味します。
CURLOPT_CONNECTTIMEOUT_MS 接続の試行を待ち続けるミリ秒数。0 は永遠に待ち続けることを意味します。 システムの標準の名前解決を使うように libcurl をビルドしている場合は、 接続のタイムアウトは秒単位の精度となり、最小のタイムアウトは 1 秒となります。 cURL 7.16.2 で追加されました。PHP 5.2.3 以降で使用可能です。
CURLOPT_DNS_CACHE_TIMEOUT DNS エントリをメモリ内に保持し続ける秒数。デフォルトでは 120(2 分)に設定されています。

CURLOPT_HTTP_VERSION CURL_HTTP_VERSION_NONE (デフォルト。 使用するバージョンを決めるのは cURL にまかせる)、 CURL_HTTP_VERSION_1_0 (HTTP/1.0 を使用する)、 あるいは CURL_HTTP_VERSION_1_1 (HTTP/1.1 を使用する) のいずれかです。
CURLOPT_HTTPAUTH

使用する HTTP 認証方法。以下の中から選びます。 CURLAUTH_BASICCURLAUTH_DIGESTCURLAUTH_GSSNEGOTIATECURLAUTH_NTLMCURLAUTH_ANY および CURLAUTH_ANYSAFE

2 つ以上の方法を組み合わせるには、ビット演算子 |(or) を使用します。このような場合、cURL はサーバがサポートしている方法を 問い合わせたうえで最適な方法を選択します。

CURLAUTH_ANYCURLAUTH_BASIC | CURLAUTH_DIGEST | CURLAUTH_GSSNEGOTIATE | CURLAUTH_NTLM のエイリアスです。

CURLAUTH_ANYSAFECURLAUTH_DIGEST | CURLAUTH_GSSNEGOTIATE | CURLAUTH_NTLM のエイリアスです。

CURLOPT_INFILESIZE ファイルをリモートサイトにアップロードする際のファイルサイズ。 このオプションを指定しても、libcurl がそれ以上のデータを送信するのは止められないことに注意しましょう。 実際に何が送信されるのかは CURLOPT_READFUNCTION に依存します。
CURLOPT_LOW_SPEED_LIMIT 1 秒あたりのバイト数で、転送速度がこれより遅い期間が CURLOPT_LOW_SPEED_TIME 秒以上続いた場合に PHP は転送を終了します。
CURLOPT_LOW_SPEED_TIME 転送速度が CURLOPT_LOW_SPEED_LIMIT より遅い期間がどれだけ続いた場合に転送を異常終了させるかを、 秒単位で指定します。
CURLOPT_MAXCONNECTS 許可される持続的接続の最大数。もしこの値に達した場合、 どの接続を閉じるのかを CURLOPT_CLOSEPOLICY によって決定します。
CURLOPT_MAXREDIRS HTTP のリダイレクト先を追いかける最大値。 CURLOPT_FOLLOWLOCATION とあわせて使用します。
CURLOPT_PORT 接続先のポート番号。
CURLOPT_PROTOCOLS

CURLPROTO_* の値のビットマスク。使用すると、 転送時に libcurl がどのプロトコルを使用するのかに制約を加えます。 さまざまなプロトコルに対応するよう libcurl をビルドしていた場合でも、 これによって特定の転送プロトコルのみを使用するように制限することができます。 デフォルトでは、libcurl がサポートしているすべてのプロトコルの使用を許可します。 CURLOPT_REDIR_PROTOCOLS も参照ください。

使用できるプロトコルオプションは次のとおりです。 CURLPROTO_HTTP, CURLPROTO_HTTPS, CURLPROTO_FTP, CURLPROTO_FTPS, CURLPROTO_SCP, CURLPROTO_SFTP, CURLPROTO_TELNET, CURLPROTO_LDAP, CURLPROTO_LDAPS, CURLPROTO_DICT, CURLPROTO_FILE, CURLPROTO_TFTP, CURLPROTO_ALL

cURL 7.19.4 で追加されました。
CURLOPT_PROXYAUTH プロキシ接続に使用する HTTP 認証の方法。 CURLOPT_HTTPAUTH で説明したのと同じオプションを 指定可能です。プロキシ認証でサポートされているのは、今のところ CURLAUTH_BASIC および CURLAUTH_NTLM のみです。 cURL 7.10.7 で追加されました。
CURLOPT_PROXYPORT プロキシ接続のポート番号。このポート番号は、 CURLOPT_PROXY で指定することも可能です。
CURLOPT_PROXYTYPE CURLPROXY_HTTP(デフォルト)あるいは CURLPROXY_SOCKS5 cURL 7.10 で追加されました。
CURLOPT_REDIR_PROTOCOLS CURLPROTO_* の値のビットマスク。使用すると、 CURLOPT_FOLLOWLOCATION が有効な場合のリダイレクト時の転送に libcurl がどのプロトコルを使用するのかに制約を加えます。これによって、 リダイレクト時に特定の転送プロトコルのみを使用するように制限することができます。 デフォルトでは、libcurl がサポートしているすべてのプロトコルのうち FILE と SCP 以外のすべての使用を許可します。この挙動は 7.19.4 より前のバージョンとは異なります。7.19.4 より前のバージョンでは、 サポートするすべてのプロトコルを無条件に許可していました。 プロトコル定数の値は CURLOPT_PROTOCOLS を参照ください。 cURL 7.19.4 で追加されました。
CURLOPT_RESUME_FROM 転送を途中から再開する場合のバイトオフセット。
CURLOPT_SSL_VERIFYHOST 1 は SSL ピア証明書に一般名が存在するかどうかを調べます。 2 はそれに加え、その名前がホスト名と一致することを検証します。 本番環境では、このオプションの値は常に 2 (デフォルト値) にしておかなければなりません。
CURLOPT_SSLVERSION 使用する SSL のバージョン(2 あるいは 3)。デフォルトでは PHP が自動的に判断しますが、これを手動で設定する必要がある場合もあります。
CURLOPT_TIMECONDITION CURLOPT_TIMEVALUE の扱いを決定します。 CURLOPT_TIMEVALUE で指定した時刻以降に 変更されたページのみを返す場合は CURL_TIMECOND_IFMODSINCE を使用します。 CURLOPT_HEADERTRUE だと仮定すると、 ページが変更されていない場合は "304 Not Modified" ヘッダが返されます。 CURL_TIMECOND_IFUNMODSINCE は反対の意味です。 デフォルトは CURL_TIMECOND_IFMODSINCE です。
CURLOPT_TIMEOUT cURL 関数の実行にかけられる時間の最大値。
CURLOPT_TIMEOUT_MS cURL 関数の実行にかけられる最大のミリ秒数。 システムの標準の名前解決を使うように libcurl をビルドしている場合は、 接続のタイムアウトは秒単位の精度となり、最小のタイムアウトは 1 秒となります。 cURL 7.16.2 で追加されました。PHP 5.2.3 以降で使用可能です。
CURLOPT_TIMEVALUE 1970 年 1 月 1 日からの経過秒数。この値は CURLOPT_TIMECONDITION で使用されます。デフォルトでは CURL_TIMECOND_IFMODSINCE が設定されます。
CURLOPT_MAX_RECV_SPEED_LARGE ダウンロード速度 (単位は「バイト/秒」) の転送中累加平均がこの値を超えると、 転送を一時停止して、平均速度がこのパラメータの値以下に落ちるまで待ちます。 デフォルトは無制限です。 cURL 7.15.5 で追加されました。PHP 5.4.0 以降で使用可能です。
CURLOPT_MAX_SEND_SPEED_LARGE アップロード速度 (単位は「バイト/秒」) の転送中累加平均がこの値を超えると、 転送を一時停止して、平均速度がこのパラメータの値以下に落ちるまで待ちます。 デフォルトは無制限です。 cURL 7.15.5 で追加されました。PHP 5.4.0 以降で使用可能です。

value は、 option パラメータの 以下の値に関して文字列である必要があります。

オプション value への設定値 注記
CURLOPT_CAINFO 接続先を検証するための証明書を保持するファイル名。 これは CURLOPT_SSL_VERIFYPEER を使用する場合に のみ意味を持ちます。 絶対パスで指定しなければなりません。
CURLOPT_CAPATH 複数の証明書ファイルを保持するディレクトリ。このオプションは CURLOPT_SSL_VERIFYPEER とともに使用します。
CURLOPT_COOKIE HTTP リクエストにおける "Cookie: " ヘッダの内容。 クッキーが複数ある場合は、セミコロンとスペースで区切られる (例 "fruit=apple; colour=red") ことに注意しましょう。
CURLOPT_COOKIEFILE クッキーのデータを保持するファイルの名前。クッキーファイルは、 Netscape フォーマットあるいは HTTP ヘッダを単純にファイルにダンプしたものが使用可能です。 名前が空文字列の場合はクッキーを読み込みませんが、クッキーの処理は有効なままです。
CURLOPT_COOKIEJAR ハンドルを閉じる際 (curl_close のコール後など) に、 すべての内部クッキーを保存するファイルの名前。
CURLOPT_CUSTOMREQUEST HTTP リクエストで "GET" あるいは "HEAD" 以外に 使用するカスタムメソッド。これが有用なのは、"DELETE" やその他のあまり知られていない HTTP リクエストを実行する場合です。 使用可能な値は "GET""POST""CONNECT" などです。 HTTP リクエストの内容をすべて指定するわけではありません。つまり、 "GET /index.html HTTP/1.0\r\n\r\n" のような 記述は間違いだということです。

注意:

使用しようとしているメソッドをサーバがサポートしていることを 確かめるまで、これを使用しないでください。

CURLOPT_EGDSOCKET CURLOPT_RANDOM_FILE と似ていますが、 Entropy Gathering Daemon ソケットを使用してファイル名を生成する点が 違います。
CURLOPT_ENCODING "Accept-Encoding: " ヘッダの内容。 これにより、応答のデコードを可能にします。サポートされる エンコーディングは "identity""deflate" および "gzip" です。もし空文字列 "" が指定された場合、 サポートされるエンコーディングをすべて含むヘッダが送信されます。 cURL 7.10 で追加されました。
CURLOPT_FTPPORT FTP で "POST" を使用するための IP アドレスを取得する際に使用される値。 "POST" は、リモートサーバに対してこちらが指定した IP アドレスに 接続するよう指示します。この値に設定できる内容は IP アドレス、ホスト名、 ネットワークインターフェース名(Unix)、あるいは単に '-' を指定する ことでシステムのデフォルト IP アドレスを指定します。
CURLOPT_INTERFACE 使用するネットワークインターフェースの名前。 インターフェース名、IP アドレスあるいはホスト名が指定可能です。
CURLOPT_KRB4LEVEL KRB4(Kerberos 4)セキュリティレベル。以下の値のいずれか (セキュリティの低い順です)が指定可能です。 "clear""safe""confidential""private"。 文字列がこれらのどれでもなかった場合は、 "private" が使用されます。このオプションを NULL にすると KRB4 セキュリティを無効にします。現時点では、KRB4 セキュリティは FTP 転送にのみ使用可能です。
CURLOPT_POSTFIELDS HTTP "POST" で送信するすべてのデータ。 ファイルを送信するには、ファイル名の先頭に @ をつけてフルパスを指定します。ファイルタイプを明示的に指定するには、ファイル名の後に ';type=mimetype' 形式で続けます。 このパラメータは 'para1=val1&para2=val2&...' のように url エンコードされた文字列形式で渡すこともできますし、 フィールド名をキー、データを値とする配列で渡すこともできます。 value が配列の場合、 Content-Type ヘッダには multipart/form-data を設定します。 5.2.0 以降、このオプションに @ プレフィックスつきでファイルを渡したときは value が配列でなければならなくなりました。
CURLOPT_PROXY リクエストを経由させる HTTP プロキシ。
CURLOPT_PROXYUSERPWD プロキシに接続するためのユーザ名とパスワード。 "[username]:[password]" 形式で指定します。
CURLOPT_RANDOM_FILE 使用するファイル名を、SSL の乱数生成器を使用して作成します。
CURLOPT_RANGE 取得するデータの範囲を "X-Y" 形式で指定します。X あるいは Y は省略可能です。 HTTP 転送では、いくつかの範囲をカンマで区切った "X-Y,N-M" のような形式もサポートしています。
CURLOPT_REFERER HTTP リクエストで使用される "Referer: " ヘッダの内容。
CURLOPT_SSL_CIPHER_LIST SSL で使用する暗号のリスト。例えば RC4-SHA および TLSv1 が 使用可能です。
CURLOPT_SSLCERT PEM フォーマットの証明書を含むファイルの名前。
CURLOPT_SSLCERTPASSWD CURLOPT_SSLCERT 証明書を使用する際に必要なパスワード。
CURLOPT_SSLCERTTYPE 証明書の形式。サポートされるフォーマットは "PEM"(デフォルト)、"DER" および "ENG" です。 cURL 7.9.3 で追加されました。

CURLOPT_SSLENGINE_DEFAULT 非対称暗号化で使用する暗号化エンジンの ID 。
CURLOPT_SSLKEY SSL 秘密鍵を含むファイルの名前。
CURLOPT_SSLKEYPASSWD CURLOPT_SSLKEY で指定した SSL 秘密鍵を 使用するために必要なパスワード。

注意:

このオプションには重要なパスワードが含まれます。PHP スクリプトを 安全な状態におくことを忘れないでください。

CURLOPT_SSLKEYTYPE CURLOPT_SSLKEY で指定した SSL 秘密鍵の 形式。サポートされる型は以下のとおりです。 "PEM"(デフォルト)、"DER" および "ENG"
CURLOPT_URL 取得する URL 。curl_init() でセッションを 初期化する際に指定することも可能です。
CURLOPT_USERAGENT HTTP リクエストで使用される "User-Agent: " ヘッダの内容。
CURLOPT_USERPWD 接続に使用するユーザ名とパスワード。 "[username]:[password]" 形式で指定します。

value には、 option の以下の値に関して 配列を指定する必要があります。

I've been stuck when using the CURLOPT_CONNECTTIMEOUT_MS constant. In fact, on my PHP version (5.3.1) it's not a number but rather a string. Same thing for CURLOPT_TIMEOUT_MS.

I got this error: Warning: curl_setopt() expects parameter 2 to be long, string given

If you are experiencing simular problems, you can replace the constant with the actual number or (re)define the constant.

CURLOPT_TIMEOUT_MS should be 155
CURLOPT_CONNECTTIMEOUT_MS should be 156

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT_MS, 2500); // error
curl_setopt($ch, 156, 2500); // problem solved
Adam Monsen 11-Jan-2012 01:36
CURLOPT_POST must be left unset if you want the Content-Type header set to "multipart/form-data" (e.g., when CURLOPT_POSTFIELDS is an array). If you set CURLOPT_POSTFIELDS to an array and have CURLOPT_POST set to TRUE, Content-Length will be -1 and most sane servers will reject the request. If you set CURLOPT_POSTFIELDS to an array and have CURLOPT_POST set to FALSE, cURL will send a GET request.

Sending a post file upload across a squid proxy, the request was rejected by the proxy. In the error page returned it provided among other possible causes:"Expect:" feature is being asked from a HTTP/one.zero.
Solution: Add the option <?php curl_setopt($cl,CURLOPT_HTTPHEADER,array("Expect:")); ?>. This will remove the expect http header.
Steve Kamerman 24-Jun-2011 08:47
If you want cURL to timeout in less than one second, you can use CURLOPT_TIMEOUT_MS, although there is a bug/"feature"  on "Unix-like systems" that causes libcurl to timeout immediately if the value is < 1000 ms with the error "cURL Error (28): Timeout was reached".  The explanation for this behavior is:

"If libcurl is built to use the standard system name resolver, that portion of the transfer will still use full-second resolution for timeouts with a minimum timeout allowed of one second."

What this means to PHP developers is "You can use this function without testing it first, because you can't tell if libcurl is using the standard system name resolver (but you can be pretty sure it is)"

The problem is that on (Li|U)nix, when libcurl uses the standard name resolver, a SIGALRM is raised during name resolution which libcurl thinks is the timeout alarm.

The solution is to disable signals using CURLOPT_NOSIGNAL.  Here's an example script that requests itself causing a 10-second delay so you can test timeouts:

<?php
if (!isset($_GET['foo'])) {
       
// Client
       
$ch = curl_init('http://localhost/test/test_timeout.php?foo=bar');
       
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
       
curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
       
curl_setopt($ch, CURLOPT_TIMEOUT_MS, 200);
       
$data = curl_exec($ch);
       
$curl_errno = curl_errno($ch);
       
$curl_error = curl_error($ch);
       
curl_close($ch);

        if (
$curl_errno > 0) {
                echo
"cURL Error ($curl_errno): $curl_error\n";
        } else {
                echo
"Data received: $data\n";
        }
} else {
       
// Server
       
sleep(10);
        echo
"Done.";
}
?>

When you set ($ch, curlopt_post, 1) , after you have posted your data with curl_exec , you need to set ($ch, curlopt_post, 0), Otherwise all your subsequent requests seems as a post with no postdata and some reverse proxy servers send 500 or 403 error for these case ( access denied or forbidden )!
PHP at RHaworth dot net 02-Apr-2011 11:31
When CURLOPT_FOLLOWLOCATION and CURLOPT_HEADER are both true and redirect/s have happened then the header returned by curl_exec() will contain all the headers in the redirect chain in the order they were encountered.

Force Curl Request To Go To A Particular IP Address

Yes, there is a method of passing an IP address to curl.  Excellent for services with multiple IP addresses and also to take DNS out of the equation for testing/debugging.

<?php
   
function fetch_page($url, $host_ip = NULL)
    {

     
$ch = curl_init();

      if (!
is_null($host_ip))
      {
       
$urldata = parse_url($url);

       
//  Ensure we have the query too, if there is any...
       
if (!empty($urldata['query']))
         
$urldata['path'] .= "?".$urldata['query'];

       
//  Specify the host (name) we want to fetch...
       
$headers = array("Host: ".$urldata['host']);
       
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

       
//  create the connecting url (with the hostname replaced by IP)
       
$url = $urldata['scheme']."://".$host_ip.$urldata['path'];
      }

     
curl_setopt($chCURLOPT_URL, $url);
     
curl_setopt ($ch, CURLOPT_HEADER, 0);
     
curl_setopt($chCURLOPT_RETURNTRANSFER, true);

     
$result = curl_exec ($ch);
     
curl_close ($ch);

      return
$result;
    }
?>

When using CURLOPT_POSTFIELDS with an array as parameter, you have to pay high attention to user input. Unvalidated user input will lead to serious security issues.

<?php

/**
 * test.php:
 */
$ch = curl_init('http://example.com');

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
   
'foo' => $_GET['bar']
));

curl_exec($ch);

Requesting "test.php?bar=@/home/user/test.png" will send "test.png" to example.com.
Make sure you remove the leading "@" from user input.

If your POST data seems to be disappearing (POST data empty, request is being handled by the server as a GET), try rearranging the order of CURLOPT_POSTFIELDS setting with CURLOPT_NOBODY. CURLOPT_POSTFIELDS has to come AFTER CURLOPT_NOBODY setting because if it comes after it wipes out the Content-Type header that tells your URL target that the request is a POST not a GET.

Not sure if this is expected behavior but it certainly isn't documented (except on Stackoverflow.com, which is supremely unhelpful - BTW, guys over on stack overflow... once you've figured out a PHP problem, posting the solution here would save everyone extra search time).

I had problems with the Wikimedia software and sending a POST request where the data was more than 1024 bytes long. I traced this to cURL adding: Expect: 100-continue to the headers.

I added curl_setopt($ch,CURLOPT_HTTPHEADER,array("Expect:")); and that suppresses the Expect line.

Handling redirections with curl if safe_mode or open_basedir is enabled. The function working transparent, no problem with header and returntransfer options. You can handle the max redirection with the optional second argument (the function is set the variable to zero if max redirection exceeded).
Second parameter values:
- maxredirect is null or not set: redirect maximum five time, after raise PHP warning
- maxredirect is greather then zero: no raiser error, but parameter variable set to zero
- maxredirect is less or equal zero: no follow redirections

<?php
function curl_exec_follow(/*resource*/ $ch, /*int*/ &$maxredirect = null) {
   
$mr = $maxredirect === null ? 5 : intval($maxredirect);
    if (
ini_get('open_basedir') == '' && ini_get('safe_mode' == 'Off')) {

FYI... unless you specifically set the user agent, no user agent will be sent in your request as there is no default value like some of the other options.

As others have said, not sending a user agent may cause you to not  get the results that you expected, e.g., 0 byte length content, different content, etc.

A note on the way Curl posts files...

<?php
  curl_setopt
($ch, CURLOPT_POSTFIELDS, array('file' => '@/path/to/file.ext');
?>

will post the FULL PATH of the file in the filename field:

Content-Disposition: form-data; name="file"; filename="/path/to/file.ext"

Whereas typical browser behavior only sends the filename:

Content-Disposition: form-data; name="file"; filename="file.ext"

Workaround:
<?php
  curl_setopt
($ch, CURLOPT_POSTFIELDS, array('file' => '@file.ext');
 
$cwd = getcwd();
 
chdir('/path/to/');
 
$receivedData = curl_exec($ch);
 
chdir($cwd);
?>

In order to reset CURLOPT_HTTPHEADER, set it to array(). The cURL C API says you should set it to NULL, but that doesn’t work in the PHP wrapper.

This function helps to parse netscape cookie file, generated by cURL into cookie array:

<?php
 
function _curl_parse_cookiefile($file) {
   
$aCookies = array();
   
$aLines = file($file);
    foreach(
$aLines as $line){
      if(
'#'==$line{0})
        continue;
     
$arr = explode("\t", $line);
      if(isset(
$arr[5]) && isset($arr[6]))
       
$aCookies[$arr[5]] = $arr[6];
    }
   
    return
$aCookies;
  }

When POSTing with cURL, my POSTs were magically being converted to GETs and I debugged it until finding the issue. I was setting the CURLOPT_MUTE option. Not sure why this conflicts, since the documentation doesn't specify as such. Anyways, if your $_POST is empty, make sure you aren't setting CURLOPT_MUTE.

Cheers!

If you've got problems with connecting througth a proxy using php/apache/xampp. So if you get no result string from the exec function, try enabling the following options in apache.

...\xampp\apache\conf
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

cURL seems to neet this modules.

Sime sites may protect themselves from remote logins by checking which site you came from.

Then you might want to use CURLOPT_REFERER.

<?php

// $url = page to POST data
// $ref_url = tell the server which page you came from (spoofing)
// $login = true will make a clean cookie-file.
// $proxy = proxy data
// $proxystatus = do you use a proxy ? true/false

function
curl_grab_page($url,$ref_url,$data,$login,$proxy,$proxystatus){
    if(
$login == 'true') {
       
$fp = fopen("cookie.txt", "w");
       
fclose($fp);
    }
   
$ch = curl_init();
   
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
   
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
   
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
   
curl_setopt($ch, CURLOPT_TIMEOUT, 40);
   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    if (
$proxystatus == 'true') {
       
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
       
curl_setopt($ch, CURLOPT_PROXY, $proxy);
    }
   
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
   
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

   
curl_setopt($ch, CURLOPT_URL, $url);
   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   
curl_setopt($ch, CURLOPT_REFERER, $ref_url);

   
curl_setopt($ch, CURLOPT_HEADER, TRUE);
   
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
   
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
   
curl_setopt($ch, CURLOPT_POST, TRUE);
   
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
   
ob_start();
    return
curl_exec ($ch); // execute the curl command
   
ob_end_clean();
   
curl_close ($ch);
    unset(
$ch);
}

echo

Be careful when setting the CURLOPT_POSTFIELDS setting using an array. The array used to set the POST fields must only contain scalar values. Multidimentional arrays or objects lacking a __toString implementation will cause Curl to error.

If there is a need to send non-scalar values using a POST request, consider serializing them before transmission.

<?php
$ch
= curl_init('http://host.example.com');

// Data to post
$multiDimensional = array(
  
'name' = 'foo',
  
'data' = array(1,2,3,4),
  
'value' = 'bar'
);

// Will error
curl_setopt($ch, CURLOPT_POSTFIELDS, $multiDimensional);

// Data to post
$postData = array(
 
'name' = 'foo',
 
'data' = serialize(array(1,2,3,4)),
 
'value' = 'bar'
);

// Will not error
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
?>
joeterranova at gmail dot com 26-Jul-2010 09:57
It appears that setting CURLOPT_FILE before setting CURLOPT_RETURNTRANSFER doesn't work, presumably because CURLOPT_FILE depends on CURLOPT_RETURNTRANSFER being set.

So do this:

<?php
curl_setopt
($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FILE, $fp);
?>

not this:

<?php
curl_setopt
($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
?>

CURLOPT_HTTPPROXYTUNNEL means curl will use CONNECT method of the HTTP protocol to make a tunnel through a proxy, which is most likely not the one you want to do.

Some additional notes for curlopt_writefunction. I struggled with this at first because it really isn't documented very well.

When you write a callback function and use it with curlopt_writefunction it will be called MULTIPLE times. Your function MUST return the ammount of data written to it each time. It is very picky about this. Here is a snippet from my code that may help you

<?php
curl_setopt
($this->curl_handle, CURLOPT_WRITEFUNCTION, array($this, "receiveResponse"));

// later on in the class I wrote my receive Response method

private function receiveResponse($curlHandle,$xmldata)
                {
                       
$this->responseString = $xmldata;
                       
$this->responseXML .=  $this->responseString;
                       
$this->length = strlen($xmldata);
                       
$this->size += $this->length;
                        return
$this->length;

                }
?>

Now I did this for a class. If you aren't doing OOP then you will obviously need to modify this for your own use.

CURL calls your script MULTIPLE times because the data will not always be sent all at once. Were talking internet here so its broken up into packets. You need to take your data and concatenate it all together until it is all written. I was about to pull my damn hair out because I would get broken chunks of XML back from the server and at random lengths. I finally figured out what was going on. Hope this helps

Hi,
Anyone who is interested in submitting their information by post to HTTPS site (e.g. payment gateway) where https page needs basic authentication before submitting the information. below code will be helpful.

<?php
$submit_url

$curl = curl_init();

curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC ) ;
curl_setopt($curl, CURLOPT_USERPWD, "username:password");
curl_setopt($curl, CURLOPT_SSLVERSION,3);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($curl, CURLOPT_HEADER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $params );
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($curl, CURLOPT_URL, $submit_url);

$data = split("text/html", curl_exec($curl) );
$temp = split("\r\n", $data[1]) ;

$result = unserialize( $temp[2] ) ;

print_r($result);
curl_close($curl);

For those of you wondering how to specify the content-type for a file uploaded via curl, the syntax is as follows:

<?php

$data
= array('file' => '@/home/user/test.png;type=image/png');

?>

Simply adding a semicolon with the type= at the end.
Note that this has been reported not to work in all versions of PHP and I have done the following tests:

5.2.6 (libcurl 7.18.2) : Does not work
5.2.13 (libcurl 7.20.0) : Works just fine

So it might be worth updating your installation of PHP and/or libcurl if you want to be able to use this syntax

I couldn't find a way to force a curl request to go to a particular IP address, but you can do it with fsockopen:
<?php
    $ip
= '123.45.67.89';
   
$fp = fsockopen($ip, 80, $errno, $errstr, 5);
   
$result = '';
    if (!
$fp) {
        echo
"$errstr ($errno)<br />\n";
    } else {
       
$out = "GET /path/to/the/file.ext HTTP/1.1\r\n";
       
$out .= "Host: www.exampl.com\r\n";
       
$out .= "Connection: Close\r\n\r\n";
       
fwrite($fp, $out);
        while (!
feof($fp)) {
           
$result .= fgets($fp, 128);
        }
       
fclose($fp);
    }
?>
I needed it to test the response from a set of servers behind a load balancer.

If you have turned on conditional gets on a curl handle, and then for a subsequent request, you don't have a good setting for CURLOPT_TIMEVALUE , you can disable If-Modified-Since checking with:

<?php

$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, $foo);
curl_setopt($ch, CURLOPT_TIMEVALUE, filemtime($foo_path));
curl_setopt($ch, CURLOPT_TIMECONDITION, CURLOPT_TIMECOND_IFMODIFIEDSINCE);
curl_exec($ch);
// Reuse same curl handle
curl_setopt($ch, CURLOPT_URL, $bar);
curl_setopt($ch, CURLOPT_TIMEVALUE, null); // don't know mtime
curl_setopt($ch, CURLOPT_TIMECONDITION, 0); // set it to 0, turns it off
curl_exec($ch);

?>

If you need to send deta in a DELETE request, use:

<?php
$request_body
= 'some data';
$ch = curl_init('http://www.example.com');
       
curl_setopt($ch, CURLOPT_POSTFIELDS, $request_body);
       
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
       
curl_setopt($ch, CURLOPT_HEADER, 0);
       
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
       
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
       
$response = curl_exec($ch);
var_dump($response);
?>

If you wish to find the size of the file you are streaming and use it as your header this is how:

<?php

function write_function($curl_resource, $string)
{
    if(
curl_getinfo($curl_resource, CURLINFO_SIZE_DOWNLOAD) <= 2000)
    {
       
header('Expires: 0');
       
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
       
header('Pragma: public');
       
header('Content-Description: File Transfer');
       
header("Content-Transfer-Encoding: binary");
       
header("Content-Type: ".curl_getinfo($curl_resource, CURLINFO_CONTENT_TYPE)."");
       
header("Content-Length: ".curl_getinfo($curl_resource, CURLINFO_CONTENT_LENGTH_DOWNLOAD)."");
    }
   
    print
$string;

    return
mb_strlen($string, '8bit');
}

1440 is the the default number of bytes curl will call the write function (BUFFERSIZE does not affect this, i actually think you can not change this value), so it means the headers are going to be set only one time.

Writefunction must return the exact number of bytes of the string, so you can return a value with mb_strlen.

starosielec at googlemail dot com 20-Feb-2010 12:07
You can use also use object methods as callback functions. This is usefull if your curl ressource is part of an object handling transfers.
Instead of curl_setopt($curl, CURLOPT_WRITEFUNCTION, "curl_handler_recv") you can use array($object, "method") as value for callback options.

For example:

<?php
class downloader {
    private
$curl;

    function
__construct() {
       
$this->curl = curl_init();
       
curl_setopt($this->curl, CURLOPT_WRITEFUNCTION, array($this, "curl_handler_recv"));
    }

     function
curl_handler_recv($res, $data) {
     
//...
    
}
  
//...
}
?>
Ed Cradock 05-Feb-2010 07:47
PUT requests are very simple, just make sure to specify a content-length header and set post fields as a string.

Example:

<?php
function doPut($url, $fields)
{
  
$fields = (is_array($fields)) ? http_build_query($fields) : $fields;

   if(
$ch = curl_init($url))
   {
     
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
     
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
     
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Length: ' . strlen($fields)));
     
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
     
curl_exec($ch);

     
$status = curl_getinfo($ch, CURLINFO_HTTP_CODE);

     
curl_close($ch);

      return (int)
$status;
   }
   else
   {
      return
false;
   }
}

if(
doPut('http://example.com/api/a/b/c', array('foo' => 'bar')) == 200)
  
// do something
else
  
// do something else.
?>

You can grab the request data on the other side with:

<?php
if($_SERVER['REQUEST_METHOD'] == 'PUT')
{
  
parse_str(file_get_contents('php://input'), $requestData);

  
// Array ( [foo] => bar )
  
print_r($requestData);

  
// Do something with data...
}
?>

DELETE  can be done in exactly the same way.

Hello.
During problems with "CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set"
I was looking for solution.
I've found few methods on this page, but none of them was good enough, so I made one.
<?php
function curl_redirect_exec($ch, &$redirects, $curlopt_header = false) {
   
curl_setopt($ch, CURLOPT_HEADER, true);
   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   
$data = curl_exec($ch);
   
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    if (
$http_code == 301 || $http_code == 302) {
        list(
$header) = explode("\r\n\r\n", $data, 2);
       
$matches = array();
       
preg_match('/(Location:|URI:)(.*?)\n/', $header, $matches);
       
$url = trim(array_pop($matches));
       
$url_parsed = parse_url($url);
        if (isset(
$url_parsed)) {
           
curl_setopt($ch, CURLOPT_URL, $url);
           
$redirects++;
            return
curl_redirect_exec($ch, $redirects);
        }
    }
    if (
$curlopt_header)
        return
$data;
    else {
        list(,
$body) = explode("\r\n\r\n", $data, 2);
        return
$body;
    }
}
?>

Main issue in existing functions was lack of information, how many redirects was done.
This one will count it.
First parameter as usual.
Second should be already initialized integer, it will be incremented by number of done redirects.
You can set CURLOPT_HEADER if You need it.

If you change the post array to a string, PHP creates the post data successfully.

As a quick and dirty example of implementing this fix:

<?php

$ch
= curl_init;
$url = 'http://www.example.com';

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);

foreach (
$postData as $var) if (strpos($var, '@') === 0) {
   
$postAsString = true;
}

if (
$postAsString === true) {
   
$str = '';

    foreach (
$postData as $key => $val) {
       
$str .= '&' . $key . '=' . $val;
    }

   
$postData = substr_replace($str, '', 0, 1);
}

curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);

curl_exec($ch);

?>

I've found that setting CURLOPT_HTTPHEADER more than once will clear out any headers you've set previously with CURLOPT_HTTPHEADER.

Consider the following:
<?php
   
# ...

   
curl_setopt($cURL,CURLOPT_HTTPHEADER,array (
       
"Content-Type: text/xml; charset=utf-8",
       
"Expect: 100-continue"
   
));

   
# ... do some other stuff ...

   
curl_setopt($cURL,CURLOPT_HTTPHEADER,array (
       
"Accept: application/json"
   
));

   
# ...
?>

Both the Content-Type and Expect I set will not be in the outgoing headers, but Accept will.

If you get a "failed creating formpost data" upon curl_exec() when POSTing a form, check if one of the field values starts with the @ character.

Took me an hour or so to find out as I wanted to post a @reply tweet to twitter which typically start with @screenname.

There is a function to send POST data in page with five parameters :

$post must be an array
$page is the page where POST datas will be send.

Whats not mentioned in the documentation is that you have to set CURLOPT_COOKIEJAR to a file for the CURL handle to actually use cookies, if it is not set then cookies will not be parsed.
Sylvain R 28-Jul-2009 12:05
When you are using CURLOPT_FILE to download directly into a file you must close the file handler after the curl_close() otherwise the file will be incomplete and you will not be able to use it until the end of the execution of the php process.

<?php

$fh
= fopen('/tmp/foo', 'w');
$ch = curl_init('http://example.com/foo');
curl_setopt($ch, CURLOPT_FILE, $fh);
curl_exec($ch);
curl_close($ch);

# at this point your file is not complete and corrupted

fclose($fh);

# now you can use your file;

read_file('/tmp/foo');

?>

When using CURLOPT_FILE, pass it the file handle that is open for write only (eg fopen('blahblah', 'w+')). If you also open the file for reading (eg fopen('blahblah', 'rw')), curl will fail with error 23.
Victor Jerlin 03-Jul-2009 01:12
Seems like some options not mentioned on this page, but listed on http://curl.haxx.se/libcurl/c/curl_easy_setopt.html is actually supported.

I was happy to see that I could actually use CURLOPT_FTP_CREATE_MISSING_DIRS even from PHP.
xektrum at gmail dot com 02-Jul-2009 06:14
As of php 5.3 CURLOPT_PROGRESSFUNCTION its supported here's how:

<?php

function callback($download_size, $downloaded, $upload_size, $uploaded)
{
   
// do your progress stuff here
}

$ch = curl_init('http://www.example.com');

// This is required to curl give us some progress
// if this is not set to false the progress function never
// gets called
curl_setopt($ch, CURLOPT_NOPROGRESS, false);

// Set up the callback
curl_setopt($ch, CURLOPT_PROGRESSFUNCTION, 'callback');

// Big buffer less progress info/callbacks
// Small buffer more progress info/callbacks
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);

$data = curl_exec($ch);

?>

Hope this help.

I noticed that if you want to get current cookie file after curl_exec() - you need to close current curl handle (like it said in manual), but if you want cookies to be dumped to file after any curl_exec (without curl_close) you can:

<?php
#call it normally
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookiefile");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookiefile");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/');
$result1 = curl_exec($ch);

#and then  make a temp copy
$ch_temp=curl_copy_handle(ch);
curl_close($ch);
$ch=$ch_temp;
?>

Only this way, if you close $ch_temp - cookies wont be dumped.
ericbianchetti at gmail dot com 04-Jun-2009 12:06
if you need to send a SOAP string that is the CURL you must use :

<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, XML_POST_URL);
curl_setopt ($ch, CURLOPT_HTTPHEADER, array('SOAPAction: ""'));   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_POSTFIELDS, XML_PAYLOAD);
curl_setopt($ch, CURLOPT_HEADER, 0);

$output = curl_exec($ch);
?>

Note : Having based my snipet on Chemo demonstration (oscommerce user know who he is), XML_POST_URL and XML_PAYLOAD where defined as constant with define().

The point is : at the opposite of .xml , SOAP must send the header 'SOAPAction: ""' that can be a valid URI, an empty string (that is here) or nothing ('SOAPAction: '). The later case baing not accepted by all server, the second one indicating the target is the URI used to post the SOAP.

When passing CURLOPT_POSTFIELDS a url-encoded string in order to use Content-Type: application/x-www-form-urlencoded, you can pass a string directly:
<?php
curl_setopt
(CURLOPT_POSTFIELDS, 'field1=value&field2=value2');
?>

rather than passing the string in an array, as in fred at themancan dot com's example.
Ariz Jacinto 02-Feb-2009 03:36
if unserialize() returns FALSE on a serialized PHP object due to an extraneous string (e.g. "1") appended at the end of the object, you need to set the ff cURL option:

<?php
curl_setopt
($ch, CURLOPT_RETURNTRANSFER, true);
?>
urkle at outoforder dot cc 28-Jan-2009 03:49
To send a post as a different content-type (ie.. application/json or text/xml) add this setopt call

<?php
curl_setopt
($ch, CURLOPT_HTTPHEADERS,array('Content-Type: application/json'));
?>

[EDIT BY danbrown AT php DOT net: Contains a typofix by 'KdoubleU' on 3-FEB-09.]
fnjordy at gmail dot com 01-Dec-2008 08:28
Note that CURLOPT_RETURNTRANSFER when used with CURLOPT_WRITEFUNCTION has effectively three settings: default, true, and false.

default - callbacks will be called as expected.
true - content will be returned but callback function will not be called.
false - content will be output and callback function will not be called.

Note that CURLOPT_HEADERFUNCTION callbacks are always called.
saidk at phirebranding dot com 19-Nov-2008 10:31
Passing in PHP's $_SESSION into your cURL call:

<?php
session_start
();
$strCookie = 'PHPSESSID=' . $_COOKIE['PHPSESSID'] . '; path=/';
session_write_close();

$curl_handle = curl_init('enter_external_url_here');
curl_setopt( $curl_handle, CURLOPT_COOKIE, $strCookie );
curl_exec($curl_handle);
curl_close($curl_handle);
?>

This worked great for me.  I was calling pages from the same server and needed to keep the $_SESSION variables.  This passes them over.  If you want to test, just print_r($_SESSION);

Enjoy!

This may not be a surprise for many, but I know I bled my eyes out trying to implement this in php. And when I knew it was this simple, I really felt extremely stupid. So I put this just so google will save somebody some time in the future.

PHP NTLM AUTH

Make sure you have the 'curl' extension loaded
now just do...

<?php
curl_setopt
($ch,CURLAUTH_NTLM);
curl_setopt($ch,CURLOPT_USERPWD,"$username:$password");
?>

and just continue to use curl in the ordinary fashion.
OPALA 26-Sep-2008 09:37
To fetch (or submit data to) multiple pages during one session,use this:

<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookiefile");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookiefile");
curl_setopt($ch, CURLOPT_COOKIE, session_name() . '=' . session_id());
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_URL, 'http://example.com/page1.php');
$result1 = curl_exec($ch);

curl_setopt($ch, CURLOPT_URL, 'http://example.com/page2.php');
$result2 = curl_exec($ch);

curl_close($ch);
?>
rkirilow at gmail dot com 16-Sep-2008 10:34
Some of you may noticed that curl is not transferring cookies between sequent calls to a host. This is because you must activate curl`s "cookie parser". That is achieved using an external file like this:
<?php
curl_setopt
(CURLOPT_FILE, '/tmp/cookies_file');
?>
If you don`t need to read any cookies but you still want the "cookie parser" use the same code but with dummy file with no data like '/dev/null', that way curl is storing cookies internaly per curl_handle:
<?php
curl_setopt
(CURLOPT_FILE, '/dev/null');
?>

[EDIT BY danbrown AT php DOT net: In a note dated 26-SEP-08, (adamplumb AT gmail DOT com) offered the following addendum:

[It] should really be CURLOPT_COOKIEFILE.  I was bitten by this issue myself with code that previously worked for logging into a website and posting a form.  However, at some point the code just stopped working, and I eventually found that I needed to set this option to /dev/null for it to work.

George 23-Aug-2008 02:14
If you set CURLOPT_RESUME_FROM to resume the file, and then reuse the same Curl handle to download another file, you must reset the resume status by calling curl_setopt( $ch, CURLOPT_RESUME_FROM, 0 ). It will not reset, and will apply to all subsequent transfers even if the URL is the same.
w dot danford at electronics-software dot com 12-Aug-2008 07:12
Just a small detail I too easily overlooked.
<?php
/*  If you set:  */
curl_setopt ($ch, CURLOPT_POST, 1);
/* then you must have the data: */
curl_setopt ($ch, CURLOPT_POSTFIELDS, $PostData);
?>
I found with only the CURLOPT_POST set (from copy, paste editing of course) cookies were not getting sent with CURLOPT_COOKIE.  Just something subtle to watch out for.
fred at themancan dot com 06-Aug-2008 01:28
To find what encoding a given HTTP POST request uses is easy -- passing an array to CURLOPT_POSTFIELDS results in  multipart/form-data:

<?php
curl_setopt
(CURLOPT_POSTFIELDS, array('field1' => 'value'));
?>

Passing a URL-encoded string will result in application/x-www-form-urlencoded:

<?php
curl_setopt
(CURLOPT_POSTFIELDS, array('field1=value&field2=value2'));
?>

I ran across this when integrating with both a warehouse system and an email system; neither would accept multipart/form-data, but both happily accepted application/x-www-form-urlencoded.
jID 05-Aug-2008 01:56
if you use
<?php
curl_setopt
($ch, CURLOPT_INTERFACE, "XXX.XXX.XXX.XXX");
?>
to specify IP adress for request, sometimes you need to get list of all your IP's.

ifconfig command will output something like:

rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    options=8<VLAN_MTU>
    inet 82.146.XXX.XXX netmask 0xffffffff broadcast 82.146.XXX.XXX
    inet 78.24.XXX.XXX netmask 0xffffffff broadcast 78.24.XXX.XXX
    inet 82.146.XXX.XXX netmask 0xffffffff broadcast 82.146.XXX.XXX
    inet 82.146.XXX.XXX netmask 0xffffffff broadcast 82.146.XXX.XXX
    inet 82.146.XXX.XXX netmask 0xffffffff broadcast 82.146.XXX.XXX
    inet 78.24.XXX.XXX netmask 0xffffffff broadcast 78.24.XXX.XXX
    inet 78.24.XXX.XXX netmask 0xffffffff broadcast 78.24.XXX.XXX
    ether XX:XX:XX:XX:XX:XX
    media: Ethernet autoselect (100baseTX <full-duplex>)
    status: active
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
    Opened by PID 564
tun1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
    Opened by PID 565
    Opened by PID 565

My solution for FreeBSD 6 and PHP 5 was:
<?php
  ob_start
();
 
$ips=array();
 
$ifconfig=system("ifconfig");
  echo
$ifconfig;
 
$ifconfig=ob_get_contents();
 
ob_end_clean();
 
$ifconfig=explode(chr(10), $ifconfig);
  for (
$i=0; $i<count($ifconfig); $i++) {
   
$t=explode(" ", $ifconfig[$i]);
    if (
$t[0]=="\tinet") {
     
array_push($ips, $t[1]);
    }    
  }
  for (
$i=0; $i<count($ips); $i++) {
    echo
$ips[$i]."\n";
  }
?>

You will get list of IP adresses in $ips array, like:
82.146.XXX.XXX
78.24.XXX.XXX
82.146.XXX.XXX
82.146.XXX.XXX
82.146.XXX.XXX
78.24.XXX.XXX
78.24.XXX.XXX

If you want to connect to a server which requires that you identify yourself with a certificate, use following code. Your certificate and servers certificate are signed by an authority whose certificate is in ca.ctr.

<?php
curl_setopt
($ch, CURLOPT_VERBOSE, '1');
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, '1');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, '1');
curl_setopt($ch, CURLOPT_CAINFOgetcwd().'/cert/ca.crt');
curl_setopt($ch, CURLOPT_SSLCERT, getcwd().'/cert/mycert.pem');
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, 'password');
?>

If your original certificate is in .pfx format, you have to convert it to .pem using following commands
# openssl pkcs12 -in mycert.pfx -out mycert.key
# openssl rsa -in mycert.key -out mycert.pem
# openssl x509 -in mycert.key >> mycert.pem

Although CURLOPT_CLOSEPOLICY and the applicable choices are valid constants, setting this option with curl_setopt() always returns false. A quick google search suggests the option is deprecated and/or never worked.
Salil Kothadia 19-Jun-2008 06:02
In PHP5, for the "CURLOPT_POSTFIELDS" option, we can use:

<?php
$ch
= curl_init($URI);
$Post = http_build_query($PostData);
curl_setopt($ch, CURLOPT_POSTFIELDS, $Post);
$Output = curl_exec($ch);
curl_close($ch);
?>
sgamon at yahoo dot com 10-Apr-2008 02:55
If you are doing a POST, and the content length is 1,025 or greater, then curl exploits a feature of http 1.1: 100 (Continue) Status.

See http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.2.3

* it adds a header, "Expect: 100-continue". 
* it then sends the request head, waits for a 100 response code, then sends the content

Not all web servers support this though.  Various errors are returned depending on the server.  If this happens to you, suppress the "Expect" header with this command:

<?php
curl_setopt
($ch, CURLOPT_HTTPHEADER, array('Expect:'));
?>

See http://www.gnegg.ch/2007/02/the-return-of-except-100-continue/
john factorial 04-Apr-2008 05:22
Clarification for the CURLOPT_NOBODY option: by excluding the body from your request, you're effectively making a HEAD request. Use the CURLOPT_NOBODY option to return only the headers in the remote response.

Example:

<?php
function check_url($url) {
   
$c = curl_init();
   
curl_setopt($c, CURLOPT_URL, $url);
   
curl_setopt($c, CURLOPT_HEADER, 1); // get the header
   
curl_setopt($c, CURLOPT_NOBODY, 1); // and *only* get the header
   
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1); // get the response as a string from curl_exec(), rather than echoing it
   
curl_setopt($c, CURLOPT_FRESH_CONNECT, 1); // don't use a cached version of the url
   
if (!curl_exec($c)) { return false; }

   
$httpcode = curl_getinfo($c, CURLINFO_HTTP_CODE);
    return (
$httpcode < 400);
}
?>

if you would like to send xml request to a server (lets say, making a soap proxy),
you have to set

<?php
curl_setopt
($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/xml"));
?>

makesure you watch for cache issue:
the below code will prevent cache...

<?php
curl_setopt
($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_FRESH_CONNECT, 1);
?>

hope it helps ;)
mavook at gmail dot com 16-Feb-2008 07:26
If you try to upload file to a server, you need do CURLOPT_POST first and then fill CURLOPT_POSTFIELDS.

<?php
curl_setopt
($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);
// ^^ This will post multipart/form-data

FYI,

Anyone trying to connect to .NET with CURL to send a simple XML post, pay attention to the following. This will save you hours! There is a previous note that I saw either on this page, or somewhere else on this site that explains the correct way to specify the header option is to create an array, then reference the array from the CURLOPT.

ie.  Do something like this:

<?php
// Req. HTTP Header Values
 
$header[] = "Content-type: text/xml";

// Target URL
 
$sendTo = "http://www.example.com";

// Post Data
 
$post = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<root>\n....etc, etc,";

// Create CURL Connection
 
$ch = curl_init();
 
curl_setopt($ch, CURLOPT_USERAGENT, 'XtraDoh xAgent');
 
curl_setopt($ch, CURLOPT_URL, $sendTo);
 
curl_setopt($ch, CURLOPT_TIMEOUT, 900);
 
curl_setopt($ch, CURLOPT_CONNECTIONTIMEOUT, 30);
 
curl_setopt($ch, CURLOPT_FAILONERROR, false);
 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
 
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
 
curl_setopt($ch, CURLOPT_POST, true);
 
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
?>

Notice the HTTPHEADER, $header above. I have not been able to get .NET to properly read the HTTP header as specified (in this case as text/xml) when using the following:

<?php
curl_setopt
($ch, CURLOPT_HTTPHEADER, array('Content-Type'=>'text/xml'));
?>

Although this may work when working with other PHP, IIS, or even PHP, Apache, it does not (at least in my experience) work with .NET, IIS.
andrabr at gmail dot com 20-Aug-2007 11:03
This is very clear in hindsight, but it still cost me several hours:

<?php curl_setopt($session, CURLOPT_HTTPPROXYTUNNEL, 1); ?>

means that you will tunnel THROUGH the proxy, as in "your communications will go as if the proxy is NOT THERE".

Why do you care? - Well, if you are trying to use, say, Paros, to debug HTTP between your cURL and the server, with CURLOPT_HTTPPROXYTUNNEL set to TRUE Paros will not see or log your traffic thus defeating the purpose and driving you nuts.

There are other cases, of course, where this option is extremely useful...
michael sky 06-Jul-2007 12:09
if you are trying to connect to 'https://...' and after that want to work with POST data - that's the way:

<?php
$curl
= curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_COOKIEFILE, "cookiefile");
curl_setopt($curl, CURLOPT_COOKIEJAR, "cookiefile"); # SAME cookiefile

Two things that I noted, one of which has been mentioned earlier, if you are connecting to an SSL site (https) and don't have the appropriate certificate, don't forget to set CURLOPT_SSL_VERIFYPEER as "false"... it's set to "true" by default. Scratched my head over 2 hours to figure this one out as I had a machine with an older version installed and everything worked fine without using this option on that one - but failed on other machines with newer versions.

Second very important thing, I've never had my scripts work (tried on various machines, multiple platforms) with a Relative path to a COOKIEJAR or COOKIEFILE. In my experience I HAVE to specify the absolute path and not the relative path.

Small script I wrote to connect to a page, gather all cookies into a jar, connect to another page to login, taking the cookiejar with you for authentication:

<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, "/Library/WebServer/Documents/tmp/cookieFileName");
curl_setopt($ch, CURLOPT_URL,"https://www.example.com/myaccount/start.asp");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
ob_start();      // Prevent output
curl_exec ($ch);
ob_end_clean();  // End preventing output
curl_close ($ch);
unset(
$ch);

$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "field1=".$f1."&field2=".$f2."&SomeFlag=True");
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_COOKIEFILE, "/Library/WebServer/Documents/tmp/cookieFileName");
curl_setopt($ch, CURLOPT_URL,"https://www.example.com/myaccount/Login.asp");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$result = curl_exec ($ch);
curl_close ($ch);
?>

If you are getting the following error:

SSL: certificate subject name 'example.com' does not match target host name 'example.net'

Then you can set the following option to get around it:

<?php curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); ?>

Please note that the CURLOPT_INTERFACE setting only accepts IP addresses and hostnames of the local machine. It is not meant to send a URL to a specific IP address.

In case you wonder how come, that cookies don't work under Windows, I've googled for some answers, and here is the result: Under WIN you need to input absolute path of the cookie file.

This piece of code solves it:

<?php

if ($cookies != '')
    {
    if (
substr(PHP_OS, 0, 3) == 'WIN')
        {
$cookies = str_replace('\\','/', getcwd().'/'.$cookies);}
   
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookies);
   
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookies);
    }

?>

curl will sometimes return an "Empty reply from server" error if you don't send a User-Agent string.  Use the CURLOPT_USERAGENT option.

Options not included in the above, but that work (Taken from the libcurl.a C documentation)

CURLOPT_FTP_SSL

Pass a long using one of the values from below, to make libcurl use your desired level of SSL for the ftp transfer. (Added in 7.11.0)

CURLFTPSSL_NONE

Don't attempt to use SSL.

CURLFTPSSL_TRY

Try using SSL, proceed as normal otherwise.

CURLFTPSSL_CONTROL

Require SSL for the control connection or fail with CURLE_FTP_SSL_FAILED.

CURLFTPSSL_ALL

Require SSL for all communication or fail with CURLE_FTP_SSL_FAILED.

Seems that CURLOPT_RETURNTRANSFER Option set to TRUE, returns a "1" when the transaction returns a blank page.

I think is for eliminate the FALSE to can be with a blank page as return

How to get rid of response after POST: just add callback function for returned data (CURLOPT_WRITEFUNCTION) and make this function empty.

<?php

}
curl_setopt($ch, CURLOPT_WRITEFUNCTION, 'curlHeaderCallback');

I was having problems with Authorize.net and the SSL cert matching even after adding:

<?php
curl_setopt
($ch, CURLOPT_SSL_VERIFYPEER, 0);
?>

What I found after a lot of stumbling was I needed to set VERIFYHOST to FALSE.  So if you are still have a problem with Authorize.NET SSL and cURL add this:

<?php
curl_setopt
($ch, CURLOPT_SSL_VERIFYHOST, 0);
?>
pyroevi at yahoo dot com 22-Nov-2006 07:33
I was working on using php to interface with an authorize.net gateway, and I ran into a problem with certificates using curl to talk the https:// url.

curl_error() told me "SSL certificate problem, verify that the CA cert is OK."

I googled it and found the same "solution" over and over again: bypass verification by adding this line after curl_init():

<?php
curl_setopt
($connection, CURLOPT_SSL_VERIFYPEER, false);
?>

This worked great, but I was required to verify, so here's what I did. Add the following lines:

<?php
curl_setopt
($connection, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($connection, CURLOPT_CAINFO, "path:/ca-bundle.crt");
?>

with "path:/ca-bundle.crt" being the path to that certificate file. You can get this file by downloading the curl package (http://curl.haxx.se/download.html) and looking for it in the lib folder.

Feel free to email me.

If you are trying to use CURLOPT_FOLLOWLOCATION and you get this warning:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set...

then you will want to read http://www.php.net/ChangeLog-4.php which says "Disabled CURLOPT_FOLLOWLOCATION in curl when open_basedir or safe_mode are enabled." as of PHP 4.4.4/5.1.5.  This is due to the fact that curl is not part of PHP and doesn't know the values of open_basedir or safe_mode, so you could comprimise your webserver operating in safe_mode by redirecting (using header('Location: ...')) to "file://" urls, which curl would have gladly retrieved.

Until the curl extension is changed in PHP or curl (if it ever will) to deal with "Location:" headers, here is a far from perfect remake of the curl_exec function that I am using.

Since there's no curl_getopt function equivalent, you'll have to tweak the function to make it work for your specific use.  As it is here, it returns the body of the response and not the header.  It also doesn't deal with redirection urls with username and passwords in them.

<?php

    {
        static
$curl_loops = 0;
        static
$curl_max_loops = 20;

$curl_loops = 0;
            return
FALSE;
        }
       
curl_setopt($ch, CURLOPT_HEADER, true);
       
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
       
$data = curl_exec($ch);
        list(
$header, $data) = explode("\n\n", $data, 2);
       
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        if (
$http_code == 301 || $http_code == 302)
        {
           
$matches = array();
           
preg_match('/Location:(.*?)\n/', $header, $matches);
           
$url = @parse_url(trim(array_pop($matches)));
            if (!
$url)
            {
               
//couldn't process the url to redirect to
               
$curl_loops = 0;
                return
$data;
            }
           
$last_url = parse_url(curl_getinfo($ch, CURLINFO_EFFECTIVE_URL));
            if (!
$url['scheme'])
               
$url['scheme'] = $last_url['scheme'];

Note that if you want to use a proxy and use it as a _cache_, you'll have to do:

<?php curl_setopt($ch, CURLOPT_HTTPHEADER, array("Pragma: ")); ?>

else by default Curl puts a "Pragma: no-cache" header in and thus force cache misses for all requests.
Philippe dot Jausions at 11abacus dot com 30-May-2006 08:31
Clarification on the callback methods:

- CURLOPT_HEADERFUNCTION is for handling header lines received *in the response*,
- CURLOPT_WRITEFUNCTION is for handling data received *from the response*,
- CURLOPT_READFUNCTION is for handling data passed along *in the request*.

The callback "string" can be any callable function, that includes the array(&$obj, 'someMethodName') format.

Sometimes you can't use CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE becoz of the server php-settings(They say u may grab any files from server using these options). Here is the solution
1)Don't use CURLOPT_FOLLOWLOCATION
2)Use curl_setopt($ch, CURLOPT_HEADER, 1)
3)Grab from the header cookies like this:
preg_match_all('|Set-Cookie: (.*);|U', $content, $results);   
$cookies = implode(';', $results[1]);
4)Set them using curl_setopt($ch, CURLOPT_COOKIE,  $cookies);

Good Luck, Yevgen

The examples below for HTTP file upload work great, but I wanted to be able to post multiple files through HTTP upload using HTML arrays as specified in example 38.3 at

http://php.net/features.file-upload

In this case, you need to set the arrays AND keys in the $post_data, it will not work with just the array names. The following example shows how this works:

<?php

    $post_data
= array();
   
   
$post_data['pictures[0]'] = "@cat.jpg";
   
$post_data['pictures[1]'] = "@dog.jpg";
   

   
$ch = curl_init();
   
curl_setopt($ch, CURLOPT_URL, "http://example.com/my_url.php" );
   
curl_setopt($ch, CURLOPT_POST, 1 );
   
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   
$postResult = curl_exec($ch);

    if (
curl_errno($ch)) {
       print
curl_error($ch);
    }
   
curl_close($ch);
    print
"$postResult";
?>

If you're getting trouble with cookie handling in curl:

- curl manages tranparently cookies in a single curl session
- the option
<?php curl_setopt($ch, CURLOPT_COOKIEJAR, "/tmp/cookieFileName"); ?>

makes curl to store the cookies in a file at the and of the curl session

- the option
<?php curl_setopt($ch, CURLOPT_COOKIEFILE, "/tmp/cookieFileName"); ?>

makes curl to use the given file as source for the cookies to send to the server.

so to handle correctly cookies between different curl session, the you have to do something like this:

<?php
       $ch
= curl_init();
      
curl_setopt ($ch, CURLOPT_URL, $url);
      
curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE_PATH);
      
curl_setopt ($ch, CURLOPT_COOKIEFILE, COOKIE_FILE_PATH);

      
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
      
$result = curl_exec ($ch);
      
curl_close($ch);
       return
$result;
?>

in particular this is NECESSARY if you are using PEAR_SOAP libraries to build a webservice client over https and the remote server need to establish a session cookie. in fact each soap message is sent using a different curl session!!

I hope this can help someone

To further expand upon use of CURLOPT_CAPATH and CURLOPT_CAINFO...

In my case I wanted to prevent curl from talking to any HTTPS server except my own using a self signed certificate. To do this, you'll need openssl installed and access to the HTTPS Server Certificate (server.crt by default on apache)

You can then use a command simiar to this to translate your apache certificate into one that curl likes.

$ openssl x509 -in server.crt -out outcert.pem -text

Then set CURLOPT_CAINFO equal to the the full path to outcert.pem and turn on CURLOPT_SSL_VERIFYPEER.

If you want to use the CURLOPT_CAPATH option, you should create a directory for all the valid certificates you have created, then use the c_rehash script that is included with openssl to "prepare" the directory.

If you dont use the c_rehash utility, curl will ignore any file in the directory you set.

There is really a problem of transmitting $_POST data with curl in php 4+ at least.
I improved the encoding function by Alejandro Moreno to work properly with mulltidimensional arrays.

<?php
function data_encode($data, $keyprefix = "", $keypostfix = "") {
 
assert( is_array($data) );
 
$vars=null;
  foreach(
$data as $key=>$value) {
    if(
is_array($value)) $vars .= data_encode($value, $keyprefix.$key.$keypostfix.urlencode("["), urlencode("]"));
    else
$vars .= $keyprefix.$key.$keypostfix."=".urlencode($value)."&";
  }
  return
$vars;
}

curl_setopt($ch, CURLOPT_POSTFIELDS, substr(data_encode($_POST), 0, -1) );

Resetting CURLOPT_FILE to STDOUT won't work by calling curl_setopt() with the STDOUT constant or a php://output stream handle (at least I get error messages when trying the code from phpnet at andywaite dot com). Instead, one can simply reset it as a side effect of CURLOPT_RETURNTRANSFER. Just say

<?php curl_setopt($this->curl,CURLOPT_RETURNTRANSFER,0); ?>

and following calls to curl_exec() will output to STDOUT again.

when specifing the file for either CURLOPT_COOKIEFILE or CURLOPT_COOKIEJAR you may need to use the full file path instead of just the relative path.

After setting CURLOPT_FILE, you may want want to revert back to the normal behaviour of displaying the results. This can be achieved using:

Problems can occur if you mix CURLOPT_URL with a 'Host:' header in CURLOPT_HEADERS on redirects because cURL will combine the host you explicitly stated in the 'Host:' header with the host from the Location: header of the redirect response.

In short, don't do this:

<?php
$host
= "www.example.com";
$url = "http://$host/";

$headers = array("Host: $host");

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

Do
this instead:

$host = "www.example.com";
$url = "http://$host/";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
?>

Using cURL, I needed to call a third-party script which was returning binary data as attachment to pass on retrieved data again as attachment.

Problem was that the third-party script occassionally returned HTTP errors and I wanted to avoid passing on zero-length attachment in such case.

Combination of using CURLOPT_FAILONERROR and CURLOPT_HEADERFUNCTION callback helped to process the third-party script HTTP errors neatly:

<?php
function curlHeaderCallback($resURL, $strHeader) {
    if (
preg_match('/^HTTP/i', $strHeader)) {
       
header($strHeader);
       
header('Content-Disposition: attachment; filename="file-name.zip"');
    }
    return
strlen($strHeader);
}

$strURL = 'http://www.example.com/script-whichs-dumps-binary-attachment.php';

$resURL = curl_init();
curl_setopt($resURL, CURLOPT_URL, $strURL);
curl_setopt($resURL, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($resURL, CURLOPT_HEADERFUNCTION, 'curlHeaderCallback');
curl_setopt($resURL, CURLOPT_FAILONERROR, 1);

curl_exec ($resURL);

$intReturnCode = curl_getinfo($resURL, CURLINFO_HTTP_CODE);
curl_close ($resURL);

if (
$intReturnCode != 200) {
    print

Hi!

I have found some information I am sure it could help lot of programmers when they want to connect with curl to any https website and they haven't a good or right CA Cert :)

I give you just one example It has resolved me 2 hours of my time looking for a solution.

It is simple, just if you get any error in the curl_exec (use curl_error(...) to see the error to trace it) add the next line and everything is solved:

(note: replace $ch with the right curl variable)

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

<?php

$ch
= curl_init();
$res= curl_setopt ($ch, CURLOPT_URL,"https://yoururl/cgi");

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "Idc=si&");
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$xyz = curl_exec ($ch);

curl_close ($ch);
echo
$xyz;
if (
$xyz == NULL) {
           echo
"Error:<br>";
           echo
curl_errno($ch) . " - " . curl_error($ch) . "<br>";
}
?>

I hope this helps.

If you specify a CAINFO, note that the file must be in PEM format! (If not, it won't work).
Using Openssl you can use:
openssl x509 -in <cert> -inform d -outform PEM -out cert.pem
To create a pem formatted certificate from a binary certificate (the one you get if you download the ca somewhere).

A bit more documentation (without minimum version numbers):

- CURLOPT_WRITEFUNCTION
- CURLOPT_HEADERFUNCTION
  Pass a function which will be called to write data or headers respectively. The callback function prototype:

long write_callback (resource ch, string data)

The ch argument is CURL session handle. The data argument is data received. Note that its size is variable. When writing data, as much data as possible will be returned in all invokes. When writing headers, exactly one complete header line is returned for better parsing.
The function must return number of bytes actually taken care of. If that amount differs from the amount passed to this function, an error will occur.

- CURLOPT_READFUNCTION
  Pass a function which will be called to read data. The callback function prototype:

string read_callback (resource ch, resource fd, long length)

The ch argument is CURL session handle. The fd argument is file descriptor passed to CURL by CURLOPT_INFILE option. The length argument is maximum length which can be returned.
The function must return string containing the data which were read. If length of the data is more than maximum length, it will be truncated to maximum length. Returning anything else than a string means an EOF.

[Note: there is more callbacks implemented in current cURL library but they aren't unfortunately implemented in php curl interface yet.]

I managed to use curl to retrieve information from severs on ports other than 80 or 443 (for https) on some installations but not on all.
If you get an "CURLE_COULDNT_CONNECT /* 7 */" error, try adding the port : (for example)

<?php curl_setopt($ch, CURLOPT_PORT, $_SERVER['SERVER_PORT']); ?>

'-' means stdout

About the CURLOPT_HTTPHEADER option, it took me some time to figure out how to format the so-called 'Array'. It fact, it is a list of strings. If Curl was already defining a header item, yours will replace it. Here is an example to change the Content Type in a POST:

<?php curl_setopt ($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/xml")); ?>

23-Oct-2002 09:04
beware that not all cURLlib constants are supported under php :
e.g. CURLOPT_PROGRESSFUNCTION or CURLOPT_WRITEDATA are not supported.

CURLOPT_WRITEFUNCTION, although undocumented is supported. It takes the name of a user_defined function.
the function should take two arguments (the curl handle, and the inputdata) and return the length of the written data
e.g.

<?php
function myPoorProgressFunc($ch,$str){
global
$fd;
$len = fwrite($fd,$str);
print(
"#");
return
$len;
}

curl_setopt($ch,CURLOPT_WRITEFUNCTION,"myPoorProgressFunc");
?>

Also be aware that CURLOPT_WRITEFUNCTION  does NOT take the CURLOPT_FILE as a parameter!
in curl lib it would take CURLOPT_WRITEDATA but this is not supported by php; that's why I use "global $fd;" in my exemple function.

CURLOPT_HEADERFUNCTION works the same, and is guaranteed to receive complete header lines as input!

Hope this helps

$file
= "file_to_upload.txt";
$submit_url = "http://www.example.com/upload_page.php";

$formvars = array("cc"=>"us \n");
$formvars[variable_1] = "bla bla \n";
$formvars[variable_2] = "bla bla \n";
$formvars[variable_3] = "bla bla \n";
$formvars[variable_4] = "bla bla \n";
$formvars[upfile] = "@$file"; // "@" causes cURL to send as file and not string (I believe)

    // init curl handle
   
$ch = curl_init($submit_url);
   
curl_setopt($ch, CURLOPT_COOKIEJAR, "my_cookies.txt");  //initiates cookie file if needed
   
curl_setopt($ch, CURLOPT_COOKIEFILE, "my_cookies.txt");  // Uses cookies from previous session if exist
   
curl_setopt($ch, CURLOPT_REFERER, "http://www.example.net");  //if server needs to think this post came from elsewhere
   
curl_setopt($ch, CURLOPT_VERBOSE, 1);
   
curl_setopt($ch, CURLOPT_HEADER, 1);
   
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1); // follow redirects recursively
   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   
curl_setopt($ch, CURLOPT_POSTFIELDS, $formvars);

   
// perform post
   
echo $pnp_result_page = curl_exec($ch);
   
curl_close ($ch);

?>

CURLOPT_HTTPHEADER is NOT like the -H command line switch. The command line switch adds or replaces headers (much like the header() line in PHP, but for HTTP clients instead of servers), but the curl extension will eliminate the headers cURL sends by default.

For instance, your Authorization, Host, Referer, Pragma, and Accept headers which are normally written by default or by other CURLOPT_*'s.

Also, it might seem intuitive that this should accept an array hash of header->values, but this is not the case. It accepts an array of strings of the format "Header: Value", much like the -H command-line switch.

Hope this helps,

It's possible to take advantage of multiple URLs on the same host in one curl_exec transaction ... just use multiple instances of CURLOPT_URL.

Example:

<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com/a.html");
curl_setopt($ch, CURLOPT_URL, "http://example.com/b.html");
curl_setopt($ch, CURLOPT_URL, "http://example.com/c.html");
curl_exec($ch);
curl_close($ch);
?>

... the URLs appear to be hit in the same order they are entered. This takes advantage of cURL's Persistant Connection capability if all the URLs are on the same host!

To collect cookies recieved with a request, set CURLOPT_COOKIEJAR "cookieFileName".  Then use CURLOPT_COOKIEFILE "cookieFileName" to recall them in subsequent transactions.

To make a POST in multipart/form-data mode

(to upload a file for example) you can use

<?php curl_setopt($ch,CURLOPT_POSTFIELDS,$post); ?>

where $post is an array :

<?php
$post
['key1'] = 'data1';
//  like a text field in a POST
$post['file1'] = '@filename1'
// upload filename1
?>

For more informations see the

curl_formparse man page.

CURLOPT_RETURNTRANSFER has the interesting behaviour of tacking a null char onto the end of the string.  This null char is actually on the end of the php string, and can cause some odd results if you're not expecting it to be there.

If you want to connect to a secure server for posting info/reading info, you need to make cURL with the openSSL options. Then the sequence is nearly identical to the previous example (except http_S_://, and possibly add the useragent):

<?php
curl_setopt
($ch, CURLOPT_URL,"https://example.com");
//some sites only accept your request if your browser looks legit, so send a useragent profile...
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
?>

If you'd like to include extra headers in your POST request, you can accomplish this by setting the following option:

CURLOPT_HTTPHEADER

This is similar to the CURL -H command line switch.

Thanks to Daniel Stenberg for pointing out this usefull feature!

Note: this option was first supported in PHP version 4.03 .

Just because the docs are rather sparse on this, to set multiple values in a cookie, you separate them with a semicolon, as usual. An example, yo set j to j and k to k:

<?php curl_setopt($ch,CURLOPT_COOKIE,"j=j;k=k"); ?>

I used to download www pages to my script and one of the pages was different in MS explorer and different, when I downloaded it. Namely, information, I was really interested in was missing. That was because the server on the other bank of the river was looking at who is downloading the page. Everything got fixed when I pretended I was MSIE. It is done with curl. Here is a function, that you may use in similar situation

<?php
function download_pretending($url,$user_agent) {
  
$ch = curl_init();
  
curl_setopt ($ch, CURLOPT_URL, $url);
  
curl_setopt ($ch, CURLOPT_USERAGENT, $user_agent);
  
curl_setopt ($ch, CURLOPT_HEADER, 0);
  
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
  
$result = curl_exec ($ch);
  
curl_close ($ch);
   return
$result;
}
?>
