get_browser
(PHP 4, PHP 5)
get_browser — ユーザのブラウザの機能を取得する
説明
ユーザのブラウザの機能を調べます。これは、browscap.ini ファイルのブラウザ情報を調べることにより行います。
パラメータ
- user_agent
-
処理するユーザエージェント。デフォルトでは、HTTP の User-Agent ヘッダの内容を使用します。しかし、このパラメータを渡すことでこれを変更する (別のブラウザの情報を取得する) ことが可能です。
このパラメータを処理しないようにするには NULL 値を渡します。
- return_array
-
TRUE を指定すると、この関数はオブジェクトでなく配列を返します。
返り値
情報は、オブジェクトあるいは配列形式で返されます。 たとえばブラウザのメジャーバージョン番号、マイナーバージョン番号や ID 文字列といったさまざまなデータが含まれています。また、 フレームや JavaScript、クッキーといった機能についての TRUE/FALSE 値も含んでいます。
cookies の値は、単にそのブラウザがクッキーを扱う機能を 有していることを示すだけであり、ユーザがクッキーを受け入れる設定に しているかどうかを表すものではありません。それをチェックする唯一の方法は、 いったん setcookie() でクッキーを設定してからリロードし、 その値を調べることです。
変更履歴
| バージョン | 説明 |
|---|---|
| 4.3.2 | オプションのパラメータ return_array が追加されました。 |
例
例1 ユーザのブラウザについての全情報の一覧
<?php
echo $_SERVER['HTTP_USER_AGENT'] . "\n\n";
$browser = get_browser(null, true);
print_r($browser);
?>
上の例の出力は、 たとえば以下のようになります。
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3
Array
(

注意
注意: この関数が正常に機能するためには、php.ini の browscap 設定が、システム上の browscap.ini の正確な位置を 指している必要があります。
browscap.ini は PHP にはバンドルされていません。 しかし、ここで最新の » php_browscap.ini を入手することができます。
browscap.ini は多くのブラウザに関する情報をもっていますが、 データベースを最新に保つのはユーザーによる更新に依存しています。 ファイルのフォーマット自体を見ればおおよそのことがわかります。

If you're just finding this API, note that you may want to use a lighter-weight
browser detection script. get_browser() requires the "browscap.ini" file,
which is 300KB+. Loading and processing this file will likely impact script
performance. Although it surely provides excellent detection results, in most
cases a much simpler method can be just as effective. This is why so many
previous commenters have provided alternate implementations.
Here's the solution I ended up using, which I've tested on the agents listed at
http://whatsmyuseragent.com/CommonUserAgents.asp It has the advantage of being
compact and reasonably easy to extend (just add entries to the $known array
defined at the top). It should be fairly performant as well, since it doesn't
do any iteratoin or recursion.
<?php
function browser_info($agent=null) {
// Declare known browsers to look for
$known = array('msie', 'firefox', 'safari', 'webkit', 'opera', 'netscape',
'konqueror', 'gecko');
// Clean up agent and build regex that matches phrases for known browsers
// (e.g. "Firefox/2.0" or "MSIE 6.0" (This only matches the major and minor
// version numbers. E.g. "2.0.0.6" is parsed as simply "2.0"
$agent = strtolower($agent ? $agent : $_SERVER['HTTP_USER_AGENT']);
$pattern = '#(?<browser>' . join('|', $known) .
')[/ ]+(?<version>[0-9]+(?:\.[0-9]+)?)#';
// Find all phrases (or return empty array if none found)
if (!preg_match_all($pattern, $agent, $matches)) return array();
// Since some UAs have more than one phrase (e.g Firefox has a Gecko phrase,
// Opera 7,8 have a MSIE phrase), use the last one found (the right-most one
// in the UA). That's usually the most correct.
$i = count($matches['browser'])-1;
return array($matches['browser'][$i] => $matches['version'][$i]);
}
?>
This returns an array with the detected browser as the key, and the version as
the value, and also sets 'browser' and 'version' keys. For example on Firefox
3.5:
<?php
$ua = browser_info();
print_r($ua);
/* Yields ...
Array
(
[firefox] => 3.5
[browser] => firefox
[version] => 3.5
)
*/
// Various browser tests you can do with the returned array ...
if ($ua['firefox']) ... // true
if ($ua['firefox'] > 3) ... // true
if ($ua['firefox'] > 4) ... // false
if ($ua['browser'] == 'firefox') ... // true
if ($ua['version'] > 3.5) ... // true
if ($ua['msie']) ... // false ('msie' key not defined)
if ($ua['opera'] > 3) ... // false ('opera' key not defined)
if ($ua['safari'] < 3) ... // false also ('safari' key not defined)
?>

This is a simple class to detect the client browser and version using regular expressions.
<?PHP

"Name" => "unknown",
"Agent" => "unknown") ;
public function __Construct()
{
$browsers = array("firefox", "msie", "opera", "chrome", "safari",
"mozilla", "seamonkey", "konqueror", "netscape",
"gecko", "navigator", "mosaic", "lynx", "amaya",
"omniweb", "avant", "camino", "flock", "aol");
$this->Agent = strtolower($_SERVER['HTTP_USER_AGENT']);
foreach($browsers as $browser)
{
if (preg_match("#($browser)[/ ]?([0-9.]*)#", $this->Agent, $match))
{
$this->Name = $match[1] ;
$this->Version = $match[2] ;
break ;
}
}
}
public function __Get($name)
{
if (!array_key_exists($name, $this->props))
{
die "No such property or function $name)" ;
}
return $this->props[$name] ;
}
public function __Set($name, $val)
{
if (!array_key_exists($name, $this->props))
{
SimpleError("No such property or function.", "Failed to set $name", $this->props) ;
die ;
}
$this->props[$name] = $val ;
}
}
?>
example code
<?PHP
$browser = new Browser ;
echo "$Browser->Name $Browser->Version" ;
?>
result when client using Firefox 3.0.11
firefox 3.0.11
result when client using unknown browser

Here is an improved version of admin at studio-gepard dot pl.
This code supports: minor versions, checking or return browser data and more browsers like Chrome, Flock and others and version compare.
<?php

$this_version = $this_browser = '';
$browser_limit = strlen($user_browser);
foreach (w($browser_list) as $row)
{
$row = ($a_browser !== false) ? $a_browser : $row;
$n = stristr($user_browser, $row);
if (!$n || !empty($this_browser)) continue;
$this_browser = $row;
$j = strpos($user_browser, $row) + strlen($row) + 1;
for (; $j <= $browser_limit; $j++)
{
$s = trim(substr($user_browser, $j, 1));
$this_version .= $s;
if ($s === '') break;
}
}

$a_sign = explode(' ', $a_version);
if (version_compare($this_version, $a_sign[1], $a_sign[0]) === false)
{
$ret = false;
}
}
}
return $ret;
}
//
$this_platform = '';
if (strpos($user_browser, 'linux'))
{
$this_platform = 'linux';
}
elseif (strpos($user_browser, 'macintosh') || strpos($user_browser, 'mac platform x'))

}
return array(
"browser" => $this_browser,
"version" => $this_version,
"platform" => $this_platform,
"useragent" => $user_browser
);
}
// Examples
echo '<pre>';

var_dump(_browser('msie', '>= 7.0')); // return true if using IE 7.0 or above else false
var_dump(_browser('firefox', '< 3.0.5')); // return true if using below firefox 3.0.5 (can check minor version)
var_dump(_browser(false, false, true)); // return string of name of browser and version
// To check if Gecko browser is used
var_dump(_browser('gecko'));
// version_compared function is used so you can use the same operator syntax
var_dump(_browser('firefox', 'le 1.5'));
echo '</pre>';

A newer version for those only interested in identifying A-grade browsers. The code was ported in part from JQuery 1.3.1.
<?php
class Browser {
/**
Figure out what browser is used, its version and the platform it is
running on.
The following code was ported in part from JQuery v1.3.1
*/
public static function detect() {
$userAgent = strtolower($_SERVER['HTTP_USER_AGENT']);
// Identify the browser. Check Opera and Safari first in case of spoof. Let Google Chrome be identified as Safari.
if (preg_match('/opera/', $userAgent)) {
$name = 'opera';
}
elseif (preg_match('/webkit/', $userAgent)) {
$name = 'safari';
}
elseif (preg_match('/msie/', $userAgent)) {
$name = 'msie';
}
elseif (preg_match('/mozilla/', $userAgent) && !preg_match('/compatible/', $userAgent)) {
$name = 'mozilla';
}
else {
$name = 'unrecognized';
}
// What version?
if (preg_match('/.+(?:rv|it|ra|ie)[\/: ]([\d.]+)/', $userAgent, $matches)) {
$version = $matches[1];
}
else {
$version = 'unknown';
}
// Running on what platform?
if (preg_match('/linux/', $userAgent)) {
$platform = 'linux';
}
elseif (preg_match('/macintosh|mac os x/', $userAgent)) {
$platform = 'mac';
}
elseif (preg_match('/windows|win32/', $userAgent)) {
$platform = 'windows';
}
else {
$platform = 'unrecognized';
}
return array(
'name' => $name,
'version' => $version,
'platform' => $platform,
'userAgent' => $userAgent
);
}
}
Usage:
$browser = TkBrowser::detect();
echo 'You browser is '.$browser['name'].' version '.$browser['version'].' running on '.$browser['platform'];

Daniel Frechette's code shown me "unrecognized" for way too many browsers so I decided to merge small part of his code with tectonikNOSPAM at free dot fr one. I also removed globals (which I never use), and made a function of it. Detects browser and platform. The input can be true - for array - or false - for simple string output. Tested - works on Win, Mac, and browsers specified.
<?php
function checkBrowser($input) {
$browsers = "mozilla msie gecko firefox ";
$browsers.= "konqueror safari netscape navigator ";
$browsers.= "opera mosaic lynx amaya omniweb";
$browsers = split(" ", $browsers);
$userAgent = strToLower( $_SERVER['HTTP_USER_AGENT']);
$l = strlen($userAgent);
for ($i=0; $i<count($browsers); $i++){
$browser = $browsers[$i];
$n = stristr($userAgent, $browser);
if(strlen($n)>0){
$version = "";
$navigator = $browser;
$j=strpos($userAgent, $navigator)+$n+strlen($navigator)+1;
for (; $j<=$l; $j++){
$s = substr ($userAgent, $j, 1);
if(is_numeric($version.$s) )
$version .= $s;
else
break;
}
}
}
if (strpos($userAgent, 'linux')) {
$platform = 'linux';
}
else if (strpos($userAgent, 'macintosh') || strpos($userAgent, 'mac platform x')) {
$platform = 'mac';
}
else if (strpos($userAgent, 'windows') || strpos($userAgent, 'win32')) {
$platform = 'windows';
}
if ($input==true) {
return array(
"browser" => $navigator,
"version" => $version,
"platform" => $platform,
"userAgent" => $userAgent);
}else{
return "$navigator $version";
}
}
/* USAGE: */
//array output:
$i = checkBrowser(false);
print_r($i);
//will give:
//Array ( [browser] => firefox [version] => 3.0 [platform] => windows [userAgent] => mozilla/5.0 (windows; u; windows nt 5.1; pl; rv:1.9.0.6) gecko/2009011913 firefox/3.0.6 )
//string output:
echo checkBrowser(true);
//will give: firefox 3.0

Use this to ensure that the costly call in its standard form never needs to be repeated:
<?php
function getBrowser(){

If the "browscap" directive isn't set in your server's php.ini, then an error warning is shown. Just in case, you could make a call to ini_get() to check if the browscap directive is set before using browser_get().
<?php
if(ini_get("browscap")) {
$browser = get_browse(null, true);
}

You should not rely on just this for cross-browser compatibility issues. Good practice would be to include HTML if-statements for IE stylesheets as well as dynamically checking the browser type.

So i added this to my browscap.ini manually:
[Mozilla/4.0 (compatible; MSIE 4.01; Windows NT)]
Parent=IE 4.01
Platform=WinNT

I thought this function might be useful to those without access to the php.ini file (such as those on a shared hosting system):
function php_get_browser($agent = NULL){
$agent=$agent?$agent:$_SERVER['HTTP_USER_AGENT'];
$yu=array();
$q_s=array("#\.#","#\*#","#\?#");
$q_r=array("\.",".*",".?");
$brows=parse_ini_file("php_browscap.ini",true);
foreach($brows as $k=>$t){
if(fnmatch($k,$agent)){
$yu['browser_name_pattern']=$k;
$pat=preg_replace($q_s,$q_r,$k);
$yu['browser_name_regex']=strtolower("^$pat$");
foreach($brows as $g=>$r){
if($t['Parent']==$g){
foreach($brows as $a=>$b){
if($r['Parent']==$a){
$yu=array_merge($yu,$b,$r,$t);
foreach($yu as $d=>$z){
$l=strtolower($d);
$hu[$l]=$z;
}
}
}
}
}
break;
}
}
return $hu;
}
define the location of php_browscap.ini wherever you want
always returns an array, same functionality as get_browser(NULL,true)
Hope someone finds it useful!

Here is a class I've created that supports an external browscap.ini file (configuration independent) and works faster than get_browser on multiple queries.

Here is what we do to fix the parsing error messages for php_browscap.ini downloaded from Gary's website.
<?php
// fix the browsecap.ini for php
$v= file_get_contents('php_browscap.ini');
$v= preg_replace("/\r/","",$v);
$v= preg_replace('/="(.*)"/i','=\\1',$v);
$v= preg_replace("/platform=(.*)/i","platform=\"\\1\"",$v);
$v= preg_replace("/parent=(.*)/i","parent=\"\\1\"",$v);
$v= preg_replace("/minorver=(.*)/i","minorver=\"\\1\"",$v);
$v= preg_replace("/majorver=(.*)/i","majorver=\"\\1\"",$v);
$v= preg_replace("/version=(.*)/i","version=\"\\1\"",$v);
$v= preg_replace("/browser=(.*)/i","browser=\"\\1\"",$v);
$v= str_replace("[*]","*",$v);
file_put_contents('browscap.ini',$v);
?>

This might be useful for some until the Gary Keith updates his library. I added this to my browscap.ini to detect the latest Safari update for Panther, and the new Safari in Tiger:
;;; Added manually 05.04.19 for Safari 1.3
[Mozilla/5.0 (Macintosh; U; PPC Mac OS X; *) AppleWebKit/* (*) Safari/31?]
parent=Safari
version=1.3
majorver=1
minorver=3
;;; Added manually 05.04.26 for Safari 2.0 (Shipped with Tiger)
[Mozilla/5.0 (Macintosh; U; PPC Mac OS X; *) AppleWebKit/* (*) Safari/41?]
parent=Safari
version=2.0
majorver=2
minorver=0
Note: Full $_SERVER['HTTP_USER_AGENT'] for Safari 2 (Tiger) is
Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/412 (KHTML, like Gecko) Safari/412
(Disclaimer: I do not know if the entries above conform to whatever syntax standard Gary uses in his file, but it works fine for me).

Another (short) sequential php script to determine browsers family and version.
<?
// _______
// ----- | CONF. |
//
// add new browsers in lower case here, separated
// by spaces - order is important: from left to
// right browser family becomes more precise
$browsers = "mozilla msie gecko firefox ";
$browsers.= "konqueror safari netscape navigator ";
$browsers.= "opera mosaic lynx amaya omniweb";
// _______
// ----- |PROCESS|
//
$browsers = split(" ", $browsers);
$nua = strToLower( $_SERVER['HTTP_USER_AGENT']);
$l = strlen($nua);
for ($i=0; $i<count($browsers); $i++){
$browser = $browsers[$i];
$n = stristr($nua, $browser);
if(strlen($n)>0){
$GLOBALS["ver"] = "";
$GLOBALS["nav"] = $browser;
$j=strpos($nua, $GLOBALS["nav"])+$n+strlen($GLOBALS["nav"])+1;
for (; $j<=$l; $j++){
$s = substr ($nua, $j, 1);
if(is_numeric($GLOBALS["ver"].$s) )
$GLOBALS["ver"] .= $s;
else
break;
}
}
}
// _______
// ----- | USE |
//
echo("<pre>Your browser is: ");
echo($GLOBALS["nav"] . " " . $GLOBALS["ver"] . "</pre>");
?>

Another PHP browser detection script that might be of use to you is here:
http://tech.ratmachines.com/downloads/php_browser_detection.php
This script uses a fairly different logic than get_browser, and doesn't worry about things like table/frame ability. This script was being used by mozdev to id Mozilla versions, since it specializes in that kind of specialized id. It also has unix/linux version os iding.

Be aware of the fact that this function shows what a specific browser might be able to show, but NOT what the user has turned on/off.
So maybe this function tells you that the browser is abel to to javascript even when javascript is turned off by the user.

PHP is sensitive to characters outside the range [ A-Za-z0-9_] as values in .ini files. For example
browser=Opera (Bork Version)
causes PHP to complain, as it doesn't like the parentheses.
If you place quotation marks around the values for all keys in the browscap.ini file, you'll save yourself parsing problems. Do this in eg vi with %s/=\(.*\)/="\1"/g
You could of course use PHP itself to fixup the file. Exercise left to the reader.

Please keep in mind that you should somehow (for example in session) cache the required results of get_browser() because it really slows thinks down.
We have experienced that without querying for browser data our scripts would run 120-130% faster. the explanation is that over 200kb long file (browscap.ini) has to be loaded and parsed everytime someone access any page (we need browser results on all pages).
So keep results in session and expect a performance boost.

phpSniff (noted in a few places above) is absolutely fantastic. I just installed it, and it is a godsend! It now handles all of my session information needed to go in my database. Thanks for you folks who posted that great Sourceforge resource! http://phpsniff.sourceforge.net/

Here's a quick way to test for a Netscape browser. IE and Konqueror and several others call themselves "Mozilla", but they always qualify it with the word "compatible."
$isns = stristr($HTTP_USER_AGENT, "Mozilla") && (!(stristr($HTTP_USER_AGENT, "compatible")));

The only way browscap examines the target browser is through the HTTP_USER_AGENT so there is no way you can determine installed plug-ins. The only way to do that is through client-side JavaScripts.
