In the example above, rather than busy looping, curl_multi_select() should be used. The call isn't adequately described in the php documentation, so you need to look at the libcurl-multi man page. curl_multi_fdset() on this page is curl_multi_select() here, and curl_multi_perform() is curl_multi_exec() here. Read on and write better code.

It's not good to use plain while cycle like in the example because you are going to consume all the cpu time just by checking if you are not done. E.g. using usleep(50) in the middle of while could solve that gracefully...

In the example shown, the calls to curl_multi_remove_handle() should include the resource as the first parameter:
curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
