A cURL multi handle returned by curl_multi_init().
- still_running

A reference to a flag to tell whether the operations are still running.

范例
Example#1 curl_multi_exec() example
This example will create two cURL handles, add them to a multi handle, and then run them in parallel.
<?php
// create both cURL resources
$ch1 = curl_init ();
$ch2 = curl_init ();
// set URL and other appropriate options
curl_setopt ( $ch1 , CURLOPT_URL , "http://www.example.com/" );
curl_setopt ( $ch1 , CURLOPT_HEADER , 0 );
curl_setopt ( $ch2 , CURLOPT_URL , "http://www.php.net/" );
curl_setopt ( $ch2 , CURLOPT_HEADER , 0 );
//create the multiple cURL handle
$mh = curl_multi_init ();
//add the two handles
curl_multi_add_handle ( $mh , $ch1 );
curl_multi_add_handle ( $mh , $ch2 );
$running = null ;
//execute the handles
do {
$mrc = curl_multi_exec ( $mh , $running );
} while ( $mrc == CURLM_CALL_MULTI_PERFORM );
//close the handles
curl_multi_remove_handle ( $mh , $ch1 );
curl_multi_remove_handle ( $mh , $ch2 );
curl_multi_close ( $mh );
