curl_multi_exec
Run the sub-connections of the current cURL handle
(PHP 5)
int curl_multi_exec ( resource mh, int &still_running )
Processes each of the handles in the stack. This method can be called whether or not a handle needs to read or write data.
Parameters
- mh
A cURL multi handle returned by curl_multi_init().
- still_running
A reference to a flag to tell whether the operations are still running.
Return Values
A cURL code defined in the cURL Predefined Constants.
Note:
This only returns errors regarding the whole multi stack. There might still have
occurred problems on individual transfers even when this function returns
CURLM_OK.
Examples
Example 434. 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);
?>
