curl_multi_exec

(PHP 5)

curl_multi_exec — Run the sub-connections of the current cURL handle

说明

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.

参数

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.

返回值

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.

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);

?>
