Example #1 curl_multi_add_handle() example
This example will create two cURL handles, add them to a multi handle, and process them asynchronously.
<?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);
$running=null;
//execute the handles
do {
curl_multi_exec($mh,$running);
} while($running > 0);
//close all the handles
curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
curl_multi_close($mh);
?>
The 'do' loop in this example will cycle indefinitely until all curl downloads complete, needlessly using CPU cycles. A much better way is to block while dowloads are in progress. Refer to the example code on the curl_multi_exec() page instead, which does this!
