// create both cURL resources
$ch1 = curl_init();
$ch2 = curl_init();
// set URL and other appropriate options
curl_setopt($ch1, CURLOPT_URL, "http://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);
//execute the multi handle
do {
$status = curl_multi_exec($mh, $active);
if ($active) {
// Wait a short time for more activity
curl_multi_select($mh);
}
} while ($active && $status == CURLM_OK);
//close the handles
curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
