// create both cURL resources
$ch1 curl_init();
$ch2 curl_init();

// set URL and other appropriate options
curl_setopt($ch1CURLOPT_URL"http://www.example.com/");
curl_setopt($ch1CURLOPT_HEADER0);
curl_setopt($ch2CURLOPT_URL"http://www.php.net/");
curl_setopt($ch2CURLOPT_HEADER0);

//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!
