$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(

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!
