A way to wait for a message response by the socket or take the first message incoming.
Note that if the server turn offline, you have a socket resource, but while trying socket_read(), it gives you a warning message that will fill your hard drive kickly due to logging.
The example above try read the message at best 3 times, 3 seconds sleeping for another reading.
<?php
function waitResponse($response = "") {
$status = "";
$tries = 3;
$counter = 0;
while ($status == $response) {
$status = socket_read($socket, 1024);
if(!$status){
if($counter >= $tries){
break;
}else{
$counter++;
sleep(3);
}
}
}
return $response;
}
