Description:
------------
Hello. I opening udp socket on my ip adress  on closed port and fsock open don't return error, but when i trying make fread after fwrite i've got error reading socket.


Reproduce code:
---------------
function STAT_PACKET()
 {      
    $packet = pack("H*","FFFFFFFF");
    $packet .= "TSource Engine Query";
    $packet .= pack("H*","00");
    return $packet;
 } 
if (!$socket=fsockopen("udp://127.0.0.1",324,$errno,$errstr,2))
 {
    die("Error opening socket: $errstr<br>Code of error: $errno");
 }
fwrite ($socket,STAT_PACKET());
if (!$buff=fread ($socket,1000)){echo "Error reading socket";return false;} ;
$buffer = trim(substr($buff, 4));
if (!trim($buffer)) { echo "error";return false; }
fclose($socket);

Expected result:
----------------
Code print Error reading socket and return false then exit.
