[RESOLVED] UDP Connection - How To?

Hi:

After reading php.net - i came up with this code
Unfortunately I get some errors.

PHP Code:

---

<?php
    echo "Quake 3 server test<H5>";
    
    // Quake 3 server
    $host = "213.249.227.8";
    $port = 27960;
    
    // Create a UDP Socket

    $socket = socket_create (AF_INET, SOCK_DGRAM, SOL_UDP);
    
    // Create the Q3 getstatus request
    $q3request = str_repeat(chr(0xFF),4)."getstatus".chr(0x0A);
    
    // Send the UDP Packet
    socket_sendto($socket, $q3request, strlen($q3request), 0x100, $host, $port);
    
    $buffer = '';
  $port = '';
  $ret = '';
    do
   {
     // $buffer and $port both come back with information for the ack
     // 516 = 4 bytes for the header + 512 bytes of data
     socket_recvfrom($socket, $buffer, 516, 0, $host, $port);

     // add the block number from the data packet to the ack packet
     $packet = chr(0) . chr(4) . substr($buffer, 2, 2);
     // send ack
     socket_sendto($socket, $packet, strlen($packet), 0, $host, $port);

     // append the data to the return variable
     // for large files this function should take a file handle as an arg
     $ret .= substr($buffer, 4);
   }
   while(strlen($buffer) == 516);  // the first non-full packet is the last.
    
    echo $ret
    
?>

And here are the associated output and errors

Code:

---

Hope someone can help - btw - this is my second php app lol

Cheers.

I resolved it :)
Rather than

PHP Code:

---

socket_sendto($socket, $q3request, strlen($q3request), 0x100, $host, $port); 


---

This works:

PHP Code:

---

socket_sendto($socket, $q3request, strlen($q3request), 0x0, $host, $port); 


---

Cheers....hope this helps someone
