fsockopen udp not returning any output on my host

[SwiftR]

Hi, I have made a small script to obtain data from a call of duty game server and display it on a browser. Everything is working fine in my localhost server (Wamp Server 2.2).

When I move the script to my host in bluehost.com it doesn't return any error but doesn't return an output either. I can't find out why. I am not sure if the problem is in the code, please take a look at it.

 

<?php

$connect = fsockopen( "udp://" . "85.236.102.73", "28960", $errno, $errstr, 30 );
if( ! $connect ) exit( 'fsockopen did not connect' );

socket_set_timeout( $connect, 1, 0 );

$send = "\xFF\xFF\xFF\xFFgetstatus\x00";

fwrite( $connect, $send );
fputs( $connect, $send );

$output = fread( $connect, 5000 );

if( ! empty( $output ) ) {
  do {
        $status_pre = socket_get_status( $connect );
        $output = $output . fread( $connect, 5000 );
        $status_post = socket_get_status( $connect );
  }
  while( $status_pre['unread_bytes'] != $status_post['unread_bytes'] );
}
fclose( $connect );

echo $output;

?>

 

$errno returns 0 and $errstr returns nothing. I ran a fsockopen test i found on google, it was supposed to show bbc.com website title and it did so fsockopen is working. It wasn't an udp connection though so I am not sure if it is the problem. Could it be my host? What can I do?

 

$output is supposed to return something like this: ����statusResponse \_Admin\mh170085admin\_Email\clanservers@multiplay.co.uk\_GV_strea...

 

Please help, thanks.

Why are you calling fwrite () twice? I suspect this might be the cause of your problems.

Tested the (correct) code myself, and it worked for me:

$c = fsockopen ("udp://85.236.102.73", 28960, $errno, $errstr, 30);
if (!$c) {
    die ($errno.": ".$errstr);
}

socket_set_timeout ($c, 1000);
$send = "\xFF\xFF\xFF\xFFgetstatus\x00";

fwrite ($c, $send);
$output = fread ($c, 5000);

var_dump ($output);
// string(529) "����statusResponse\_Admin\mh170085admin\_Email\clanservers@multiplay.co.uk\_GV_streaming\enabled - CB v7.2\_Location\London, UK\_Website\http://www.multiplay.co.uk\fs_game\main\g_antilag\0\g_gametype\sd\g_needpass\1\gamename\Call of Duty 2\mapname\mp_dawnville\protocol\118\scr_friendlyfire\1\scr_killcam\0\shortversion\1.3\sv_allowAnonymous\0\sv_floodProtect\1\sv_hostname\Multiplay :: SCWTIRFLT\sv_maxclients\10\sv_maxPing\0\sv_maxRate\25000\sv_minPing\0\sv_privateClients\0\sv_punkbuster\1\sv_pure\1\sv_voice\0\pswrd\1\mod\1"

Again that script works on localhost but not on my Bluehost.com host.

This time it seems to enter a loop, the page loading animation doesn't disappear and nothing is shown on the page.

 

Edit: I fixed the loading *problem* with socket_set_timeout( $c, 1, 0 );

Now all it returns is: string(0) ""

Then it sounds like your host might be blocking outgoing communication. I recommend sending them an e-mail asking them about it, and if there are any possibilities to get what you need working.

[SwiftR]

Already did, I am waiting for an answer now.

Thanks for your script anyway, made it simpler.

[Christian F.]

You're welcome.
