Reading SA-MP Server Packets with PHP.

Why is this useful? Because you can create stuff like this.

First open the socket (Obviously replacing 127.0.0.1 with your servers ip and 1337 with your servers port):

Code:

$fp = fsockopen("udp://", "127.0.0.1", "1337", $errno, $errstr);

Now checking if the connection was a success and reading packets:

Code:

    if ($fp)
    {
        $packet = 'SAMP';
        $packet .= chr(strtok($ip, '.'));
        $packet .= chr(strtok('.'));
        $packet .= chr(strtok('.'));
        $packet .= chr(strtok('.'));
        $packet .= chr($port & 0xFF);
        $packet .= chr($port >> 8 & 0xFF);

        fwrite($fp, $packet);
        fread($fp, 11);
        $is_passworded = ord(fread($fp, 1));
        $plr_count  = ord(fread($fp, 2));
        $max_plrs   = ord(fread($fp, 2));
        $strlen    = ord(fread($fp, 4));
        $hostname   = fread($fp, $strlen);
        $strlen    = ord(fread($fp, 4));
        $gamemode   = fread($fp, $strlen);
        $strlen    = ord(fread($fp, 4));
        $mapname   = fread($fp, $strlen);
        fclose($fp);
    }

Now you can for example:

Code:

echo $gamemode;

this would output the servers gamemode text if it stored in the variable correctly.

v-hosting.co.uk, it's not exactly free. ($2) but you pay once and you have hosting for life. And it's extremely fast.

Awesome. $2 is cheap, Especially for life. Thanks.

I am curious what else you can do.. for me a tutorial should explain how things work, and give some different exemples, not just showing a know script and saying "This open socket" and "This check connection".. In a tutorial, all lines of script should be commented. You may be know how it work, but peolple who need a tutorial for open socket and check connection, probably they do not know how it work at all..

Re: [TUTORIAL] Reading SA-MP Server packets in PHP. - Google63 - 23.05.2009

you can do that with YSF(changing and adding rules = weburl, gravity etc. text).. a lot of easier

[phpnoob]

I am getting this error:

Fatal error: Only variables can be passed by reference in /data/multiserv/users/161811/projects/189964/www/b.php on line 12

with line 12 beeing this:

$fp = fsockopen("udp://", "127.0.0.1", "1337", $errno, $errstr);

(all strings can be changed, if i remove a param, the script stops)

Any solution?

[/phpnoob]

Re: [TUTORIAL] Reading SA-MP Server packets in PHP. - Kwarde - 13.10.2010

Yeah I had that too.
TRY this:

PHP Code:



<?php
$ip = ""; //SERVER IP!
$port = ""; //SERVER PORT!
 
$fp = fsockopen("udp://", $ip, $port, $errno, $errstr);
//The code ...
?>

If that\'s not working, I recommend this: https://sampforum.blast.hk/showthread.php?tid=104299
