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.

Is there any free hosts that support PHP and fsockopen/fclose.

I doubt it but whats the harm in asking?

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.

[On_Top_Non_Stop]

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

how do you get the gravity and weburl and weather and worldtime by reading the packets?

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..

[Google63]

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

Even my 3 year old brother figured out that both thread submitters have the same username. Palm your face. FACEPALM!

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]

[Kwarde]

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 ...
?>
