Sockets

[Nickrs]

First: Sory for my bad english.
Second: I don't know if that is the right section to post this. If not, please any moderator move to right place.

I'm using an php code to show the total online players, and in the middle of the code that is:

$out = socket_read($socket, 2048);

2048 is the socket number, right?

If yes, anyone know other sockets that I can use?

Example (repeating: just an example)

$out = socket_read($socket, 2049); -> The 2049 retourns the time of the game…

This makes any sense?
