Lol, I'll sum up my previous post
GET request is easier than POST
You have to open a TCP connection to the host
new socket = socket_open( "http://www.amxmodx.org"", 80, SOCKET_TCP, error );
You have to format a GET request
formatex( buff, 1023, "get http://forums.alliedmods.net/showthread.php?t=58038^r^n" );
t is a variable and 58038 the value of t
send the request
socket_send( socket, buff, 1024);
define a task to get the page
if (socket_change( socket) //check if there is something waiting in the socket
socket_recv( socket, buff, 1023) //put the socket in buff
If you wanna try if you php page works, just open telnet, type the request and see the result ...
