Using SQL and checking constantly (constantly querying!) is very inefficient and a bad idea overall.

I suggest using sockets.

EDIT: Also, the preview has header warnings. It makes your code really look bad...

Another thing, I know the size of the code is small, but if you can organize things that are used in a lot of places into classes, things would be a lot more organised.

PHP код:

/*
    bool SQLClass ( string conIP, string conUser, string conPass, string conDatabase )
        This function initialises the SQL connection.
*/
class SQLClass {
    function SQLClass($conIP, $conUser, $conPass, $conDatabase) {
        ...
        return true;
    }
}
