Apparently, Provjera is a function. You forgot to create the actual function.

PHP код:

Provjera(PARAMETERS)
{
    // Function code
    return 1;
} 


Please note that you have to edit 'PARAMETERS' to the correct parameters. By looking at your code, I assume it checks a string. In that case the parameter would be 'text[]'. The straight brackets are indicating that it's an array (used as a string) with an unknown size.

ZadnjaPoruka on the other hand is a variable, I guess that means muted, right?

PHP код:

new ZadnjaPoruka[MAX_PLAYERS]; // Somewhere ontop of your script. 


By declaring a variable I simply mean creating it.
