<?php

class jokz {
    static public $val='123';
    static public function xxx() {
        jokz2(self);
    }
}

function jokz2($obj) {
    echo $obj::$val;
}

jokz::xxx();
?>

it returns fatal error, cause the class "self" couldn't be found... so.. how can i make that work?

fonksiyonunda referans bir parametre geçirerek de işe yaramazsa

function jokz2(&$obj) {
    echo $obj::$val;
}
