static yes, self no; and static is supported only in function scope, not 
in class scope; so, to store something statically in a class (instead of 
making it global, for instance), you would need to to something like this:

class aaa {
    function &bbb(){
        static $_kk;
        if(!isset($_kk)){
            $_kk = "";
        }
        return $_kk;
    }
}

$kk = &aaa::bbb();
echo var_export($kk, true), "\n";

$kk .= "asdfasfasfdasfd";

echo var_export(aaa::bbb(), true), "\n";

which outputs

''
'asdfasfasfdasfd'
