Having a little trouble with this static 'inheritance' in php 5.3 I need to test if a static function exists in static class but I need to test it from inside a parent static class.

I know in php 5.3 I can use the 'static' keyword to sort of simulate 'this' keyword. I just can't find a way to test if function exists.

İşte bir örnek:

// parent class
class A{

// class B will be extending it and may or may not have 
// static function name 'func'
// i need to test for it

    public static function parse(array $a){
        if(function_exists(array(static, 'func'){
            static::func($a);
        }
    }
}

class B extends A {
    public static function func( array $a ){
        // does something
    }
}

So now I need to execute B::parse(); the idea is that if subclass has a function, it will be used, otherwise it will not be used.

Denedim:

function_exists(static::func){}
isset(static::func){}

Bu 2 çalışmıyor.

Any ideas how to do this? By the way, I know about the possibility to passing a lambda function as a workaround, this is not an option in my situation.

Ben sadece şu an düşünemiyorum çok basit bir çözüm var bir his var.

Şimdi aramak gerekiyor
