How to call a protected method in php?

Question

here is the class structure. I want Observer:callme() to be callable from Children too.

class Observer
{
    protected callme()
    {
    }
}

class Parent exten         


        

Answer 1

I think I found the solution:

class Parent extends Observer
{
    function createChild()
    {
        $this->callme(); // this is OK
        return new Child (function() { $this->callme(); });
    }
}

class Child
{
    private $gatewayFunction;
    public function __constructor (Closure $gatewayFunction)
    {
        $this->gatewayFunction = $gatewayFunction;
    }

    public function __destroy()
    {
        $this->gatewayFunction->__invoke();
    }
}

Who is going to crap himself? :)
