你如何通过子类调用构造函数？

Question

I need to call the constructor of the following class Foto

class Foto extends Galerie
{
    function __construct($a,$b)
    { }
}

via its child class. Something like:

class Album extends Foto
{
    function __construct($a,$b)
    { return $this->Foto[__construct] }
}

Any ideas? Hope you'll get my point.

Answer 1

parent::__construct($a,$b)

Is what you're looking for. You can also call parent class methods utilizing the same keyword.
