Prototypal inheritance for PHP classes
First, any class that you want to utilize prototyping must 1) extend the ProtoObject class (or a child of it) and 2) call the ProtoObject constructor (ProtoObject::__construct).
<?php
class MyClass extends ProtoObject {
public function __construct() {
ProtoObject::__construct();
}
}
?>Then, you can access the prototype chain either statically or through an instance of the class; however, if no instance has been created before you try to use prototyping statically, then you must first initialize the prototype chain by calling init_prototype():
<?php
MyClass::init_prototype();
MyClass::$prototype->one = 'foo';
$my_object = new MyClass();
echo $my_object->one; // outputs: foo
$my_object->prototype->one = 'bar';
echo $my_object->one; // outputs: bar
?>Prototypes can be methods, as well. Every prototype method must have a first parameter (eg. $self) in order to access the object in question (much the same way python methods work).
<?php
MyClass::$prototype->two = function($self) {
echo $self->one;
};
$my_object->two(); // outputs bar
?>
