Recuerda mucho a Javascript y frameworks tipo jQuery, para ello utiliza métodos encadenados y un objeto genérico:
// Define a new class
$animal = $class->new()
->def('init', function($t, $name) {
$t->name = $name;
})
->def('speak', function($t) {
echo "My name is $t->name\n";
});
// Extend a class
$dog = $animal->extend()
->def('speak', function($t) {
echo "My name is $t->name, I have just met you and I love you, SQUIRREL!\n";
})
->def('bark', function($t) {
echo "Woof!\n";
});
Para poder realizar esto se necesita crear la clase Obj:
class Obj {
public function __construct($methods=array()) {
$this->methods = $methods;
}
public function method($name) {
if (!isset($this->methods[$name]))
throw new BadMethodCallException();
return $this->methods[$name];
}
public function fn($name, $fn) {
$this->methods[$name] = $fn;
return $this;
}
public function __call($name, $args) {
return call_user_func_array(
$this->method($name),
array_merge(array($this), $args)
);
}
}
// Allow chaining method calls off the constructor..
function Obj($methods=array())
{
return new Obj($methods);
}
