This's a example of Composite Pattern:
<?php
abstract class Graphic{
abstract public function draw();
}
class Triangle extends Graphic{
private $name = '';
public function __construct($name = 'unknown'){
$this->name = $name;
}
public function draw(){
echo '-I\'m a triangle '.$this->name.'.<br>';
}
}
class Container extends Graphic{
private $name = '';
private $container = array();
public function __construct($name = 'unknown'){
$this->name = $name;
}
public function draw(){
echo 'I\'m a container '.$this->name.'.<br>';
foreach($this->container as $graphic)
$graphic->draw();
}
public function add(Graphic $graphic){
$this->container[] = $graphic;
}
public function del(Graphic $graphic){
unset($this->container[$graphic]);
}
}
$tri1 = new Triangle('1');
$tri2 = new Triangle('2');
$tri3 = new Triangle('3');
$container1 = new Container('1');
$container2 = new Container('2');
$container3 = new Container('3');
$container1->add($tri1);
$container1->add($tri2);
$container2->add($tri3);
$container3->add($container1);
$container3->add($container2);
$container3->draw();
?>
The above example will output:
I'm a container 3.
I'm a container 1.
-I'm a triangle 1.
-I'm a triangle 2.
I'm a container 2.
-I'm a triangle 3.
