Example of a decorator, which adds array access to any object:
<?php
class ArrayAccessDecorator implements ArrayAccess {
protected $object = null;
public function __construct($object){
$this->object = $object;
}
public function __call($method, $args){
return $this->productpart->$method($args);
}
public function __set($key, $val){
$this->object->$key = $val;
}
public function __get($key){
return $this->object->$key;
}
/* ArrayAccess */
public function offsetSet($key, $value){
$this->__set($key, $value);
}
public function offsetGet($key){
return $this->__get($key);
}
public function offsetUnset($key){
$this->__set($key, null);
}
public function offsetExists($offset){
$test = $this->object->__get($offset);
if($test !== null){
return true;
} else {
return false;
}
}
}
$stdobject = (object)array('test'=>'test', 'test2' =>
'test2');
$arr = new ArrayAccessDecorator($stdobject);
print $arr['test']; // test
$arr['test'] = 'hello';
print $arr['test']; // hello
?>
