Operating system: Linux
PHP version:      5.2.6
PHP Bug Type:     Feature/Change Request
Bug description:  Magic function __cast($to) 

Description:
------------
The same way __toString is implemented, i suggest new magics functions
__toBool, __toInt, __toArray, or maybe, as suggested on php.general, a
generic magic function __cast($type){}

An example of implementation could be
class error extends exeption {
 __toBool(){return false; }
}




Reproduce code:
---------------
<?
//by C. Guthrie
class MyClass {
  function __cast($type)
  {
   switch ($type)
   {
     case 'string':
       return 'Foo';
     case 'array':
       return array('Foo');
     case 'DomDocument':
       // etc.
   }
  }
}
$my = new MyClass();


$xml = (DomDocument)$foo;

It would return the result of __cast called with $type == 'DomDocument'.
