How to simulate a cast of a class in PHP (other than stdClass)?

It seems to me that in java there is a way to make casts to make a given object instance another.

Example:

MyClass variable = (MyClass) my_other_class;

In php it is possible to do casts of types, and even for object, which in the case is ALWAYS the stdClass .

Example:

$int = 1;
$object = (object) $int;
$array = (array) $int;
$str = (string) $int;

Now if I have, for example, a class that I defined and want to give a cast of any value to it, it is not possible.

Example:

$arr = array();

$obj = (object) $arr; // Retorna: stdClass

$myObj = (MyObject) $arr; // Retorna: Parse Error

Is there any way to simulate this in PHP?
