Hi All,

in prior 5.1, it is allowed to do:
class MyClass {
public function __set($key, &$value) {}
}
$c = new MyClass();
$c->d=10;

in 5.1 up:
that code result this:
Fatal error: Couldn't execute method MyClass::__set in Unknown on line 0

I have submit this bug.
My question is, is it possible to assign as reference using setter method ?

So here the answer in slightly more words: No, you have to keep the
signature of __set() thus you cannot assign references using __set().
This was an error we fixed with 5.1.0.

Best regards,
 Marcus

Assign by reference is not possible with __set() method.

Thanks. Dmitry.
