Bug description: Call-time pass-by-reference has been deprecated but without it it's
impossible to pass a object-reference via call_user_function
Description:
------------
You *must* use Call-time pass-by-reference to pass a
object-reference when using call_user_function.
In the example changeA() is declared to use passing
by reference but it still doesn't work. I think
call_user_function should either try to discover if it's
passing by reference at runtime or just pass always by
reference.
Reproduce code:
---------------
<?php
class A {
var $_id = 'A';
function printID() {
print "A::id=[".$this->_id."]\n";
}
function remote(&$obj_ref, $obj_method) {
call_user_func(array(&$obj_ref, $obj_method), $this);
// this on works:
// call_user_func(array(&$obj_ref, $obj_method),&$this);
}
}
class B {
function changeA(&$obj) {
$obj->_id = 'B';
$obj->printID();
}
}
$a = new A();
$b = new B();
$a->printID();
$a->remote($b, 'changeA');
$a->printID();
?>
Expected result:
----------------
A::id=[A]
A::id=[B]
A::id=[B]
Actual result:
--------------
A::id=[A]
A::id=[B]
A::id=[A]
