Bug description: Overloaded array properties do not work correctly
Description:
------------
It is now impossible to implement overloaded array properties. Array
returned via __get is now a copy (not a reference as in 5.1.x) and it is
impossible to force getter to pass a reference.
Reproduce code:
---------------
<?php
class A {
public function & __get($val) {
return $this->keys[$val];
}
public function __set($k, $v) {
$this->keys[$k] = $v;
}
private $keys = array();
}
$a =new A();
$a->arr = array('a','b','c');
$b = &$a->arr;
$b[]= 'd';
foreach ($a->arr as $k => $v) {
echo "$k => $v\n";
}
$a->arr[]='d';
foreach ($a->arr as $k => $v) {
echo "$k => $v\n";
}
?>
Expected result:
----------------
0 => a
1 => b
2 => c
3 => d
0 => a
1 => b
2 => c
3 => d
4 => d
Actual result:
--------------
