Bug description: foreach and object members mixing badly
Description:
------------
This might be related to #5052. The code below illustrates the problem
pretty well -- the class method should be returning a fresh copy of the
field but in fact the return value is sharing the foreach-counter so that
nested foreaches break. If I do something to force a copy, like
"$foo->_member =& $foo->_member" (I have no idea *why* this forces a
copy), then it works.
Reproduce code:
---------------
<?
class foo {
var $_member = array(1, 2, 3);
function member() {
return $this->_member;
}
}
$foo = new foo();
#$foo->_member =& $foo->_member;
$size = 0;
foreach ($foo->member() as $v) {
$size++;
foreach ($foo->member() as $v) {}
}
if ($size < count($foo->member())) die("BUG FOUND");
Expected result:
----------------
I expect $size == count($foo->member()). If you uncomment the commented
line, it works.
Actual result:
--------------
The inner foreach iterates through every value, but the outer foreach only
iterates through the first value.
