Bug description: Bug when using foreach on an array that has been referenced before
Description:
------------
When using foreach with an array that has been referenced before, it
behaves oddly if you re-set the variable inside the loop - it loses the
array it originally worked on. That doesn't happen if you leave the line
creating the reference out.
Reproduce code:
---------------
<?php
$a = array(1,2,3);
$b =& $a; // this line causes the bug
// $a =& $a; does it too
foreach($a as $v) {
print "$v\n";
$a = "foo";
}
Expected result:
----------------
1
2
3
Actual result:
--------------
1
Warning: Invalid argument supplied for foreach() in /home/et/test.php on
line 4
