Please read properly before posting. And also read 
http://www.php.net/foreach , especially the part with "Note:  Also note
that foreach operates on a copy of the specified array and not the array
itself."

And as was said, it only happens if you do $a =& $a; before the foreach
clause. If you don't do it, you get the expected result.

I'm afraid that is caused just by the line
    $a = "foo";
which re-sets the $a variable to string, so it is no longer an array
and can't be enumerated by next loop...

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
