Only in PHP5.

http://us3.php.net/manual/en/control-structures.foreach.php

"Unless the array is referenced, foreach operates on a copy of the
specified array and not the array itself....As of PHP 5, you can easily
modify array's elements by preceding $value with &. This will assign
reference instead of copying the value."
