maybe you should be foreach()ing with references? php.net : search "foreach" : As of PHP 5, you can easily modify array's elements by preceding $value with &. This will assign reference instead of copying the value. <?php $arr = array(1, 2, 3, 4); foreach ($arr as &$value) {

    $value = $value * 2;

} // $arr is now array(2, 4, 6, 8) unset($value); // break the reference with the last element ?> This is possible only if iterated array can be referenced (i.e. is variable),

References in foreach don't work the way you think they work. You will still incur the copy. At least I did when I tested earlier today :) Cheers, Rob. -- http://www.interjinn.com Application and Templating Framework for PHP
