There's no problem with variable names as parameters to copy() - you can test that in a few seconds. $ touch foo $ php -a Interactive mode enabled <?php $a = 'foo'; copy($a, $a . '.bak'); ?> $ ls foo foo.bak So the problem is elsewhere. 99 times in 100 you've either messed up the filenames or you've not got appropriate file permissions to do the copy. -robin
