Well one thing you shouldn't do is use double-quotes when assigning strings for later evaluation, particularly when they contain 'variables'. Thus this does NOT work: <?php $doo = "$doo = 'dah';"; # $ eval($doo); echo "Doo is $doo<br>"; ?> Whereas this does: <?php $doo = '$doo = \'dah\';'; eval($doo); echo "Doo is $doo<br>"; ?> -- Jason Wong -> Gremlins Associates -> www.gremlins.com.hk /* To program is to be. */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
