Note Submitter: mike dot d dot richman at gmail dot com ---- AKAM -- Your example does shorten your code, but I think it could cause trouble. If I understand correctly, one could design any form that posts to your page. Possible problems I can think of: 1) A crafted form contains a field that overwrites an important, existing variable in your script. 2) A crafted form posts an absurd number of variables, possibly slowing down your script. 3) A crafted form posts excessively large variables (I'm not sure what this can cause but it can't be good). If you do the following, you can specify which data you want while perhaps still shortening your code: <?php $vars = array ('name', 'email', 'content'); foreach ($vars as $var) { $$var = $_POST[$var]; } ?>
