Re: Question on explode and join.

Hi. I have just added a profanity filter to a current project which runs like so (all form values are passed into the session after checking for required fields etc). $swearbox is an array containing profanities so I won't include it here! $_SESSION['profane'] = false; foreach ($_POST as $value) {

       foreach ($swearbox as $profanity) {
           if (preg_match("/$profanity/i", $value)) {
           $errors = true;
           $_SESSION['profane'] = true;
           mail(TECHEMAIL, 'profane content attack attempt on DJST', "From:

{$_SERVER['REMOTE_ADDRESS']} Time: " . date('d F Y G:i:s', time()-TIMEDIFF), 'whoops@dontjustsitthere.co.uk');

           }
       }

} ...if $errors is true at the end of processing I send the user back to the form. In this instance if there are rude words $_SESSION['profane'] is set and we warn the user.
