Re: Searching a string or similar

if (strpos("<SCRIPT LANGUAGE = Javascript>",$input_string)===false) { echo("Yeah, right!"); exit; } You'll have a lot of problems, though, because 1. You also need to check for <script type="text/javascript">; 2. You have to strtolower() both strings in order to eliminate capitalization differences; 3. and the tougher: how do you check for this one: "<script language ='javascript' \t>", where "\t" is a tab character? And obviously all the possible combinations...
