PHP Remove JavaScript

by

this should do it:

echo preg_replace('/<script\b[^>]*>(.*?)<\/script>/is', "", $var);

/s is so that the dot . matches newlines too.

Just a warning, you should not use this type of regexp to sanitize user input for a website. There is just too many ways to get around it. For sanitizing use something like the http://htmlpurifier.org/ library
