VIDEO Tutorial: Clear HTML Tags from a string

This is my first video tutorial.

So this function is very usefull for cleaning post comments, contact forms and many other things.

The source code:

<?php
 
function clearHTML($str,$preg='<[^>]*>'){
	return preg_replace('/'.$preg.'/','',$str);
}
 
echo clearHTML($_GET['text']);
 
?>
