xss_clean() is to clean tag script which maybe harmfull for your site by user input ( register, save data, etc ), ex :

Code:

&lt;script type="text/javascript"&gt; for (var i=1;i<=1000;i++) alert('heii..');&lt;/script&gt;

become

Code:

[removed] for (var i=1;i<=1000;i++) alert('heii..'); [/removed]
