What is it all about? You posted it. You know where it came from and the site should have some information on it.

So you found some code, you have no idea what it does, but you put it on your website anyway?

A very simple Google search takes you to the Joomla site.

Or were you expecting someone to explain the code line by line?

This code is about 97 lines

guys . you really helped me with your answers . useless answers. i want to what it can do and that is all what i want

Are you stupid or just rude?

You have already been told what it is. Its part of the joomla cms.

http://www.joomla.org/

Read the comments I have added.

 * If this constant has not been set the script exits with       *

 * execute past this point.                                      *

You should be able to work the rest out from the comments I have added. I think you should also apoligise to the others after being so rude to them, they are trying to help you and your at fault for badly wording your question.

You want to know what it does? Have you tried it? Do you have the vaguest idea what it should be used for? Sounds to me like you've got hold of some random piece of code and thinking it looks impressive, posted here. So here's another useless answer for you. You'll keep getting them because of your idiotic initial question. Move on, life's too short - I can't imagine anybody here is going to have any patience with this.
