[eluser]Blue Sapphire[/eluser]
Hi!
How can I get folder name, file name etc from following url:

http://localhost/rq/index.php/ad/dashboard

'ad' : is folder
'dashboard' : is file

Is there any built in function/code in 'CI' for getting above mention thing?

Thanks in advance

Dude just read user guide

http://ellislab.com/codeigniter/user-guide

There are no file or folder like old php style...

If you want to get that url part use

Code:

$this->uri->segment(n)
