PHP and URLS

Hello all, I was just wondering if it is possible to skip the file names and give the rest of the url with php.

Example:

If I enter http://www.mysite.com/hdgfuhd/gfjdhfjhsd/ufgd.php to give me http://www.mysite.com/hdgfuhd/gfjdhfjhsd/

Or:

If I enter http://www.mysite.com/fdgfd/fgdsfgssdgsd/dgfsdgdfg/hdgfuhd/gfjdhfjhsd/ufgddfdfs.php to give me http://www.mysite.com/fdgfd/fgdsfgssdgsd/dgfsdgdfg/hdgfuhd/gfjdhfjhsd/

Thanks
