how to get url ?

Hi,
I'm using mod_rewrite in .htaccess on my homepage.
for example :

http://www.test.com/sony

will be rewrited to

http://www.test.com/company.php?name=sony

but I don't use the R option in the .htaccess so the shown url is still
the http://www.test.com/sony

My question is : if I use $_SERVER['PHP_SELF'] I get the
/company.php?name=sony not the /sony. How to get the /sony ??

Thanks

Donny
