how do you detect a directory name with php?

Question

I know how to grab the URL but how do i detect just the directory name and get that asigned to a var... I started with pathinfo() but im stuck now

for example "abc/efg/index.php"

how do I get "efg"

Answer 1

an easy way is just to use explode("/",$url);

ignore the last value and all the rest are directories.

Answer 2

You can use a function in PHP called "is_dir" from there you can use different string functions like pregmatch to pull what you need. Check out the link below for more info or post this question on http:prydain.futurecis.com/Forums. Hope this helps.
