Getting the directory name from the address bar

mrgrammar

I need to get the current directory name to be able to use it as a variable on the page.

For example, if a user accesses:

http://www.example.com/demo/

I need to get "demo" from the url in order to use it as a variable.

How can I do that?

Would it be any different when the page name is specified in the url since I don't need the page name, just the directory name. For example:

http://www.example.com/demo/gotcha.php

I still only need the directory name: demo

Thanks in advance for your help.

$dir = prev(end(explode('/', $SERVER['REQUEST_URI'])));

this should work... basically it takes the full adress bar...

makes an array.... and takes the next to last element from the array...

[url]http://[/url]
www.somesite.com/
somedir/
thisdir/
thispage.html?somevar=thisvalue

would return 'thisdir'

or should....

Thanks for responding so quickly. Being new to PHP, I do not yet know how to work with arrays. (I will soon! 🙂 )However, after looking at your code snippet and a couple of other posts, I came up with this:

$pathwithrequesturi = $_SERVER['REQUEST_URI'];

$pathwithdirname = dirname($pathwithrequesturi);

echo $pathwithdirname;

For: http://www.example.com/demo/testgeturl.php

It returns: /demo

All I need to do now is get rid of the preceding slash so that all I get is:

demo

How do I remove the slash?

laserlight

$pathwithdirname = ltrim($pathwithdirname, '/');

You might want a somewhat more concise variable name, though.

Also, look at [man]pathinfo/man and [man]parse_url/man.

hehe, oke so my method was a bit excessive 😃

A little excessive? Yes. But it was what I needed to get the process started. Great thanks to both of you!!!

$array = parse_url ("http://" . $SERVER['HTTP_HOST'] . $SERVER['REQUEST_URI']);

print_r ($array);
