Simple String Parising. Help!

[bpops]

Ok, so I'm working on some code that will take a URL and display just the host and path (minus the page itself.) For example, given:

http://www.somedomain.com/blahblah/blah/whatever.html
will become
http://www.somedomain.com/blahblah/blah/

I've tried parse_url, but the problem is that will give the host (www.somedomain.com) and path (/blahblah/blah/whatever.html).
So it is of no use here.

I'm sure I can do this just by somehow having PHP look for the last forward slash, "/" in the string and truncating after that. Can someone help me out witha bit of code that might do this?

Thanks in advance!

I did this by explode. this way all the items are in elements in an array (split by "/"). If your file is always in the last element you can rebuild the string  minus the last element.

So, would this work?
[code]
$url = 'http://www.somedomain.com/blah/blah/whatever.html'
$url_arr = explode("/", $url)
$page = array_pop($url_arr)
$new_url = $implode("/",$url_arr)
[/code]

edit: the code is very small to read :P.    pasted:

$url = 'http://www.somedomain.com/blah/blah/whatever.html'
$url_arr = explode("/", $url)
$page = array_pop($url_arr)
$new_url = $implode("/",$url_arr)
