[thelist] PHP - get one directory from a path?

[Robert Douglas]

Hey Stephen,

Using the 'explode' function on your url creates an array of your
directories - you can then access each of the directory names
individually.

Eg. 
$urlToExplode = dirName($_SERVER['PHP_SELF']); // This gives us just the
path of the current page (in your case '/main/something/inner')
$delimiter = "/";
$explodedUrl = explode(delimiter,urlToExplode);
$middleDirectory = $explodedUrl[1];

It may not be the most elegant solution and you could reduce it to a
couple lines, but as a beginner it makes sense to me as I can see the
component parts as I debug.

Good luck,
Rob.

Hi --

I'm trying to figure out a straightforward way to set a PHP variable  
to a particular directory in a path.

For example:  I have http://www.example.com/main/something/inner/ 
index.php
The path can change, though.  Specifically, the directory "something"  
is arbitrary -- the script could be running in http://www.example.com/ 
main/whatever/inner/ and so forth.

When the script runs, I want to set a variable to = "something", or  
whatever that directory name happens to be.

I know how to get the last directory name using dirname() and such,  
but I can't figure out how to get the directory two levels up....

Any ideas?  Thanks in advance!

Stephen Rider
