PHP - Finding the Directory Depth

Hi there,

What I need is a simple way for PHP to return the current directory depth from the root of my website.

This may be something like counting the forward slashes, returning a number and running through case logic???

How can I achieve this??

Many thanx

If you know your paths are simple (i.e,   /a/b/c/d), the following may work for you.

count(split('/', $path));

or this to handle multiple /'s together

count(split('/+', $path));


still wouldn't handle a case like  /a/b/../c  correctly...since you'd have to canonicalize first.

Thank you. I really don't know what i'm doing here so could you help with the coding please.

I need to determine the current folder depth of the page being viewed.

So root would = 0
A directory off the root would = 1
A directory off of that directory would = 2, and so on...

Is this something you can help with?

Thank you

Try this:


$dir = $_ENV["DOCUMENT_ROOT"];
$parts = split("/", $dir);
 
$depth = count($parts);
