PHP Get name of current directory

by 
getcwd();

or

dirname(__FILE__);

or (PHP5)

basename(__DIR__)

http://php.net/manual/en/function.dirname.php

You can use basename() to get the trailing part of the path 🙂

In your case, I’d say you are most likely looking to use getcwd(), dirname(__FILE__) is more useful when you have a file that needs to include another library and is included in another library.

Eg:

main.php
libs/common.php
libs/images/editor.php

In your common.php you need to use functions in editor.php, so you use

common.php:

require_once dirname(__FILE__) . '/images/editor.php';

main.php:

require_once libs/common.php

That way when common.php is require'd in main.php, the call of require_once in common.php will correctly includes editor.php in images/editor.php instead of trying to look in current directory where main.php is run.
