Get parent folder of current file PHP

Question

I've done quite a bit of searching for this, so I'm sorry if this is a dupe.
Anyway, I need to get the name of the folder the current file is in. For example, I want to convert something like example.com/folder/subfolder/file.php to subfolder.
My current code is dirname($_SERVER['PHP_SELF']), but that returns /folder/subfolder instead of subfolder. Thank you!

Answer 1

The simpliest way is:

basename(__DIR__);

Answer 2

You need to combine your existing code using dirname() with a call to basename():

$parent = basename(dirname($_SERVER['PHP_SELF']));
