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

Answer 1

str_replace('/','',$_SERVER[REQUEST_URI]);

This works for php7: str_replace('/','',$_SERVER["REQUEST_URI"]);

Result:

lib/**images**/index.php

images

Answer 2

$folder = basename(dirname(__FILE__));

Answer 3

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

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

Answer 4

dirname() used with basename() would work ... also this if you want to get them all:

$folders = explode ('/', $_SERVER['PHP_SELF']);

Now $folders would contain an array of all of the folder names.

Cheers.

Answer 5

The simpliest way is:

basename(__DIR__);
