Question

say i have a file /var/www/foo/test.php

how do i find out it’s path from within it. i’m trying to create an ‘Add To Include Path’ action, and for that i need absolute paths.

Answer 1

Note: I am leaving my original answer intact, but don’t use it. The solutions involving the __FILE__ constant are preferred.

You can use $_SERVER['DOCUMENT_ROOT'] to find the path to the current script. If you need the name of the .php file included, add on $_SERVER['SCRIPT_NAME'], like this:

$_SERVER['DOCUMENT_ROOT'].$_SERVER['SCRIPT_NAME'];
