You can use __DIR__
to get your current script's directory. It has been in PHP only since version 5.3, and it's the same as using dirname(__FILE__)
. In most cases it is used to include another file from an included file.
Consider having two files in a directory called inc
, which is a subfolder of our project's directory, where the index.php
file lies.
project
├── inc
│?? ├── file1.php
│?? └── file2.php
└── index.php
If we do include "inc/file1.php";
from index.php
it will work. However, from file1.php
to include file2.php
we must do an include relative to index.php and not from file1.php
(so, include "inc/file2.php";
). __DIR__
fixes this, so from file1.php
we can do this:
<?php
include __DIR__ . "/file2.php";
To answer your question: to include the file warlock.php
that is in your included file's upper directory, this is the best solution:
<?php
include __DIR__ . "/../warlock.php";
