PHP require_once error with relative path

Question

I would like to test my php application in phpunit. My problem is the require_once doesn't find the file what I would like to test. I get this error:

Warning:
require_once(C:\MyProject\phpunit-tesztek\include/../include/form.php):
failed to open stream: No such file or directory in
C:\MyProject\phpunit-tesztek\include\FormTest.php on line 4

So it search the form.php file in include/../include/form.php what is wrong.

I used this code:

require_once 'PHPUnit/Autoload.php';
require_once(__DIR__.'/../include/form.php');

the Test file is in C:\MyProject\phpunit-tesztek\include\FormTest.php

and the file what I want to test is in: C:\MyProject\include\form.php

What is the problem?

The problem is that the path you want to required ("C:\MyProject\include\form.php") does not match the path you specify: "C:\MyProject\phpunit-tesztek\include/../include/form.php". It should become clear from the error message, can you see it? See as well the answer by Steven Scott. — hakre

The problem is the relative path. The __DIR__ uses the directory the file is in without a trailing separator. You are then changing the path with a relative path (/../) to go up one directory.

See the manual entry -> PHP Manual for __DIR__

__DIR__ will return C:\MyProject\phpunit-tesztek\include

You are looking to use the C:\MyProject\include\ path

__DIR__ . '/../../include/Form.php';

I normally use the dirname(__FILE__) myself, as it gets the current directory of the source code file (which is absolute) allowing my relative path to move from that location.

dirname(__FILE__) is the outdated way to write exactly __DIR__ which was introduced in PHP 5.3 and not available earlier. It btw. was introduced to spare dirname() calls. Just FYI :)

@hakre Thanks for the FYI. I have references to the old, as 5.2 was still in use in areas, and for some of the team, it is a little clearer that you are getting the directory of what is passed. While DIR is the script's directory, you can use dirname() on another variable to retrieve its path as well.\

Try removing ../

require_once(DIR.'include/form.php');

Use magic constant DIR :

require_once(__DIR__ . '/../include/form.php');
