php include_once not working for only one file

Question

I have two folders Provider and Library in the same directory. Provider includes two php files ActiveRequests.php and PendingRequests.php . Library contains another folder Multilingual which includes Pagefactory.php and languageSession.php

- Provider
  - ActiveRequests.php
  - PendingRequests.php
- Library
  - Multilingual
    - Pagefactory.php
    - languageSession.php

I'm including PageFactory.php in ActiveRequests.php like

      include_once __DIR__ . '/../library/Multilingual/PageFactory.php'

and it is working fine.

But when I'm trying to include PageFactory.php in PendingRequests.php in the same way like

       include_once __DIR__ . '/../library/Multilingual/PageFactory.php'

it is not working.

when I tried to include the languageSession.php in Pendingrequests.php like

       include_once __DIR__ . '/../library/Multilingual/languageSession.php'

it is working fine.

Can any one help me? What could be the problem with the PageFactory.php path?

I've also tried with $_SERVER["DOCUMENT_ROOT"] but it did not work.

Answer 1

I've just fix a same problem, the point is if you include PageFactory.php in PendingRequests.php you have to change every file that PageFactory.php refers base on PendingRequests.php path. I fixed my problem with this way.

Answer 2

Try printing the path as

echo __DIR__ . '/../library/Multilingual/PageFactory.php';

In this way, you can check if the path to the file is correct!

Or use, var_dump to check the path!

To The people downvoting my answer: Printing the path is for debugging!

Or you can check the path as :

var_dump(file_exists(__DIR__ . '/../library/Multilingual/PageFactory.php'));

__DIR__ is the path to the parent directory. It gives path of Provider when used from PendingRequests.php .

I think the problem is you have used ../ .Try removing it!

For example, __DIR__ . '/../library/Multilingual/PageFactory.php' __DIR__ . '/../library/Multilingual/PageFactory.php' is identical to

path/to/Provider/../library/Multilingual/PageFactory.php

So the final answer is to remove "../" and it becomes:

__DIR__ . '/library/Multilingual/PageFactory.php'

Answer 3

The obvious problem is that you include the file with the following:

include_once __DIR__ . '/../library/Multilingual/PageFactory.php'

While the file is called Pagefactory.php .

On non-Windows systems, this will make a difference. Ensure that the capitalisation is correct.

This may just be a typo in your question (the amount of typos in it originally would suggest it could be!) but it may be the cause of the problem.
