PHP include path sub-folder files not included

I have a site where the PHP include path is /usr/share/php Within this path I have a sub-folder containing some utility files, e.g. /usr/share/php/utils. my_session.php is one of these utility files.

My application calls 

require ("my_session.php");

and this works even though the file is actually within the utils folder.

I am trying to replicate this site in another installation and I am getting the error:

Failed opening required 'my_session.php' (include_path='.:/usr/share/php)

My question is:

Should the php include path also include files in sub-folders in the include path? This appears to be the case on my original site and I don't know why the behaviour seems to be different on the second site.

My guess would be that this fails because you are using a relative path for the require.

Your include_path is defined as .:/usr/share/php. That means only two folders will be checked when require('my_session.php') gets executed:

  • the current path
  • the folder /usr/share/php

I don't know your folder structure, so let's just imagine one:

my_project
- app
-- index.php
- lib
-- my_session.php

Now, if my_project/app/index.php tries to require('my_session.php') this will fail, because the current folder at the time executing the require is my_project/app/ and there is no file entry of my_session.php relative to my_project/app/ (it's relative to my_project/lib/ instead).

Long story short: Try to to use an absolute path instead of your relative one, e.g.

require('/var/www/html/my_project/lib/my_session.php');

Edit: removed and its subfolders, which was wrong. Too much __autoload in my brain^^

Two solutions:

Add /usr/share/php/utils to your include_path.

or

Include your file with require ("utils/my_session.php");

According to PHP documentation when you try to include a file, only paths listed in the include_path directive are checked. PHP is not supposed to check their subfolders.
