Question

Update:

The index.php file here:

/public_html/d/index.php

includes:

/public_html/d/core/source/class.File1.php

This Class.File1.php here has this include written like this:

include 'class.File2.php';

Naturally I put class.File2.php in the same directory as class.File1.php as noted above.

/public_html/d/core/source/class.File2.php

However,

It actually includes this file: ( notice the missing /d/ )

/public_html/core/source/class.File2.php

Not sure why it doesn’t use the file that is in the current directory.

But here are some possibilities.

Entry from a user requesting the page comes in to: ( user types www.host.com/d )

/public_html/d/

This has an include to: ( which works fine, I tested it )

/public_html/d/core/source/class.File1.php 

However the include in that file is where things break as noted above:

include "class.File2.php"

The only thing that makes sense…is that includes are using some sort of internal constant like

ROOT

or

$_SERVER['DOCUMENT_ROOT']

but I still can’t figure out why it would ignore the /d/ but figure out the rest.

Answer 1

Are you using set_include_path anywhere in your app? Perhaps that could be the cause of your problem. By doing that you are specifying a list of directories where the require, include, fopen(), file(), readfile() and file_get_contents() functions look for files first.

As an alternative I suggest you define the absolute path to avoid problems.
Write this on your /public_html/d/core/source/class.File1.php

// This if you are using PHP >= 5.3
include(__DIR__ . '/class.File2.php');

// Or this if you dont have the magic constant __DIR__ available
include(dirname(__FILE__) . '/class.File2.php');

__FILE__ and __DIR__ are magic constants. __FILE__ is a constant that has the absulute path to that specific file. And __DIR__ is the absulte path to the directory where that file is. You can even test them by doing echo __FILE__; or echo __DIR__;
