Php Include() Issues [closed]

Answer 1

I'm struggling slightly to understand your question. I think your file structure looks like this:

• users.php
• test (folder)
  • main.php
  • auth.php
  • db.php

If so, to include db.php from main.php, all you need do is include('db.php');. The current folder is automatically in the path used to determine which files might be included.

In auth.php, you do include('../test/main.php');. This is unnecessary, since you are already in the test folder. You do .. to get out of it, then you go straight back into it! You can simplify this with include('main.php');.

Answer 2

Includes are always relative to the working directory (actually, relative to the PATH, of which the working directory is a part). The working directory is determined by the script that's being executed. Say you have this structure:

webroot/
    foo.php
    folder/
        bar.php

When you run foo.php either through $ php foo.php on the command line or by visiting localhost/foo.php in your browser, the working directory is webroot/. If you run folder/bar.php, the working directory is webroot/folder.

To make sure you're including files relative to the file the include is in, use something like:

include __DIR__ . '/folder/bar.php`;

That, or alter your PATH to add your project root to it and always include relative to the project root. I prefer either file relative includes as shown above or autoloading though.
