使用php包含层次结构中不同级别的文件

Question

I am creating a browser/text-based game. In order to organize the files, I broke them down into different folders

Game

Server //DB Connection Files
Styles //CSS Files
Structure //Any Template files for the viewable pages (menu bars, etc that I don't want to copy in each viewable .php**
Scripts //JS Files
Location Folders // Like 'Work' or 'Crime' - the menu options

If I'm in say localhost/game/work/work.php and want to access the database, I would have to use

include "../../server/dbc.php";

I have tried

$root = dirname(__file__);

in my localhost/game folder before, but it started giving me an error - "failed to open stream: no suitable wrapper could be found" which is because it's using a full file location and you apparently can't do that.

Is there an easier way to make it so I can access my DB from anywhere regardless of hierarchy in the folders?

Thank you in advance!

There are a many options, I'll provide a few in order of ease of implementation:

• Leverage $_SERVER['DOCUMENT_ROOT']
• Append your app source path to the PHP include path
• Define a constant (like APP_PATH) in a bootstrap/config file
• Read about autoloading in PHP and PSR-4
