PHP require_once issue

I just successfully troubleshot an issue I had with my PHP code to having nested require_once commands and am wondering the proper way to handle this issue. This is the file structure:

Index calls header and footer php files. header.php calls head.php and nav.php. When all of the files have require_once code for my global variable config.php file, index does not display.

Each of the files need the global variables in order to properly link. Can I call the config file in the index and have it trickle down to the nested files? I have changed the code to include, but I think I recall from the video that require_once is a better code choice for global variables.

Hi Ted,

Yes, that is 100% possible. All you need to do is require your config file before your header file and the variables will be passed along as PHP executes scripts from top-to-bottom.

Hope that helps.
