I've got a universal solution that will work in any PHP file inside the wp-content folder without any adjustments or needing to know what is mysterious 'path/to/wordpress'

require_once(explode("wp-content", __FILE__)[0] . "wp-load.php");

It just automatically goes up to root of WordPress and loads wp-load.php.

You can just paste it anywhere, no matter if it's a plugin or theme file, and it will work.

I think stuff like ../../../.. looks extremely bad and when you modify the structure of your folders of a theme or plugin you can get crazy.

Note: This solution assumes you didn't rename your wp-content folder.
