How can PHP developers ensure that their scripts can be easily opened and run by new users without the need to adjust file paths?

PHP developers can ensure that their scripts can be easily opened and run by new users without the need to adjust file paths by using the `__DIR__` magic constant to get the absolute path of the current file. This way, file paths within the script can be defined relative to the current file's location, making the script more portable and easier to use. 

// Define file paths relative to the current file's location using __DIR__
include __DIR__ . '/includes/config.php';
require_once __DIR__ . '/classes/User.php';
