What considerations should be made when restructuring the file inclusion concept in PHP to avoid link display issues?

When restructuring the file inclusion concept in PHP to avoid link display issues, it is important to ensure that the paths to the included files are correct and consistent. Using absolute paths or defining a base path can help in avoiding any display problems due to incorrect file paths. Additionally, using the `dirname(__FILE__)` function can help in getting the current directory path dynamically.

// Define base path
define('BASE_PATH', dirname(__FILE__) . '/');

// Include file using absolute path
include BASE_PATH . 'included_file.php';
