What is the significance of using dirname(__FILE__) in PHP?

Using `dirname(__FILE__)` in PHP is significant because it allows you to get the directory path of the current PHP file, regardless of where it is located in the file system. This is useful when including files or referencing resources within the same directory or in a relative path. It ensures that your code remains portable and independent of the file's location on the server. 

// Get the directory path of the current PHP file
$directory = dirname(__FILE__);

// Use the $directory variable to include files or reference resources
include($directory . '/config.php');
