How can PHP files access configuration files in different directories?

To access configuration files in different directories, you can use the `include` or `require` functions in PHP to include the configuration file in your PHP script. You can specify the full path to the configuration file or use relative paths based on the current working directory. Make sure to handle any errors that may occur if the file is not found or if there are permission issues. 

// Include configuration file using full path
include('/path/to/config.php');

// Include configuration file using relative path
include('../config/config.php');
