How can PHP beginners effectively use include() or require() to access external files?

PHP beginners can effectively use include() or require() to access external files by specifying the file path correctly. It is important to use the correct file path relative to the current file or absolute path. This allows the PHP script to include the content of the external file seamlessly. 

// Including an external file using require
require 'path/to/external/file.php';

// Including an external file using include
include 'path/to/external/file.php';
