What are common errors when including PHP files and how can they be resolved?

Common errors when including PHP files include using incorrect file paths, missing file extensions, and including files multiple times. To resolve these issues, always use the correct file path, include the file extension (.php), and use include_once or require_once to prevent multiple inclusions. 

// Incorrect file path
include 'path/to/file.php';

// Correct file path
include 'correct/path/to/file.php';
