How does PHP handle include statements with or without parentheses?

PHP can handle include statements with or without parentheses. Including a file without parentheses is the traditional way of including files in PHP. However, including a file with parentheses is a more modern and recommended approach as it makes the code more readable and maintainable. Both methods work in PHP, but using parentheses is considered a best practice. 

// Including a file without parentheses
include 'file.php';

// Including a file with parentheses
include('file.php');
