What are the potential pitfalls of using absolute path declarations in PHP code within the Xampp environment?

Using absolute path declarations in PHP code within the Xampp environment can lead to issues when moving the code to a different server or directory structure. To avoid this, it's recommended to use relative paths instead. This way, the code will be more portable and easier to maintain.

// Incorrect absolute path declaration
include 'C:/xampp/htdocs/project/includes/config.php';

// Correct relative path declaration
include 'includes/config.php';
