Why is it advised against using absolute paths in configuration scripts in PHP projects?

Using absolute paths in configuration scripts in PHP projects is advised against because it can make the project less portable. If the project is moved to a different server or directory, the absolute paths may no longer be valid, causing errors. To solve this issue, it is recommended to use relative paths instead, which are based on the current directory structure and will work regardless of the project's location.

// Instead of using absolute paths like this:
// define('CONFIG_PATH', '/var/www/html/config.php');

// Use relative paths like this:
define('CONFIG_PATH', __DIR__ . '/config.php');
