$settings = new Settings('/path/to/config.ini'); $settings->set('app_name', 'My Cool App');
$settings = new Settings('/path/to/config.ini'); $app_name = $settings->get('app_name');
$settings = new Settings('/path/to/config.ini'); if ($settings->has('app_name')) { // do something }This code creates a new Settings object and checks if the `app_name` key exists. If it does, it executes the code inside the `if` statement. Overall, the Settings class appears to be a standalone package/library for managing configuration files in PHP.
