$config = load_app_config(); // Load the configuration file $db_host = $config['db_host']; // Get the database host from config $db_name = $config['db_name']; // Get the database name from config $db_user = $config['db_user']; // Get the database username from config $db_pass = $config['db_pass']; // Get the database password from config // Connect to the database using the credentials $pdo = new PDO("mysql:host=$db_host;dbname=$db_name", $db_user, $db_pass);
$config = load_app_config(); // Load the configuration file $language = $config['language']; // Get the language setting from config // Load the language file based on the language setting include_once("lang/{$language}.php");Package/Library: It is difficult to determine the package/library from just the function name as load_app_config() could be a custom function created for a specific application. However, similar functions can be found in popular PHP frameworks like Laravel and CodeIgniter.
