Pdo V20 | Extended Features
$pdo->pgsqlGetNotify(PDO::FETCH_ASSOC, 5000); // wait 5ms for async notifications $pdo->pgsqlCopyFromArray('table', $data, "\t"); Modern SQLite extensions allow:
// New way: direct enum $status = $stmt->fetch(PDO::FETCH_ENUM); // UserStatus::Active
enum UserStatus: string { case Active = 'active'; case Inactive = 'inactive'; } $stmt = $pdo->prepare("SELECT status FROM users WHERE id = ?"); $stmt->execute([1]); pdo v20 extended features
$pdo = new class($dsn, $user, $pass) extends PDO { private ?PDO $connection = null; private function connect(): void { if (!$this->connection) { $this->connection = new PDO($this->dsn, ...); } }
By adopting these extended features, you write less glue code, catch more bugs at compile time, and achieve better performance. Whether you're building a micro-framework, a legacy migration, or an enterprise API, modern PDO is not what you remember from PHP 5. Modern extended features clean it up
$pdo->exec('PRAGMA journal_mode=WAL'); // concurrency $pdo->exec('CREATE TABLE users (id INT, name TEXT) STRICT'); // strict typing Old PDO had messy error handling. Modern extended features clean it up. 6.1 Exception Subclassing PDO now throws PDOException with richer context:
$repository = new PdoRepository($pdo, User::class); $user = $repository->find(1); $user = $repository->
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING); set_error_handler(function($errno, $errstr, $errfile, $errline, $errcontext) { if (strpos($errstr, 'PDO') !== false) { // Send to logging service } }); PHP 8 attributes allow metadata-driven persistence. While Doctrine ORM does this heavily, a mini "PDO v20" extended ORM can be built:
