PDO v20 style can hydrate enums automatically, eliminating manual validation. Using PDO::FETCH_INT and PDO::FETCH_FLOAT ensures type-safety:
readonly class UserRepository { public function __construct(private PDO $pdo) { $this->pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $this->pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC); } public function findActiveByRole(string $role): array { $sql = "SELECT id, status FROM users WHERE role = ? AND status = 'active'"; $stmt = $this->pdo->prepare($sql); $stmt->execute([$role]); return $stmt->fetchAll(PDO::FETCH_OBJ); // modern stdClass usage } pdo v20 extended features
$stmt = $pdo->prepare("SELECT * FROM users WHERE email = :email AND status = ?"); $stmt->execute([':email' => 'a@b.com', 1]); // works! While not native, modern tooling like pdo-debug extends PDO with query analysis: PDO v20 style can hydrate enums automatically, eliminating
public function getColumnMetaInfo(string $table): array { $stmt = $this->pdo->query("SELECT * FROM {$table} LIMIT 0"); for ($i = 0; $i < $stmt->columnCount(); $i++) { $meta[] = $stmt->getColumnMeta($i); } return $meta; } } The phrase "PDO v20 extended features" captures the evolution of PHP’s database layer from a simple abstraction into a modern, type-safe, and high-performance toolkit. While no official "PDO 2.0" exists, the accumulated enhancements across PHP 8.x—enums, attributes, new fetch modes, driver-specific optimizations, and better error handling—offer a dramatically improved developer experience. While not native, modern tooling like pdo-debug extends
