Pdo V20 Extended Features -

foreach ($stmt->paginate(50, 'created_at') as $page) foreach ($page as $row) process($row);

$pool = new PDOConnectionPool('mysql:host=db;dbname=app', 'user', 'pass', [ 'min_connections' => 5, 'max_connections' => 20, 'idle_timeout' => 60 ]); $pdo = $pool->getConnection(); // Use $pdo normally, then $pool->release($pdo); This is NOT a separate library—it's built into the extended driver stack for PHP 8.4+. One of the most overlooked performance boosters is the bulk operation feature. Instead of looping and re-preparing statements, you can now batch inserts/updates in one round-trip. Example: Bulk Insert $data = [ ['john@example.com', 'John'], ['jane@example.com', 'Jane'], // ... 10,000 rows ]; $stmt = $pdo->prepare("INSERT INTO users (email, name) VALUES (?, ?)"); $stmt->bulkExecute($data, PDO::BULK_IGNORE_DUPLICATES); // Single network round-trip, 10,000 rows inserted. pdo v20 extended features

Lazy Connection & Statement Introspection PDO v20 extended features introduce true lazy connections . Previously, new PDO() immediately connected to the database, consuming resources. Now, you can defer connection until the first query. Example: Bulk Insert $data = [ ['john@example
