Have you used PHP Data Objects (PDO) in your projects?

Yes, I have used PHP Data Objects (PDO) in projects for database interaction. PDO provides a unified interface for accessing different database management systems and supports prepared statements, which enhance security and ease of use.

Main advantages of PDO:

• Support for prepared statements, preventing SQL injection.
• Versatility — you can change the database driver without changing the code.
• Convenient methods for executing queries and retrieving results.

Example of using PDO:

$pdo = new PDO('mysql:host=localhost;dbname=testdb', 'user', 'password');
$stmt = $pdo->prepare('SELECT * FROM users WHERE email = :email');
$stmt->execute(['email' => $email]);
$user = $stmt->fetch(PDO::FETCH_ASSOC);

Thus, PDO is a reliable and flexible way to interact with a database in PHP.
