What are the advantages of using PDO with prepared statements over traditional mysqli functions for database interactions in PHP?

Using PDO with prepared statements offers several advantages over traditional mysqli functions for database interactions in PHP. Prepared statements provide a more secure way to interact with databases by preventing SQL injection attacks. PDO also offers database abstraction, making it easier to switch between different database systems without changing your code. Additionally, PDO supports named parameters, making queries more readable and maintainable. 

// Using PDO with prepared statements for database interactions
try {
    $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    $stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id");
    $stmt->bindParam(':id', $userId, PDO::PARAM_INT);
    $stmt->execute();
    $user = $stmt->fetch();
} catch (PDOException $e) {
    echo "Error: " . $e->getMessage();
}
