Why is it recommended to switch to PDO and Prepared Statements in PHP for security?

Using PDO and Prepared Statements in PHP is recommended for security because it helps prevent SQL injection attacks. Prepared Statements separate SQL code from user input, ensuring that input is treated as data and not executable code. PDO also provides a more secure and consistent way to interact with databases, making it easier to switch between different database systems. 

// Using PDO and Prepared Statements to query a database securely
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $_POST['username']);
$stmt->execute();

$results = $stmt->fetchAll();
foreach ($results as $row) {
    // Process the results
}
