What are the advantages of using mysqli or PDO over the deprecated mysql extension in PHP for database interactions?

The deprecated mysql extension in PHP is no longer supported and poses security risks due to lack of prepared statement support, making it vulnerable to SQL injection attacks. To address this, developers should use either the mysqli or PDO extensions, which provide more secure and modern ways to interact with databases, including support for prepared statements and parameterized queries. 

// Using mysqli extension
$mysqli = new mysqli('localhost', 'username', 'password', 'database');
if ($mysqli->connect_error) {
    die('Connection failed: ' . $mysqli->connect_error);
}

// Using PDO extension
try {
    $pdo = new PDO('mysql:host=localhost;dbname=database', 'username', 'password');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
    die('Connection failed: ' . $e->getMessage());
}
