What are the benefits of transitioning from the mysql extension to mysqli or PDO in PHP for database interactions?

The mysql extension in PHP is deprecated and no longer maintained, leaving security vulnerabilities and compatibility issues. Transitioning to either mysqli or PDO provides improved security features, support for prepared statements, and compatibility with newer versions of PHP. 

// Using mysqli extension to connect to a database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
