What are the recommendations for transitioning from the mysql extension to mysqli or PDO_MySQL extension in PHP for database operations?

The mysql extension in PHP is deprecated and no longer supported, so it is recommended to transition to either the mysqli or PDO_MySQL extension for database operations. This will ensure compatibility with newer versions of PHP and improve the security of your application. 

// Using mysqli extension
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Using PDO_MySQL extension
$pdo = new PDO("mysql:host=localhost;dbname=database", "username", "password");

if (!$pdo) {
    die("Connection failed");
}
