What are the drawbacks of using the mysql extension in PHP for database operations, and what alternative solutions like mysqli or PDO offer?

The mysql extension in PHP is deprecated and no longer maintained, making it vulnerable to security risks and compatibility issues with newer versions of PHP. To address this, developers should use either the mysqli extension or PDO for database operations, as they offer improved security features, support for prepared statements, and better overall performance. 

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

// Using PDO
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());
}
