What are the potential pitfalls of using outdated MySQL extensions in PHP, and how can they be addressed?

Using outdated MySQL extensions in PHP can lead to security vulnerabilities, compatibility issues with newer versions of MySQL, and deprecated functionality that may break your application. To address this, it is recommended to switch to MySQLi or PDO extensions, which offer improved security features, support for prepared statements, and better compatibility with modern PHP and MySQL versions. 

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

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

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
