What are the potential pitfalls of using outdated MySQL functions in PHP scripts?

Using outdated MySQL functions in PHP scripts can lead to security vulnerabilities, compatibility issues with newer versions of MySQL, and deprecated warnings or errors. To solve this issue, it is recommended to use MySQLi (MySQL Improved) or PDO (PHP Data Objects) extensions, which provide better security features, support for prepared statements, and are more compatible with modern PHP and MySQL versions. 

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

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