What are the potential risks of using deprecated MySQL functions in PHP scripts?

Using deprecated MySQL functions in PHP scripts can lead to security vulnerabilities, compatibility issues, and potential errors in the future. It is recommended to switch to MySQLi or PDO functions for database interactions to ensure better security and future-proofing of your code. 

// Deprecated MySQL function
mysql_query("SELECT * FROM users");

// Updated MySQLi function
$mysqli = new mysqli("localhost", "username", "password", "database");
$result = $mysqli->query("SELECT * FROM users");
