What are the potential security risks of using register_globals in PHP scripts, and how can developers mitigate these risks?

Using register_globals in PHP scripts can lead to security vulnerabilities such as injection attacks and unauthorized variable manipulation. Developers can mitigate these risks by disabling register_globals in the php.ini configuration file and using superglobal arrays like $_GET, $_POST, and $_COOKIE to access user input securely. 

// Disable register_globals in php.ini
// Use superglobal arrays to access user input securely
$username = $_POST['username'];
$password = $_POST['password'];
