What are the risks associated with using object names for session storage in PHP?

Using object names for session storage in PHP can pose a security risk as it can potentially allow for object injection attacks. To mitigate this risk, it is recommended to always sanitize and validate user input before storing it in the session.

// Sanitize and validate user input before storing in session
$userInput = filter_input(INPUT_POST, 'user_input', FILTER_SANITIZE_STRING);

// Store sanitized input in session
$_SESSION['user_input'] = $userInput;
