What are best practices for securely storing form data in PHP sessions?

When storing form data in PHP sessions, it is important to ensure that the data is securely stored to prevent unauthorized access or tampering. One best practice is to serialize the form data before storing it in the session to prevent direct access to the raw data. Additionally, you should validate and sanitize the form data before storing it in the session to prevent any malicious input. 

// Validate and sanitize form data
$form_data = $_POST['form_data'];

// Serialize the form data before storing in session
$serialized_data = serialize($form_data);

// Store the serialized data in the session
$_SESSION['form_data'] = $serialized_data;
