What are some best practices for maintaining variable consistency and security when passing data between frames in PHP?

When passing data between frames in PHP, it is important to maintain variable consistency and security to prevent data manipulation or injection. One best practice is to use PHP sessions to store and retrieve data securely across frames. By using session variables, you can ensure that the data passed between frames remains consistent and secure. 

// Start the session
session_start();

// Set data in the session variable
$_SESSION['myData'] = "Hello, World!";

// Retrieve data from the session variable in another frame
echo $_SESSION['myData'];
