What is the best way to communicate data between frames in PHP?

When communicating data between frames in PHP, the best way is to use session variables. By storing the data in session variables, you can easily access and manipulate the data across different frames without having to pass it through URLs or forms. 

// Frame 1
session_start();
$_SESSION['data'] = "Hello from Frame 1";

// Frame 2
session_start();
echo $_SESSION['data']; // Output: Hello from Frame 1
