How can values be passed between frames in PHP?

Values can be passed between frames in PHP by using sessions or cookies. Sessions store data on the server side and can be accessed across multiple pages, while cookies store data on the client side. To pass values between frames, you can set the values in a session or cookie in one frame and retrieve them in another frame. 

// Frame 1
session_start();
$_SESSION['value'] = 'Hello, World!';

// Frame 2
session_start();
if(isset($_SESSION['value'])){
    $value = $_SESSION['value'];
    echo $value;
}
