How can PHP developers ensure proper variable scope and accessibility when passing data between scripts within the same application?

To ensure proper variable scope and accessibility when passing data between scripts within the same application, PHP developers can use sessions or cookies to store and retrieve data across different script executions. By using these methods, developers can maintain data persistence and accessibility throughout the application. 

// Script 1
session_start();
$_SESSION['data'] = "Hello, World!";

// Script 2
session_start();
echo $_SESSION['data']; // Output: Hello, World!
