How can PHP scripts on the server calculate variables and make them available for use in other scripts?

To calculate variables on the server with PHP and make them available for use in other scripts, you can use sessions or cookies to store the calculated variables and retrieve them in other scripts. Sessions are preferred for sensitive data as they are stored on the server, while cookies are stored on the client's browser. 

// Calculate a variable
$number1 = 10;
$number2 = 5;
$sum = $number1 + $number2;

// Store the calculated variable in a session
session_start();
$_SESSION['sum'] = $sum;

// Retrieve the calculated variable in another script
session_start();
$sum = $_SESSION['sum'];
echo "The sum is: " . $sum;
