What is the purpose of passing variables between PHP scripts using GET without requiring a link to be clicked?

When passing variables between PHP scripts using GET without requiring a link to be clicked, the purpose is typically to transfer data between different pages or scripts seamlessly without user interaction. This can be useful for maintaining state across multiple pages or for passing data between different parts of an application. 

// Script 1: Setting the variable in the URL
$variable = "Hello World";
$url = "script2.php?var=" . urlencode($variable);
header("Location: $url");

// Script 2: Retrieving the variable from the URL
$received_variable = urldecode($_GET['var']);
echo $received_variable; // Output: Hello World
