How can the $_GET superglobal array be properly utilized to retrieve variables passed from another PHP script, as demonstrated in the forum thread example?

To properly utilize the $_GET superglobal array to retrieve variables passed from another PHP script, you can access the values by using the key names that were passed in the URL. For example, if a variable "id" is passed in the URL as ?id=123, you can retrieve it in the receiving script using $_GET['id']. This allows you to access and use the passed variables in your PHP script.

// Retrieve the 'id' variable passed from another script
$id = $_GET['id'];

// Use the retrieved variable in your script
echo "The ID passed from the previous script is: " . $id;
