What is the difference between GET parameters in a request and a response in PHP?

In PHP, GET parameters are used to pass data from the client to the server in the URL. These parameters are accessed using the $_GET superglobal array in PHP. On the other hand, in a response, you typically do not use GET parameters as they are meant for passing data from the client to the server. 

// Example of accessing GET parameters in a request
if(isset($_GET['param'])){
    $paramValue = $_GET['param'];
    echo "Value of param: " . $paramValue;
}

// Example of sending a response without using GET parameters
echo "Response without using GET parameters";
