How does the usage of server-side scripting in PHP differ from client-side scripting like JavaScript when it comes to gathering client information?

Server-side scripting in PHP allows you to gather client information by processing data on the server before sending a response back to the client. This means that sensitive information can be securely handled on the server side without exposing it to the client. In contrast, client-side scripting like JavaScript runs on the client's browser, making it less secure for handling sensitive data. 

<?php
// Retrieve client information using server-side scripting in PHP
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$ip_address = $_SERVER['REMOTE_ADDR'];

echo "User Agent: " . $user_agent . "<br>";
echo "IP Address: " . $ip_address;
?>
