What are the key differences between server-side PHP scripts and client-side HTML files?

Server-side PHP scripts are processed on the server before being sent to the client's browser, while client-side HTML files are directly interpreted by the browser. PHP scripts can interact with databases, handle form submissions, and perform server-side operations, while HTML files are static and cannot perform dynamic tasks. PHP scripts are executed on the server, which means they are not visible to the end-user, while HTML files are visible to anyone who views the webpage source. 

<?php
// Server-side PHP script example
$variable = "Hello, World!";
echo $variable;
?>
