title: What is the file extension .PHPS? And what is it used for?
body: <p>I'm doing an online challenge where I have to log on to a server with a username and password. I inspected element and found a comment in the HTML code saying that the details are in 'page.phps' in case he forgets the details. So I was wondering: what's the difference between <code>.php</code> and <code>.phps</code>?</p>
