title: Pagination in PHP
body: <p>I have a page that serves a list of files for users to download.
  There can be hundreds of files there, and I would like to break them down into multiple pages and give users the option either to see them page by page or get them all displayed in one page.
  I've never done anything like this and don't know how to do it.</p>
  
  <p>Please help.
  Thank you!</p>
