title: Why use index.php rather than index.html for point of entry (homepage)?
body: <p>I am developing code in PHP. I am creating a website to demonstrate the scripts that use PHP code.</p>
  
  <p>Can someone explain how to structure this project.</p>
  
  <p>I have many pieces (files) to the puzzle but cannot properly congeal them to work.</p>
  
  <p>Launching <code>index.php</code> display “server not found.”
  Launching <code>index.html</code> displays the correct elements which when clicked correctly navigate to other pages.</p>
  
  <p>My question is asking that someone explain to me logically when the home entry is <code>index.php</code> and when the home entry is <code>index.html</code>?</p>
  
  <p>When I view source from any site it is always and only <code>html</code> code that is visible.</p>
