title: How to redirect all my urls with no extension to end with .php
body: <p>I originally wanted to have all my urls end with no extension. Unfortunately, I've tried many htaccess codes and I've just about given up.</p>
  
  <p>So now I want to make it so if a person wants to visit a page in my site, but forgets to enter .php, he/she will automatically be redirected to the same url but with the .php </p>
  
  <p>How can this be done? Thanks!</p>
