title: PHP changes not showing on local
body: <p>I am using OSX Yosemite and I have installed MAMP. I am able to upload my files to htdocs and view them on the localhost:8888, however when I make changes to a php file, the changes won't show up, only the original content of the php file remains. </p>
  
  <p>The original file says:
  and I see in the localhost : 8888
     Hello World.
  However, when changing it to the following:
  -- --
  the localhost still prints:
     Hello World!
  and not the changes to Hello Everyone!!! as the code specifies.</p>
  
  <p>Can you please help,
  Thanks!</p>
