title: PHP: Is there a reason to put a newline at the end of file
body: <p>When I commit a php file to github I get the message "No newline at end of file".</p>
  
  <p>It's just a warning and I remember, that for any reason it is good to have a newline at the end of a file.</p>
  
  <p>But why? Is it a remnant of long gone times, does it still have advantages or is it even required in php? If yes, for what reason?</p>
