      <TD><?php
       include_once ("statusfileon.php")         
  ?></TD> 
       <TD><?php 
             include_once ("statusfileoff.php")         
  ?></td>

    PHP is executed by the server before the HTML is served up. So it isn’t like clicking the buttons is calling your PHP function.

    In this case, statusfileon() is executed and right afterwards, statusfileoff() is executed and then the page is served to your browser. Button clicks aren’t doing anything.

    To execute the code, you might want to redirect the user to statusfileon.php or statusfileoff.php on click of the button using an HTML link if you want the behaviour you are looking for.
