<!-- put this at the top of the page --> 

<?php 

      $mtime = microtime(); 

      $mtime = explode(' ', $mtime); 

      $mtime = $mtime[1] + $mtime[0]; 

      $starttime = $mtime; 

?> 



<!-- put other code and html in here --> 





<!-- put this code at the bottom of the page --> 

<?php 

      $mtime = microtime(); 

      $mtime = explode(" ", $mtime); 

      $mtime = $mtime[1] + $mtime[0]; 

      $endtime = $mtime; 

      $totaltime = ($endtime - $starttime); 

      echo 'This page was created in ' .$totaltime. ' seconds.';
