   $execution_time = sprintf(‘It took %.5f sec’, $execution_time);
   echo $execution_time;

   # or

   printf(‘It took %.5f sec’, $execution_time);

   # to display the output.

   This technique will not work correctly!
   I would suggest something like this…

   
$time = microtime();
$time = explode(' ', $time);
$time = $time[1] + $time[0];
$start = $time;

   // Your code.

   $time = microtime();
$time = explode(' ', $time);
$time = $time[1] + $time[0];
$finish = $time;

   $page_time = ($finish - $start);
$page_time = round($page_time, 3); // For users.

   echo $page_time;

   Since php 5.1, the timestamp of the start of the request is available in $_SERVER['REQUEST_TIME']

   So you can do :

   $page_time = round(microtime(true)-$_SERVER['REQUEST_TIME'], 3);

   Perhaps “register_shutdown_function()” could be of some use here :)
