    $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;

      Here’s the stripped down version of daGrevis’ fine work:


      $startTime = array_sum(explode(' ', microtime()));

      /* Your code here */

      $totalTime = array_sum(explode(' ', microtime())) - $startTime;
      echo $totalTime;

    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 :)
