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

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

to display the output.

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;

Howdy,

Just wanted to say thanks for this article, I used it to test the difference between a single MySQL call and a file being picked up locally. The difference was amazing Local file storage was 6-7 faster!!!!

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 :)

I time all my programs and log the timing to a file to help me tune my database system. I have developed a class to help.

<?php
/**
 * Time Code Class
  * @author Russell Thompson
 */
class pgmTiming
{
      private $mtime;
      public function __construct()  {
          $this->mtime = microtime(true);
      }
      public function  __destruct()  {
           $pgmName = $_SERVER["SCRIPT_NAME"];
           print ("tm: " . $pgmName . " " . (microtime(true) -
              this->mtime));
     }
}

in my programs, after I make sure the class is loaded (I depend on __autoload) All I need is one line.

$tm = new pgmTiming();

As part of php cleanup, the destructor will run and print out the timing. I have the instantiation statement in a require_once file.

In the example above it just prints the result. My actual destructor writes to a log file so I can average timings.
