How to Calculate PHP Load Times
Here’s a popular request amongst those who are learning PHP. When developing PHP applications, it’s good practice to benchmark your pages to see if you need to further optimize your code. The following snippet will show you how much time it took your server to process your PHP document.
Insert this at or near the top of your PHP file.
$m_time = explode(" ",microtime());
$m_time = $m_time[0] + $m_time[1];
$loadstart = $m_time;
$m_time = $m_time[0] + $m_time[1];
$loadstart = $m_time;
Now place this snippet at or near the bottom of your file for the best results.
$m_time = explode(" ",microtime());
$m_time = $m_time[0] + $m_time[1];
$loadend = $m_time;
$loadtotal = ($loadend - $loadstart);
echo "<small><em>Generated page in ". round($loadtotal,3) ." seconds</em></small>";
$m_time = $m_time[0] + $m_time[1];
$loadend = $m_time;
$loadtotal = ($loadend - $loadstart);
echo "<small><em>Generated page in ". round($loadtotal,3) ." seconds</em></small>";
That’s it! I suggest adding this while you develop any PHP application, and include it even after the launch, so that you can see how well your scripts scale with the traffic you receive.
If you click the link in my name, that is the timer function I always use to calculate. Makes it really nice and easy!
