Measure duration of a php web request on lighttpd

Question

I'd like to get time (ms) from php request to response for each hit on a page.

Can this be done through lighttpd, or should it be done in php? How?

If done in php, what would be the best performing way of keeping the data so that storing the data does not cost 1/2 of the duration!?

Answer 1

Place this code in first line after open tag PHP:

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

And place this code before closing tag PHP:

$time = explode(" ", microtime());
$time = $time[1] + $time[0];
$endtime = $time;
$totaltime = ($endtime - $begintime);
echo $totaltime.' seconds';

You can store the result in Mysql with 'INSERT DELAYED' for maximum performance.
