Timing Script Execution - Page 3

by: Allan Kent

September 26, 2000

My PHP script to use this object now looks like this:




<?php



include ('phptimer.inc');

$timer = new PHP_timer;

$timer->start();

$timer->addmarker('marker 1');

$timer->stop();

$timer->debug();

$timer->showtime();



?>

and will return to me something like:

Script execution debug information:

Marker	Time	Diff
Start	968594548.36899100	-
here be marker 1	968594548.36970100	0.000710
Stop	968594548.37014500	0.000444

0.001154

Last Word

I've intended this script to be a quick and easy way for programmers to debug lock ups and timing problems in their scripts. Therefore I haven't included any error checking code. Also use a bit of common sense about where you put markers in your code - inside a loop that is iterating through a database is probably not a good idea. Once before and one after the loop would be a better idea.

I have started working on some ways of improving the debug information and output with graphs and being able to nest or group markers, but this should be a start on debugging your scripts.
