Question

I am working on is a website which features:

• user signup
• user login
• add friend/delete friend
• karma
• hotlinks (user can add any page to there nav)
• admin panel (available to admin personnel only)
• user email system

I have created all of these things and they all work how they should. How I can test the php scripts–not the load time of the page, but the actual runtime of each script on each page?

Answer 1

You’ll want to invoke micro time.

At the beginning of your script:

$startTime = microtime( true );

At the end of the script, and be sure to use this variable method or else you may get a negative:

$endTime = microtime( true );
echo( "Time taken: " . ( $endTime - $startTime ) );

To get this time in miliseconds, you can do:

$parseTime = $endTime - $startTime;
$timeTaken = number_format( ( $parseTime * 1000 ), 3 );
echo( $timeTaken . "ms" );

One good way to benchmark is just take a look at the average run time of some of the more popular PHP applications. Many put parse time in the footer.
