In my MySQL based page I perform series of database queries in very simple manner, not thinking about optimizing. I'd like to measure execution time of this piece of code on server side to detect whether non-optimized code is slowing my page or not.

How do I do it in PHP?

Many service-provider offer "benchmarks" for PHP-scripts.

You can do it by yourselft in the following way:

3 pieces of code:


1: take the start time:

$start = microtime();


2: take the end time:

$end = microtime();


3: calculate the difference and echo it:

$start = explode(" ",$start);
$end = explode(" ",$end);
$diff = ($end[0] + $end[1]) - ($start[0] + $start[1]);

echo $diff;



Put the first part before the code you wanna test.
Put the second part after the code you wanna test.
Put the third part after the second part (so the calculation istn counted).

The Value you get is the "execution time" between the $start and the $end in seconds (so for short scripts its normal to get something like "0.00004324234").


Hope that helps, Panther :)

Thanks! My script takes 0.1 s on average -- quite fast.
