Here is a little example of how to benchmark or time something with php

<?php

// a function to  get microtime
function getmicrotime(){
  list(
$usec$sec) = explode(" ",microtime());
  return ((float)
$usec + (float)$sec);
}

// start time
$time_start getmicrotime();

// a little loop to time
for ($i=0$i 10000$i++)
{
// print the loop number
echo $i.'<br />';
}

// the end time
$time_end getmicrotime();

// subtract the start time from the end time to get the time taken
$time $time_end $time_start;


// echo a little message
echo '<br />Script ran for ' round($time,2) .' seconds.';

?>

This will produce a list of numbers from 0 to 9999 in your browser and tell you how long it took too complete the iterations.
