Benchmark or time script

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

<?php
// a function to  get microtimefunction getmicrotime(){
  list($usec, $sec) = explode(" ",microtime());
  return ((float)$usec + (float)$sec);
}
// start time$time_start = getmicrotime();
// a little loop to timefor ($i=0; $i < 10000; $i++)
{// print the loop numberecho $i.'<br />';
}
// the end time$time_end = getmicrotime();
// subtract the start time from the end time to get the time taken$time = $time_end - $time_start;

// echo a little messageecho '<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.
