How to run a function 1000 times and return microtime() of how long it took?

Question

I want to performance test a couple of php functions. What is the easiest approach to repeat code 1000 times and return how long it took all together via microtime()?

Maybe a repeated loop? I came across a very simple code here on SO recently but forgot to favorite it.

i know without looking the manual page for microtome has many examples — , Mar 05 '15 at 01:35

What's so difficult about it? Let's modify this example from PHP Manual

<?php
$time_start = microtime(true);

$times=0;               // This couldn't be tough
while($times<1000)
{
   yourFunction();
   $times++;
}


$time_end = microtime(true);
$time = $time_end - $time_start;

echo "Did yourFunction in $time seconds\n";
?>
