Millisecond

How do I get system time in milliseconds? Or, simply, I want to record some timing info:

$starttime = millisecond();
.....other codes
$endtime = millisecond();

$timetaken = $endtime - $starttime;

Please help! Thanks!

Look at microtime()

<?php
//get microtime function
function get_microtime()
{ $tmp=split(" ",microtime());
$gettime=$tmp[0]+$tmp[1];
//echo $gettime;
return $gettime;
}

$time_start = get_microtime();

for($i=0; $i<10000; $i++)
{
}

$time_end = get_microtime();
$time_use = $time_end - $time_start;
$time_use = number_format($time_use, 4);
echo $time_use;
?>

You are using a function to get the start time, and that function itself takes time to process.

If you want a more accurate timing, store the time in a var and process it after you got the end_time.
