note 83642 added to function.microtime

This function is very useful for putting a start and end point in your page to find out where is the delay. <?php $start = microtime(true); // My source code here $end = microtime(true); echo $end."-".$start."=".($end - $start). " seconds"; ?> If you try this example above (without any source code between the start and the end point). You will get an ugly value, something like: 1212690530.4132-1212690530.4132=8.1062316894531E-6 seconds You will wonder why you get this because both numbers seem to be equal. Well this is because there is a hidden precision that we are not able to see. To solve this problem I made a new function: <?php function my_microtime($precision = 4) { return round(microtime(true),4); } $start = microtime(true); // My source code here $end = microtime(true); echo $end."-".$start."=".substr(($end - $start),0,5). " seconds"; ?> It would be useful if they add another parameter for precision in this function or at least another boolean that will not include the hidden precision.
