note 70877 added to function.microtime

I've noticed when running microtime() for the first time, there is a bit of a delay (v 5.1.4). Try this: <?php function stuff() { $t1 = microtime(true); $t2 = microtime(true); echo sprintf('%.6f', ($t2 - $t1) ) . "\r\n"; } //microtime(); stuff(); stuff(); stuff(); ?> The first result will probably be a little higher. I get: 0.000004 0.000001 0.000001 Then try calling microtime() just once before the stuff()s. The first run will drop by a bit. Don't forget sprint() can format your numbers. ---- Server IP: 66.163.161.117 Probable Submitter: 74.118.124.47 ---- Manual Page -- http://www.php.net/manual/en/function.microtime.php Edit -- https://master.php.net/note/edit/70877 Del: integrated -- https://master.php.net/note/delete/70877/integrated Del: useless -- https://master.php.net/note/delete/70877/useless Del: bad code -- https://master.php.net/note/delete/70877/bad+code Del: spam -- https://master.php.net/note/delete/70877/spam Del: non-english -- https://master.php.net/note/delete/70877/non-english Del: in docs -- https://master.php.net/note/delete/70877/in+docs Del: other reasons-- https://master.php.net/note/delete/70877 Reject -- https://master.php.net/note/reject/70877 Search -- https://master.php.net/manage/user-notes.php
