note 110359 added to function.microtime

it happens due to time changes... try this instead of your script: for ($i = 0; $i < 1000000; $i++) { if (($t = time()) < floor($f = microtime(true))) { echo "Time=$t Microtime=$f Iteration=$i<br>".PHP_EOL; } } you till see that where it says "Iteration", it will start in a big number and then every single number after it will be +1 the initial... it MIGHT stop the +1 count and start again with another huge number... this is because the time is different, and it takes a bit longer to do those iterations, so, it will be bigger, the microtime... since the microtime has .xxx, it will be higher... for example: 5 and 5.000001 5.000001 is higher... test here: http://writecodeonline.com/php/ and here: http://phptester.net/index.php?lang=en don't test here: http://sandbox.onlinephpfunctions.com/ ---- Server IP: 69.147.83.199 Probable Submitter: 95.136.43.99 ---- Manual Page -- http://www.php.net/manual/en/function.microtime.php Edit -- https://master.php.net/note/edit/110359 Del: integrated -- https://master.php.net/note/delete/110359/integrated Del: useless -- https://master.php.net/note/delete/110359/useless Del: bad code -- https://master.php.net/note/delete/110359/bad+code Del: spam -- https://master.php.net/note/delete/110359/spam Del: non-english -- https://master.php.net/note/delete/110359/non-english Del: in docs -- https://master.php.net/note/delete/110359/in+docs Del: other reasons-- https://master.php.net/note/delete/110359 Reject -- https://master.php.net/note/reject/110359 Search -- https://master.php.net/manage/user-notes.php
