Bug #54582 [Opn->Bgs]: Division is not preferred to substraction

Edit report at http://bugs.php.net/bug.php?id=54582&edit=1 ID: 54582 Updated by: rasmus@php.net Reported by: fs at coresec dot de Summary: Division is not preferred to substraction -Status: Open +Status: Bogus Type: Bug Package: Math related Operating System: Debian Squeeze PHP Version: 5.3SVN-2011-04-21 (snap) Block user comment: N Private report: N New Comment: You might want to rethink your code there :) time()/60*60*24 is going to give you the approximate number of days since 1970 which is a bit over 15000. your strtotime() is going to return the number of seconds since 1970. Then you subtract the number of days from the number of seconds? That makes no sense, but PHP is doing exactly what you are asking for. You should be using http://php.net/datetime for stuff like this anyway, not timestamps.

Test script: --------------- $remaining = floor(strtotime(str_replace('-','',$mysql[6])) - time()/(60*60*24)); Expected result: ---------------- 29 Actual result: -------------- 1305920914 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54582&edit=1
