Edit report at http://bugs.php.net/bug.php?id=25050&edit=1 ID: 25050 Updated by: pajoye@php.net Reported by: tlii_php at bsb dot cz Summary: mktime(); and gmmktime(); using "xx" parameter Status: Bogus Type: Bug Package: Date/time related Operating System: Linux PHP Version: 4.3.2 New Comment: bugs.php.net is not a support channel, read http://en.wikipedia.org/wiki/Octal_number if you need more details about octal numbers. Previous Comments: ------------------------------------------------------------------------ [2010-04-03 14:37:22] enabled at yandex dot ru Then why vardump(4==04) is true? ------------------------------------------------------------------------ [2003-08-12 04:32:35] derick@php.net 08 does not exist, because the octal number 8 doesn't exist. If you prefix a number with a 0 it marks the number as octal, and because in some cases a number doesnt exist you get weird output. This is not a bug -> bogus. ------------------------------------------------------------------------ [2003-08-12 04:23:00] tlii_php at bsb dot cz Description: ------------ When is for mktime(); used month parameter in form "xx", then in some cases it appears to produce incorrect output ( timestamp ). Same situation in gmmktime(); Reproduce code: --------------- $test1 = mktime(22,00,00,07,01,2003); $test2 = mktime(22,00,00,08,01,2003); $test3 = mktime(22,00,00,8,01,2003); $test4 = mktime(22,00,00,09,01,2003); $test5 = mktime(22,00,00,9,01,2003); $test6 = mktime(22,00,00,10,01,2003); $test7 = gmmktime(22,00,00,8,01,2003); $test8 = gmmktime(22,00,00,08,01,2003); echo date("j.m.Y H:i", $test1 )." -- mktime(22,00,00,07,01,2003); <br>"; echo date("j.m.Y H:i", $test2 )." -- mktime(22,00,00,08,01,2003); <br>"; echo date("j.m.Y H:i", $test3 )." -- mktime(22,00,00,8,01,2003); <br>"; echo date("j.m.Y H:i", $test4 )." -- mktime(22,00,00,09,01,2003); <br>"; echo date("j.m.Y H:i", $test5 )." -- mktime(22,00,00,9,01,2003); <br>"; echo date("j.m.Y H:i", $test6 )." -- mktime(22,00,00,10,01,2003); <br><br>"; echo date("j.m.Y H:i", $test7 )." -- gmmktime(22,00,00,8,01,2003); <br>"; echo date("j.m.Y H:i", $test8 )." -- gmmktime(22,00,00,08,01,2003); "; Actual result: -------------- 1.07.2003 22:00 -- mktime(22,00,00,07,01,2003); 1.12.2002 22:00 -- mktime(22,00,00,08,01,2003); 1.08.2003 22:00 -- mktime(22,00,00,8,01,2003); 1.12.2002 22:00 -- mktime(22,00,00,09,01,2003); 1.09.2003 22:00 -- mktime(22,00,00,9,01,2003); 1.10.2003 22:00 -- mktime(22,00,00,10,01,2003); 2.08.2003 00:00 -- gmmktime(22,00,00,8,01,2003); 1.12.2002 23:00 -- gmmktime(22,00,00,08,01,2003); ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=25050&edit=1
