Doc #63878 [NEW]: date time function issue problem

From: rupesh dot php at gmail dot com Operating system: PHP version: Irrelevant Package: *General Issues Bug Type: Documentation Problem Bug description:date time function issue problem Description: ------------ --- From manual page: http://www.php.net/function.date#refsect1-function.date-seealso --- The date time related functions do not work properly when the current date is 31st of a month, like today is 31st December 2012.. It seems to be working on a 30 day principle for a month and does not return the desired output whenever we you a +/- 1month ting with strtotime() function or with a mktime() function. The issue is depicted in the script mentioned below with the output that I get. Script :: --------- for($i=0; $i<6; $i++) { echo date("Y-M-d", mktime(0, 0, 0, date("m")-$i, date("d"), date("Y")))."<br>"; // or even with // echo date("Y-M-d", strtotime("-".$i."day"))."<br>"; } Outputs :: ---------- 2012-Dec-31 2012-Dec-01 2012-Oct-31 2012-Oct-01 2012-Aug-31 2012-Jul-31 instead, it should have been :: ------------- 2012-Dec-31 2012-Nov-30 2012-Oct-31 2012-Sep-30 2012-Aug-31 2012-Jul-31 Note that I have only come across this issue with today being 31st of the month. Test script: --------------- for($i=0; $i<6; $i++) { echo date("Y-M-d", mktime(0, 0, 0, date("m")-$i, date("d"), date("Y")))."<br>"; // or even with // echo date("Y-M-d", strtotime("-".$i."day"))."<br>"; } Expected result: ---------------- 2012-Dec-31 2012-Nov-30 2012-Oct-31 2012-Sep-30 2012-Aug-31 2012-Jul-31 Actual result: -------------- 2012-Dec-31 2012-Dec-01 2012-Oct-31 2012-Oct-01 2012-Aug-31 2012-Jul-31 -- Edit bug report at https://bugs.php.net/bug.php?id=63878&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63878&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63878&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63878&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63878&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63878&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63878&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63878&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63878&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63878&r=support Expected behavior: https://bugs.php.net/fix.php?id=63878&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63878&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63878&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63878&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63878&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63878&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63878&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63878&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63878&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63878&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63878&r=mysqlcfg
