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

Edit report at https://bugs.php.net/bug.php?id=63878&edit=1 ID: 63878 Comment by: mail+php at requinix dot net Reported by: rupesh dot php at gmail dot com Summary: date time function issue problem Status: Open Type: Documentation Problem Package: *General Issues PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Take a close look at the documentation for mktime(). day The number of the day relative to the end of the previous month. [...] Values greater than the number of days in the relevant month reference the appropriate day in the following month(s). When you told it to create a time for "November 31st, 2012" it overflowed the day number into December. Same for September/October. Likewise if you had it go all the way back to February it would have given you March 2nd.

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 this bug report at https://bugs.php.net/bug.php?id=63878&edit=1
