Previous Comments: ------------------------------------------------------------------------ [2015-12-31 19:13:19] ruben at solunapilates dot es Hi, Yes, your workaround works, but the right behaviour must be "if 31/11 doesn't exist, show a month before" because we are trying to get "a month before" (-1 month), is not? ------------------------------------------------------------------------ [2015-12-31 14:10:12] bwoebi@php.net That just happens on months with more days than previous month on the last day. December 31 - 1 month = November 31 => December 1 Better try date('F',strtotime('first day of last month')), which will give you what you expect. ------------------------------------------------------------------------ [2015-12-31 11:56:42] ruben at solunapilates dot es Description: ------------ In day 31 of December, the function date('F',strtotime('- 1 month')); returns "December" instead November. Happens all months Test script: --------------- $today=date('F',strtotime('- 1 month')); print($today); Expected result: ---------------- November Actual result: -------------- December ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71255&edit=1
