WARNING when using "next month", "last month", "+1 month", "-1 month" or any combination of +/-X months. It will give non-intuitive results on Jan 30th and 31st. As described at : http://derickrethans.nl/obtaining-the-next-month-in-php.html <?php $d = new DateTime( '2010-01-31' ); $d->modify( 'next month' ); echo $d->format( 'F' ), "\n"; ?> In the above, using "next month" on January 31 will output "March" even though you might want it to output "February". ("+1 month" will give the same result. "last month", "-1 month" are similarly affected, but the results would be seen at beginning of March.) The way to get what people would generally be looking for when they say "next month" even on Jan 30 and Jan 31 is to use "first day of next month": <?php $d = new DateTime( '2010-01-08' ); $d->modify( 'first day of next month' ); echo $d->format( 'F' ), "\n"; ?> <?php $d = new DateTime( '2010-01-08' ); $d->modify( 'first day of +1 month' ); echo $d->format( 'F' ), "\n"; ?> ---- Server IP: 69.147.83.197 Probable Submitter: 98.189.138.115 ---- Manual Page -- http://www.php.net/manual/en/function.strtotime.php Edit -- https://master.php.net/note/edit/107331 Del: integrated -- https://master.php.net/note/delete/107331/integrated Del: useless -- https://master.php.net/note/delete/107331/useless Del: bad code -- https://master.php.net/note/delete/107331/bad+code Del: spam -- https://master.php.net/note/delete/107331/spam Del: non-english -- https://master.php.net/note/delete/107331/non-english Del: in docs -- https://master.php.net/note/delete/107331/in+docs Del: other reasons-- https://master.php.net/note/delete/107331 Reject -- https://master.php.net/note/reject/107331 Search -- https://master.php.net/manage/user-notes.php
