note 116227 added to datetime.add

Here is a solution to adding months when you want 2014-10-31 to become 2014-11-30 instead of 2014-12-01. <?php /** * Class MyDateTime * * Extends DateTime to include a sensible addMonth method. * * This class provides a method that will increment the month, and * if the day is greater than the last day in the new month, it * changes the day to the last day of that month. For example, * If you add one month to 2014-10-31 using DateTime::add, the * result is 2014-12-01. Using MyDateTime::addMonth the result is * 2014-11-30. */ class MyDateTime extends DateTime { public function addMonth($num = 1) { $date = $this->format('Y-n-j'); list($y, $m, $d) = explode('-', $date); $m += $num; while ($m > 12) { $m -= 12; $y++; } $last_day = date('t', strtotime("$y-$m-1")); if ($d > $last_day) { $d = $last_day; } $this->setDate($y, $m, $d); } } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 173.164.31.73 ---- Manual Page -- http://php.net/manual/en/datetime.add.php Edit -- https://master.php.net/note/edit/116227 Del: integrated -- https://master.php.net/note/delete/116227/integrated Del: useless -- https://master.php.net/note/delete/116227/useless Del: bad code -- https://master.php.net/note/delete/116227/bad+code Del: spam -- https://master.php.net/note/delete/116227/spam Del: non-english -- https://master.php.net/note/delete/116227/non-english Del: in docs -- https://master.php.net/note/delete/116227/in+docs Del: other reasons-- https://master.php.net/note/delete/116227 Reject -- https://master.php.net/note/reject/116227 Search -- https://master.php.net/manage/user-notes.php
