note 115270 added to datetime.createfromformat

I've found that on PHP 5.5.13 (not sure if it happens on other versions) if you enter a month larger than 12 on a format that takes numeric months, the result will be a DateTime object with its month equal to the number modulo 12 instead of returning false. <?php var_dump(DateTime::createFromFormat('Y-m-d', '2013-22-01')); ?> results in: class DateTime#4 (3) { public $date => string(19) "2014-10-01 13:05:05" public $timezone_type => int(3) public $timezone => string(3) "UTC" } ---- Server IP: 72.52.91.14 Probable Submitter: 125.252.71.190 ---- Manual Page -- http://php.net/manual/en/datetime.createfromformat.php Edit -- https://master.php.net/note/edit/115270 Del: integrated -- https://master.php.net/note/delete/115270/integrated Del: useless -- https://master.php.net/note/delete/115270/useless Del: bad code -- https://master.php.net/note/delete/115270/bad+code Del: spam -- https://master.php.net/note/delete/115270/spam Del: non-english -- https://master.php.net/note/delete/115270/non-english Del: in docs -- https://master.php.net/note/delete/115270/in+docs Del: other reasons-- https://master.php.net/note/delete/115270 Reject -- https://master.php.net/note/reject/115270 Search -- https://master.php.net/manage/user-notes.php
