note 101971 added to function.date-diff

I use this much simpler solution: function dateDifference($firstDate, $lastDate) { $firstTime = strtotime($firstDate); $lastTime = strtotime($lastDate); $diff = round(($lastTime - $firstTime) / 86400); return $diff; } I've tested this using all of the cases I could think of: - dates inside DST - dates outside DST - dates overlapping the start of DST - dates overlapping the end of DST - dates during a leap year - dates during a non-leap year Am I missing something that the other more complicated solutions are accounting for? ---- Server IP: 69.147.83.197 Probable Submitter: 98.210.216.87 ---- Manual Page -- http://www.php.net/manual/en/function.date-diff.php Edit -- https://master.php.net/note/edit/101971 Del: integrated -- https://master.php.net/note/delete/101971/integrated Del: useless -- https://master.php.net/note/delete/101971/useless Del: bad code -- https://master.php.net/note/delete/101971/bad+code Del: spam -- https://master.php.net/note/delete/101971/spam Del: non-english -- https://master.php.net/note/delete/101971/non-english Del: in docs -- https://master.php.net/note/delete/101971/in+docs Del: other reasons-- https://master.php.net/note/delete/101971 Reject -- https://master.php.net/note/reject/101971 Search -- https://master.php.net/manage/user-notes.php
