note 114968 added to function.max

max() (and min()) on DateTime objects compares them like dates (with timezone info) and returns DateTime object. <?php $dt1 = new DateTime('2014-05-07 18:53', new DateTimeZone('Europe/Kiev')); $dt2 = new DateTime('2014-05-07 16:53', new DateTimeZone('UTC')); echo max($dt1,$dt2)->format(DateTime::RFC3339) . PHP_EOL; // 2014-05-07T16:53:00+00:00 echo min($dt1,$dt2)->format(DateTime::RFC3339) . PHP_EOL; // 2014-05-07T18:53:00+03:00 ?> It works at least 5.3.3-7+squeeze17 ---- Server IP: 62.149.26.211 Probable Submitter: 91.202.75.190 ---- Manual Page -- http://php.net/manual/en/function.max.php Edit -- https://master.php.net/note/edit/114968 Del: integrated -- https://master.php.net/note/delete/114968/integrated Del: useless -- https://master.php.net/note/delete/114968/useless Del: bad code -- https://master.php.net/note/delete/114968/bad+code Del: spam -- https://master.php.net/note/delete/114968/spam Del: non-english -- https://master.php.net/note/delete/114968/non-english Del: in docs -- https://master.php.net/note/delete/114968/in+docs Del: other reasons-- https://master.php.net/note/delete/114968 Reject -- https://master.php.net/note/reject/114968 Search -- https://master.php.net/manage/user-notes.php
