With DateTime you can make the shortest date&time validator for all formats. <?php function validateDate($date, $format = 'Y-m-d H:i:s') { $d = DateTime::createFromFormat($format, $date); return $d && $d->format($format) == $date; } var_dump(validateDate('2012-02-28 12:12:12')); # true var_dump(validateDate('2012-02-30 12:12:12')); # false var_dump(validateDate('2012-02-28', 'Y-m-d')); # true var_dump(validateDate('28/02/2012', 'd/m/Y')); # true var_dump(validateDate('30/02/2012', 'd/m/Y')); # false var_dump(validateDate('14:50', 'H:i')); # true var_dump(validateDate('14:77', 'H:i')); # false var_dump(validateDate(14, 'H')); # true var_dump(validateDate('14', 'H')); # true var_dump(validateDate('2012-02-28T12:12:12+02:00', 'Y-m-d\TH:i:sP')); # true # or var_dump(validateDate('2012-02-28T12:12:12+02:00', DateTime::ATOM)); # true var_dump(validateDate('Tue, 28 Feb 2012 12:12:12 +0200', 'D, d M Y H:i:s O')); # true # or var_dump(validateDate('Tue, 28 Feb 2012 12:12:12 +0200', DateTime::RSS)); # true var_dump(validateDate('Tue, 27 Feb 2012 12:12:12 +0200', DateTime::RSS)); # false # ... ---- Server IP: 69.147.83.199 Probable Submitter: 92.63.27.15 ---- Manual Page -- http://php.net/manual/en/function.checkdate.php Edit -- https://master.php.net/note/edit/113205 Del: integrated -- https://master.php.net/note/delete/113205/integrated Del: useless -- https://master.php.net/note/delete/113205/useless Del: bad code -- https://master.php.net/note/delete/113205/bad+code Del: spam -- https://master.php.net/note/delete/113205/spam Del: non-english -- https://master.php.net/note/delete/113205/non-english Del: in docs -- https://master.php.net/note/delete/113205/in+docs Del: other reasons-- https://master.php.net/note/delete/113205 Reject -- https://master.php.net/note/reject/113205 Search -- https://master.php.net/manage/user-notes.php
