With DateTime you can make the shortest date&time validator for all formats.


function validateDate($date, $format = 'Y-m-d H:i:s')
$d = DateTime::createFromFormat($format, $date);
$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

In the example you gave, it is correctly returning false. The function example is comparing a string to a known date format. I suggest reading the documentation on the date format to see why you're making the wrong assumption.

The below suggested date validation (from another note) does NOT work for ALL formats and date inputs.

function validateDate($date, $format = 'Y-m-d H:i:s')
    $d = DateTime::createFromFormat($format, $date);
    return $d && $d->format($format) == $date;

A couple of examples should suffice as a warning to test carefully and particularly not to use code that allows passing in of just any date format string:

var_dump(validateDate('7/01/16', 'n/j/y')); # false but should be true
var_dump(validateDate('7/1/16', 'm/d/y')); # false but should be true

Sorry, I don't have a suggested correction.
