Regex pattern for date (ex. August 9, 2011)

Question

I'm new to regex and I'm having problem understanding how to formulate a pattern to a date for example (August 9, 2011)

@BjörnTantau Used DateTime and it worked pretty well. Thanks! — Steven, Sep 04 '17 at 13:04

Regex is not best suited for date validation. Use PHP's built-in function to do so.

You can do it this way:

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

^{function was copied from this answer or php.net}

Use it this way:

var_dump(validateDate('August 9, 2011', 'F j, Y')); # true

You can pass various date format as follows:

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

thanks! tried using the DateTime format and it worked well. – Steven Sep 04 '17 at 12:57 — Steven, Sep 04 '17 at 12:57
