为什么要使用正则表达式？使用DateTime类。
function validateDate($date, $format = 'Y-m-d H:i:s'){ $d = DateTime::createFromFormat($format, $date); return $d && $d->format($format) == $date;}您可以将此功能用于所有类型的日期/时间验证。例子：
var_dump(validateDate('2012-02-28 12:12:12')); # truevar_dump(validateDate('2012-02-30 12:12:12')); # falsevar_dump(validateDate('2012-02-28', 'Y-m-d')); # truevar_dump(validateDate('28/02/2012', 'd/m/Y')); # truevar_dump(validateDate('30/02/2012', 'd/m/Y')); # falsevar_dump(validateDate('14:50', 'H:i')); # truevar_dump(validateDate('14:77', 'H:i')); # falsevar_dump(validateDate(14, 'H')); # truevar_dump(validateDate('14', 'H')); # truevar_dump(validateDate('2012-02-28T12:12:12+02:00', 'Y-m-dTH:i:sP')); # true# orvar_dump(validateDate('2012-02-28T12:12:12+02:00', DateTime::ATOM)); # truevar_dump(validateDate('Tue, 28 Feb 2012 12:12:12 +0200', 'D, d M Y H:i:s O')); # true# orvar_dump(validateDate('Tue, 28 Feb 2012 12:12:12 +0200', DateTime::RSS)); # truevar_dump(validateDate('Tue, 27 Feb 2012 12:12:12 +0200', DateTime::RSS)); # false# ...
