日本做黄视频网站有哪些开发一个平台需要多少钱

在网上看了这么多解答，还是php官网的这种方法一最好用，感谢glavic at gmail dot com

但是官网的方法只适合PHP>5.3的，对于比较低级的版本会出现错误：Call to undefined method DateTime::createfromformat()

解决方法一：

解决方法二：

function checkDatetime($str, $format="Y-m-d H:i:s"){

$unixTime=strtotime($str);

$checkDate= date($format, $unixTime);

if($checkDate==$str)

return 1;

else

return 0;

}

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);

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
