试着让我知道这对我有用

$date = \DateTime::createFromFormat('d/m/Y', $dataRowValue);
if (!empty($date)) {
//Your logic
}else{
//Error
}

如果您传递任何alpha或字母数字值，它将返回给您空值

你可以使用DateTime::createFromFormat()来实现这个目的:

function validateDate($date, $format = 'Y-m-d')
{
    $d = DateTime::createFromFormat($format, $date);
    // The Y ( 4 digits year ) returns TRUE for any integer with any number of digits so changing the comparison from == to === fixes the issue.
    return $d && $d->format($format) === $date;
}

[从这个答案中得到的函数。在php.net上也有。原作者:格拉维克。

测试用例:

var_dump(validateDate('2013-13-01'));  // false
var_dump(validateDate('20132-13-01')); // false
var_dump(validateDate('2013-11-32'));  // false
var_dump(validateDate('2012-2-25'));   // false
var_dump(validateDate('2013-12-01'));  // true
var_dump(validateDate('1970-12-01'));  // true
var_dump(validateDate('2012-02-29'));  // true
var_dump(validateDate('2012', 'Y'));   // true
var_dump(validateDate('12012', 'Y'));  // false

正则表达式的解决方案

function verify_date($date){
  /* correct format = "2012-09-15 11:23:32" or "2012-09-15"*/
  if (preg_match("/^[0-9]{4}-(0[1-9]|1[0-2])-(0[1-9]|[1-2][0-9]|3[0-1])( (0[0-9]|[1-2][0-4]):(0[0-9]|[1-5][0-9]):(0[0-9]|[1-5][0-9]))?$/",$date)) {
    return true;
  } else {
    die("Wrong date format: it should be '2012-09-15 11:23:32' or '2012-09-15', date received is: ".$date);
  }
}
