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

使用php预构建函数的简单方式:

function checkmydate($date) {
  $tempDate = explode('-', $date);
  // checkdate(month, day, year)
  return checkdate($tempDate[1], $tempDate[2], $tempDate[0]);
}

Test

   checkmydate('2015-12-01'); //true
   checkmydate('2015-14-04'); //false

使用checkdate函数验证:

$date = '2019-02-30';

$date_parts = explode( '-', $date );

if(checkdate( $date_parts[1], $date_parts[2], $date_parts[0] )){
    //date is valid
}else{
    //date is invalid
}

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

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);
  }
}

判断字符串是否为日期，即使字符串是非标准格式

(strtotime不接受任何自定义格式)

<?php
function validateDateTime($dateStr, $format)
{
    date_default_timezone_set('UTC');
    $date = DateTime::createFromFormat($format, $dateStr);
    return $date && ($date->format($format) === $dateStr);
}

// These return true
validateDateTime('2001-03-10 17:16:18', 'Y-m-d H:i:s');
validateDateTime('2001-03-10', 'Y-m-d');
validateDateTime('2001', 'Y');
validateDateTime('Mon', 'D');
validateDateTime('March 10, 2001, 5:16 pm', 'F j, Y, g:i a');
validateDateTime('March 10, 2001, 5:16 pm', 'F j, Y, g:i a');
validateDateTime('03.10.01', 'm.d.y');
validateDateTime('10, 3, 2001', 'j, n, Y');
validateDateTime('20010310', 'Ymd');
validateDateTime('05-16-18, 10-03-01', 'h-i-s, j-m-y');
validateDateTime('Monday 8th of August 2005 03:12:46 PM', 'l jS \of F Y h:i:s A');
validateDateTime('Wed, 25 Sep 2013 15:28:57', 'D, d M Y H:i:s');
validateDateTime('17:03:18 is the time', 'H:m:s \i\s \t\h\e \t\i\m\e');
validateDateTime('17:16:18', 'H:i:s');

// These return false
validateDateTime('2001-03-10 17:16:18', 'Y-m-D H:i:s');
validateDateTime('2001', 'm');
validateDateTime('Mon', 'D-m-y');
validateDateTime('Mon', 'D-m-y');
validateDateTime('2001-13-04', 'Y-m-d');
