如何检查日期是否存在？ （所有格式）

Question

I want to check a date exist or not with all format PHP like dmY or jS-F- Y or DMY ... ?

For example:

01-01-2018 => true
31-02-2018 => false
30 Februari 2018 => false
31st Feb 2018 => false
31st March 2018 => true
31-04-2018 => false

I found this function: checkdate but it only can check date with number format.

You can go through the examples overhere

http://php.net/manual/en/function.checkdate.php

<?php
var_dump(checkdate(12, 31, 2000));
var_dump(checkdate(2, 29, 2001));
?>

The above example will output:

bool(true) bool(false)

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
