How to check if the date is exist or not? (with all format)

Question

I want to check a date exist or not with all format PHP like d-m-Y or jS-F-Y or D-M-Y ... ?

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 need to validate against predefined set of formats. You cannot use some formats simultaneously, because you would lose precision - for example 5-6-12 could mean 3 valid dates: 2005-06-12, 05-06-2012, 06-05-2012 (as in May 6th, 2012). — shudder, Jun 08 '18 at 08:54

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
