Validate Date format mm/dd/yyyy without any Regular Expression

Question

I am trying to validate Date format mm/dd/yyyy with the below code:

**Date is 1st Feb, 2014

$is_valid_date = date('m/d/Y', strtotime('02/01/2014')) == 02/01/2014;

I've tried checking format d-m-Y in above code, it was working fine:

$is_valid_date = date('d-m-Y', strtotime('01-02-2014')) == 01-02-2014;
if( ! $is_valid_date){
    echo 'invalid date';
}

How to do 1 scenario without using any regular expression ??

With dash `-` strtotime assumes date is `dd-mm-yyyy`. With slash `/` it assumes `mm/dd/yyyy`. — AbraCadaver, Jul 29 '14 at 15:44

You could explode by "/" and then validate the date with the function checkdate.

$date = '02/01/2014';
list($month, $day, $year) = explode("/", $date);
$is_valid_date = checkdate($month, $day, $year);

var_dump($is_valid_date);

what if the date format is `02-01-2014`?? Than `explode` will not work... right?? – user3030089 Jul 29 '14 at 15:31
@user3030089 No. My code assumes that you know what separator is being used. – Wayne Whitty Jul 29 '14 at 15:33

make date into string by quotation

<?php
$is_valid_date = date('d/m/Y', strtotime('01-02-2014')) == "01/02/2014";

if(  $is_valid_date){
    echo 'Valid date';
} 
else if ( !$is_valid_date)
{
    echo 'invalid date';
}
?>
