Question: Below is how I previously verified dates. I also had my own functions to convert date formats, however, now am using PHP's DateTime class so no longer need them. How should I best verify a valid date using DataTime? Please also let me know whether you think I should be using DataTime in the first place. Thanks

PS. I am using Object oriented style, and not Procedural style.

```
static public function verifyDate($date)
{
  //Given m/d/Y and returns date if valid, else NULL.
  $d=explode('/',$date);
  return ((isset($d[0])&&isset($d[1])&&isset($d[2]))?(checkdate($d[0],$d[1],$d[2])?$date:NULL):NULL);
}

```

Answer: 
You could check this resource: <http://php.net/manual/en/datetime.getlasterrors.php>

The PHP codes states:

```
try {
    $date = new DateTime('asdfasdf');
} catch (Exception $e) {
    print_r(DateTime::getLastErrors());
    // or
    echo $e->getMessage();
}

```
I needed to allow user input in (n) different, known, formats...including microtime. Here is an example with 3.

```
function validateDate($date)
{
    $formats = ['Y-m-d','Y-m-d H:i:s','Y-m-d H:i:s.u'];
    foreach($formats as $format) {
        $d = DateTime::createFromFormat($format, $date);
        if ($d && $d->format($format) == $date) return true;
    }
    return false;
}

```
