how can I check if a variable type is DateTime

How can I check if a variable is a datetime type on php, please? I've tried this, but it seems doesn't work.

public function setRegistrationDate ($registrationDate) {

   if (!is_date($registrationDate, "dd/mm/yyyy hh:mm:ss")) {
       trigger_error('registrationDate != DateTime', E_USER_WARNING);
       return;
   }

   $this->_registrationDate = $registrationDate;
}

I think this way is more simple:

if (is_a($myVar, 'DateTime')) ...

This expression is true if $myVar is a PHP DateTime object.

Since PHP 5, this can be further simplified to:

if ($myVar instanceof DateTime) ...

function validateDate($date, $format = 'Y-m-d H:i:s')
{
    $d = DateTime::createFromFormat($format, $date);
    return $d && $d->format($format) == $date;
}

The simplest answer is : to check with strtotime() function

$date = strtotime($datevariable);

If it's valid date, it will return timestamp, otherwise returns FALSE.

I would use the following method:

public function setRegistrationDate ($registrationDate) {
  if(!($registrationDate instanceof DateTime)) {
    $registrationDate = date_create_from_format("dd/mm/yyyy hh:mm:ss", $registrationDate)
  }

  if(!($registrationDate instanceof DateTime)) {
    trigger_error('registrationDate is not a valid date', E_USER_WARNING);
    return false;
  }

  $this->_registrationDate = $registrationDate;
  return true
}
