  ["timezone_type"]=>
  int(3)

  string(13) "Europe/Berlin"
}

how to access the key "date" from the above, Thank you

You can access the date value in two different ways.

Number one: Use __toString()

echo $var->__toString();
// or
echo (string)$var;

Number two: Use the DateTime format method:

echo $var->format('Y-m-d H:i:s');
