I am using php version 5.4.24 and I can't use the class DateInterval.
I get this error: PHP Fatal error: Class 'DateInterval' not found
$interval = new DateInterval('P91D');
What should I do in order to make this code work?
You need to add the following class in the Controllers. Also make sure your php version (PHP 5 >= 5.3.0, PHP 7)
use DateTime;
use DatePeriod;
use DateInterval;
class DashboardController extends Controller
{
}
