ini_set('intl.default_locale', 'pt_PT');
ini_set('intl.use_exceptions', '1');
$cal = new IntlGregorianCalendar(2013, 6 /* July */, 1);
var_dump(IntlDateFormatter::formatObject($cal), // 01/07/2013, 00:00:00
$cal->isLenient()); // true
$cal->set(IntlCalendar::FIELD_DAY_OF_MONTH, 33);
var_dump(IntlDateFormatter::formatObject($cal)); // 02/08/2013, 00:00:00
$cal->setLenient(false);
var_dump($cal->isLenient()); // false
$cal->set(IntlCalendar::FIELD_DAY_OF_MONTH, 33);
var_dump(IntlDateFormatter::formatObject($cal)); // error
