IntlCalendar::isLenient()
<?php ini_set('date.timezone', 'Europe/Lisbon'); 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
以上例程会输出:
