checkdate() 공개 정적인 메소드

Checks the validity of the date formed by the arguments. A date is considered valid if each parameter is properly defined. works like php's built in checkdate() function. Leap years are taken into consideration. e.g: $obj->checkdate(10, 21, 1390); // Return true $obj->checkdate(9, 31, 1390); // Return false You can force gregorian checkdate if system default is jalali and you need to check based on gregorian date $check = $obj->checkdate(12, 31, 2011, false);
