IntlDateFormatter::format -- datefmt_format — Format the date/time value as a string

설명

객체 기반 형식

public string IntlDateFormatter::format ( mixed $value )

절차식 형식

string datefmt_format ( IntlDateFormatter $fmt , mixed $value )

Formats the time value as a string.

인수

fmt

The date formatter resource.

value

Value to format. This may be a DateTime object, an IntlCalendar object, a numeric type representing a (possibly fractional) number of seconds since epoch or an array in the format output by localtime().

If a DateTime or an IntlCalendar object is passed, its timezone is not considered. The object will be formatted using the formaterʼs configured timezone. If one wants to use the timezone of the object to be formatted, IntlDateFormatter::setTimeZone() must be called before with the objectʼs timezone. Alternatively, the static function IntlDateFormatter::formatObject() may be used instead.

반환값

The formatted string or, if an error occurred, FALSE.

변경점

버전 설명
5.5.0/PECL 3.0.0 Support for providing IntlCalendar objects to the value parameter was added.
5.3.4 Support for providing DateTime objects to the value parameter was added.
