intl

  • MessageFormatter::format 及其相关函数现在 related functions now accept named arguments and mixed numeric and named arguments when PHP is linked to ICU 4.8 or later.
  • MessageFormatter::format and related functions no longer error when an insufficient number of arguments have been provided. Instead, the placeholders will not be substituted.
  • MessageFormatter::format and MessageFormatter::parse are no longer limited to second precision when dealing with times.
  • IntlDateFormatter::__construct and datefmt_create now accept IntlTimeZone and DateTimeZone objects for the timezone argument, and IntlCalendar objects for the calendar argument. Furthermore, if the time zone is omitted and the calendar doesn't specify a time zone, PHP's default time zone from date_default_timezone_get is now used instead of the default ICU time zone.
  • IntlDateFormatter::getCalendar and datefmt_get_calendar return false if the IntlDateFormatter object was created with an IntlCalendar instance instead of one of the IntlDateFormatter constants.
  • IntlDateFormatter 常量之外, IntlDateFormatter::setCalendardatefmt_set_calendar现在接受 IntlCalendar 对象。
  • IntlDateFormatter::formatdatefmt_format 现在接受 IntlCalendar 对象。
