intlcal_create_instance([mixed $timeZone= NULL[,string $locale= ""]]): IntlCalendar
Given a timezone and locale, this method creates an IntlCalendar object. This factory method may return a subclass of IntlCalendar.
The calendar created will represent the time instance at which it was created, based on the system time. The fields can all be cleared by calling IntCalendar::clear() with no arguments. See also IntlGregorianCalendar::__construct().
参数
- $timeZone
The timezone to use.
NULL
, in which case the default timezone will be used, as specified in the ini setting date.timezone or through the function date_default_timezone_set() and as returned by date_default_timezone_get().An IntlTimeZone, which will be used directly.
A DateTimeZone. Its identifier will be extracted and an ICU timezone object will be created; the timezone will be backed by ICUʼs database, not PHPʼs.
A string, which should be a valid ICU timezone identifier. See IntlTimeZone::createTimeZoneIDEnumeration(). Raw offsets such as"GMT+08:30"are also accepted.
- $locale
A locale to use or
NULL
to use the default locale.
返回值
The created IntlCalendar instance or NULL
on failure.
范例
IntlCalendar::createInstance()
<?php ini_set('intl.default_locale', 'es_ES'); ini_set('date.timezone', 'Europe/Madrid'); $cal = IntlCalendar::createInstance(); echo "No arguments\n"; var_dump(get_class($cal), IntlDateFormatter::formatObject($cal, IntlDateFormatter::FULL)); echo "\n"; echo "Explicit timezone\n"; $cal = IntlCalendar::createInstance(IntlTimeZone::getGMT()); var_dump(get_class($cal), IntlDateFormatter::formatObject($cal, IntlDateFormatter::FULL)); echo "\n"; echo "Explicit locale (with calendar)\n"; $cal = IntlCalendar::createInstance(NULL, 'es_ES@calendar=persian'); var_dump(get_class($cal), IntlDateFormatter::formatObject($cal, IntlDateFormatter::FULL));
以上例程会输出:
No arguments string(21) "IntlGregorianCalendar" string(68) "martes 18 de junio de 2013 14:11:02 Hora de verano de Europa Central" Explicit timezone string(21) "IntlGregorianCalendar" string(45) "martes 18 de junio de 2013 12:11:02 GMT+00:00" Explicit locale (with calendar) string(12) "IntlCalendar" string(70) "martes 28 de Khordad de 1392 14:11:02 Hora de verano de Europa Central"
