IntlCalendar::createInstance — Create a new IntlCalendar
面向对象风格
$timezone = null, ?string $locale = null): ?IntlCalendar
过程化风格
$timezone = null, ?string $locale = null): ?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().
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.
The created IntlCalendar instance or null on
failure.
示例 #1 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"
