    示例

    示例 #1 datefmt_set_calendar() example

    <?php
    $fmt     = datefmt_create(
    'en_US',
    IntlDateFormatter::FULL,
    IntlDateFormatter::FULL,
    'America/Los_Angeles',
    IntlDateFormatter::GREGORIAN
    );
    echo     'calendar of the formatter is : ' . datefmt_get_calendar($fmt);
    datefmt_set_calendar($fmt, IntlDateFormatter::TRADITIONAL);
    echo     'Now calendar of the formatter is : ' . datefmt_get_calendar($fmt);
    ?>

    示例 #2 OO example

    <?php
    $fmt     = new IntlDateFormatter(
    'en_US',
    IntlDateFormatter::FULL,
    IntlDateFormatter::FULL,
    'America/Los_Angeles',
    IntlDateFormatter::GREGORIAN
    );
    echo     'calendar of the formatter is : ' . $fmt->getCalendar();
    $fmt->setCalendar(IntlDateFormatter::TRADITIONAL);
    echo     'Now calendar of the formatter is : ' . $fmt->getCalendar();
    ?>

    以上示例会输出：

    calendar of the formatter is : 1
Now calendar of the formatter is : 0

    示例 #3 Example with IntlCalendar argument

    <?php
    $time     = strtotime("2013-03-03 00:00:00 UTC");
    $formatter = IntlDateFormatter::create("en_US", NULL, NULL, "Europe/Amsterdam");

    echo     "before: ", $formatter->format($time), "\n";

    /* note that the calendar's locale is not used! */
    $formatter->setCalendar(IntlCalendar::createInstance(
    "America/New_York", "pt_PT@calendar=islamic"));

    echo     "after: ", $formatter->format($time), "\n";

    以上示例会输出：

    before: Sunday, March 3, 2013 at 1:00:00 AM Central European Standard Time
after:  Saturday, Rabiʻ II 20, 1434 at 7:00:00 PM Eastern Standard Time
