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
