Example #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);
?>
Example #2 OO example

IntlDateFormatter::GREGORIAN
);
echo 'calendar of the formatter is : ' . $fmt->getCalendar();
$fmt->setCalendar(IntlDateFormatter::TRADITIONAL);

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