$fmt = datefmt_create(
    'en_US',
    IntlDateFormatter::FULL,
    IntlDateFormatter::FULL,
    'America/Los_Angeles',

$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();
?>

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";
