locale
Locale to use when formatting or parsing or NULL to use the value
specified in the ini setting intl.default_locale.
datetype
Date type to use (none, short,
medium, long,
full). This is one of the IntlDateFormatter
constants. It can also be NULL, in which case ICU?s default
date type will be used.
timetype
Time type to use (none, short,
medium, long,
full). This is one of the IntlDateFormatter
constants. It can also be NULL, in which case ICU?s default
time type will be used.
timezone
Time zone ID. The default (and the one used if NULL is given) is the
one returned by date_default_timezone_get() or, if
applicable, that of the IntlCalendar object passed
for the calendar parameter. This ID must be a
valid identifier on ICU?s database or an ID representing an
explicit offset, such as GMT-05:30.
This can also be an IntlTimeZone or a DateTimeZone object.
calendar
Calendar to use for formatting or parsing. The default value is NULL,
which corresponds to IntlDateFormatter::GREGORIAN.
This can either be one of the
IntlDateFormatter
calendar constants or an IntlCalendar. Any
IntlCalendar object passed will be clone; it will
not be changed by the IntlDateFormatter. This will
determine the calendar type used (gregorian, islamic, persian, etc.) and,
if NULL is given for the timezone parameter,
also the timezone used.
pattern
Optional pattern to use when formatting or parsing. Possible patterns are documented at » http://userguide.icu-project.org/formatparse/datetime.
The created IntlDateFormatter or FALSE in case of
failure.

Example #1 datefmt_create() example
<?php
$fmt = datefmt_create( "en_US" ,IntlDateFormatter::FULL, IntlDateFormatter::FULL,
'America/Los_Angeles', IntlDateFormatter::GREGORIAN );
echo "First Formatted output is ".datefmt_format( $fmt , 0);
$fmt = datefmt_create( "de-DE" ,IntlDateFormatter::FULL, IntlDateFormatter::FULL,
'America/Los_Angeles',IntlDateFormatter::GREGORIAN );
echo "Second Formatted output is ".datefmt_format( $fmt , 0);
$fmt = datefmt_create( "en_US" ,IntlDateFormatter::FULL, IntlDateFormatter::FULL,
'America/Los_Angeles',IntlDateFormatter::GREGORIAN ,"MM/dd/yyyy");
echo "First Formatted output with pattern is ".datefmt_format( $fmt , 0);
$fmt = datefmt_create( "de-DE" ,IntlDateFormatter::FULL, IntlDateFormatter::FULL,
'America/Los_Angeles',IntlDateFormatter::GREGORIAN ,"MM/dd/yyyy");
echo "Second Formatted output with pattern is ".datefmt_format( $fmt , 0);
?>
Example #2 OO example
<?php
$fmt = new IntlDateFormatter( "en_US" ,IntlDateFormatter::FULL, IntlDateFormatter::FULL,
'America/Los_Angeles',IntlDateFormatter::GREGORIAN );
echo "First Formatted output is ".$fmt->format(0);
$fmt = new IntlDateFormatter( "de-DE" ,IntlDateFormatter::FULL, IntlDateFormatter::FULL,
'America/Los_Angeles',IntlDateFormatter::GREGORIAN );
echo "Second Formatted output is ".$fmt->format(0);
$fmt = new IntlDateFormatter( "en_US" ,IntlDateFormatter::FULL, IntlDateFormatter::FULL,
'America/Los_Angeles',IntlDateFormatter::GREGORIAN ,"MM/dd/yyyy");
echo "First Formatted output with pattern is ".$fmt->format(0);
$fmt = new IntlDateFormatter( "de-DE" ,IntlDateFormatter::FULL, IntlDateFormatter::FULL,
'America/Los_Angeles',IntlDateFormatter::GREGORIAN , "MM/dd/yyyy");
echo "Second Formatted output with pattern is ".$fmt->format(0);
?>
以上例程会输出：
First Formatted output is Wednesday, December 31, 1969 4:00:00 PM PT
Second Formatted output is Mittwoch, 31. Dezember 1969 16:00 Uhr GMT-08:00
First Formatted output with pattern is 12/31/1969
Second Formatted output with pattern is 12/31/1969

Documentation says "timezone: Time zone ID, default is system default."
The "system default" really means only the "TZ" environment variable on Unix/Linux systems. It does not mean PHP ini setting or value set via date_default_timezone_set() or the OS default time zone in file "/etc/timezone".

It should be noted that the locale string passed into IntlDateFormatter's constructor supports UCA keywords. So you can, for example, do things like this to output the year as a Japanese era year:
<?php
$now = new DateTime(); //DateTime is a core PHP class as of version 5.2.0
$formatter = new IntlDateFormatter('ja_JP', IntlDateFormatter::FULL,
IntlDateFormatter::FULL, 'Asia/Tokyo', IntlDateFormatter::GREGORIAN);
echo 'It is now: "' . $formatter->format($now) . '" in Tokyo' . "\n";
//above gives [It is now: "2011年8月19日金曜日 23時32分27秒JST" in Tokyo]
$formatter = new IntlDateFormatter('ja_JP@calendar=japanese', IntlDateFormatter::FULL,
IntlDateFormatter::FULL, 'Asia/Tokyo', IntlDateFormatter::TRADITIONAL);
echo 'It is now: "' . $formatter->format($now) . '" in Tokyo' . "\n";
//above gives [It is now: "平成23年8月19日金曜日 23時32分27秒JST" in Tokyo]
?>
