Create a date formatter.

参数

locale

Locale to use when formatting or parsing or null to use the value specified in the ini setting intl.default_locale.

dateType

Format of the date determined by one of the IntlDateFormatter constants. The default value is IntlDateFormatter::FULL.

timeType

Format of the time determined by one of the IntlDateFormatter constants. The default value is IntlDateFormatter::FULL.

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 ICUʼs 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 » https://unicode-org.github.io/icu/userguide/format_parse/datetime/.

返回值

The created IntlDateFormatter or null in case of failure.

示例

示例 #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);
?>

示例 #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);
?>

示例 #3 Example of invalid locale handling

<?php
try {
$fmt = new IntlDateFormatter(
'invalid_locale',
IntlDateFormatter::FULL,
IntlDateFormatter::FULL,
'dunno',
IntlDateFormatter::GREGORIAN,
);
} catch (\Error $e) {
// ...
}
?>

以上示例会输出：

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
