说明

面向对象风格

public static IntlDateFormatter::formatObject(IntlCalendar|DateTimeInterface $datetime, array|int|string|null $format = null, ?string $locale = null): string|false

过程化风格

datefmt_format_object(IntlCalendar|DateTimeInterface $datetime, array|int|string|null $format = null, ?string $locale = null): string|false

This function allows formatting an IntlCalendar or DateTime object without first explicitly creating a IntlDateFormatter object.

The temporary IntlDateFormatter that will be created will take the timezone from the passed in object. The timezone database bundled with PHP will not be used – ICU's will be used instead. The timezone identifier used in DateTime objects must therefore also exist in ICU's database.

参数

datetime

An object of type IntlCalendar or DateTime. The timezone information in the object will be used.

format

How to format the date/time. This can either be an array with two elements (first the date style, then the time style, these being one of the constants IntlDateFormatter::NONE, IntlDateFormatter::SHORT, IntlDateFormatter::MEDIUM, IntlDateFormatter::LONG, IntlDateFormatter::FULL), an int with the value of one of these constants (in which case it will be used both for the time and the date) or a string with the format described in » the ICU documentation. If null, the default style will be used.

locale

The locale to use, or null to use the default one.

返回值

A string with result 或者在失败时返回 false.

示例

示例 #1 IntlDateFormatter::formatObject() examples

<?php
/* default timezone is irrelevant; timezone taken from the object */
ini_set('date.timezone', 'UTC');
/* default locale is taken from this ini setting */
ini_set('intl.default_locale', 'fr_FR');

$cal = IntlCalendar::fromDateTime("2013-06-06 17:05:06 Europe/Dublin");
echo
"default:\n\t",
IntlDateFormatter::formatObject($cal),
"\n";

echo
"long \$format (full):\n\t",
IntlDateFormatter::formatObject($cal, IntlDateFormatter::FULL),
"\n";

echo
"array \$format (none, full):\n\t",
IntlDateFormatter::formatObject($cal, array(
IntlDateFormatter::NONE,
IntlDateFormatter::FULL)),
"\n";

echo
"string \$format (d 'of' MMMM y):\n\t",
IntlDateFormatter::formatObject($cal, "d 'of' MMMM y", 'en_US'),
"\n";

echo
"with DateTime:\n\t",
IntlDateFormatter::formatObject(
new
DateTime("2013-09-09 09:09:09 Europe/Madrid"),
IntlDateFormatter::FULL,
'es_ES'),
"\n";

以上示例会输出:

default:
    6 juin 2013 17:05:06
long $format (full):
    jeudi 6 juin 2013 17:05:06 heure d’été irlandaise
array $format (none, full):
    17:05:06 heure d’été irlandaise
string $format (d 'of' MMMM y):
    6 of June 2013
with DateTime:
    lunes, 9 de septiembre de 2013 09:09:09 Hora de verano de Europa central

`format` vs static `formatObject`

** The `formatObject` is NOT slower! (on PHP 5.5) **

Use either the `format` method or the static `formatObject`.

Since `formatObject` is doing the work of `new IntlDateFormatter` with the provided pattern, the instantiation line must be included in the loop!

Another debunked flawed false test!

If you want to format a date according to a specific scheme and in a local language, here is the link to the reference of the formatting codes to use, I did not find it directly in the documentation:
https://unicode-org.github.io/icu/userguide/format_parse/datetime/#date-field-symbol-table
Here is a test using a DateTime object :

<?php

// must be required by the server
date_default_timezone_set( 'Europe/Paris' );

// instantiate a new DateTime object
$dateTimeObj = new DateTime('now', new DateTimeZone('Europe/Paris'));

// format the date with a specific scheme
// the 3 parameters are [ DateTimeObject, ICU Scheme, locale code string ]
$dateFromatted = IntlDateFormatter::formatObject( $dateTimeObj, "eee d MMMM y à HH:mm", 'fr' );

// test :
echo ucwords($dateFromatted);
// output : Jeu. 7 Avril 2022 à 04:36 // formatted as i want

`format` vs static `formatObject`

The `formatObject` is slower! `format` is more then 10-13 times faster! (on PHP 5.5) Use the `format` method instead of the static `formatObject`.

It's still slower on php7.1, but not that dramatic anymore, here I got something around 5times slower
