): string|falseThis 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. Ifnull
, 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
.
范例
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";
以上例程会输出:
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 slower! `format` is more then 10-13 times faster! (on PHP 5.5) Use the `format` method instead of the static `formatObject`.

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