$object
[, mixed $format = NULL
[, string $locale = NULL
]] )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.
Список параметров
-
object -
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), a long 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
NULLto use the default one.
Возвращаемые значения
A string with result или FALSE в случае возникновения ошибки.

`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 slowerIf 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 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!
