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
