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.
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.
A string with result 或者在失败时返回 false.
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
