i18nFormat() ¶ public

i18nFormat(array<int>|string|int|null $format = null, DateTimeZone|string|null $timezone = null, string|null $locale = null): string|int

Returns a formatted string for this time object using the preferred format and language for the specified locale.

It is possible to specify the desired format for the string to be displayed. You can either pass IntlDateFormatter constants as the first argument of this function, or pass a full ICU date formatting string as specified in the following resource: https://unicode-org.github.io/icu/userguide/format_parse/datetime/#datetime-format-syntax.

Additional to IntlDateFormatter constants and date formatting string you can use DateTime::UNIX_TIMESTAMP_FORMAT to get a unix timestamp

Examples

$time = new DateTime('2014-04-20 22:10');
$time->i18nFormat(); // outputs '4/20/14, 10:10 PM' for the en-US locale
$time->i18nFormat(\IntlDateFormatter::FULL); // Use the full date and time format
$time->i18nFormat([\IntlDateFormatter::FULL, \IntlDateFormatter::SHORT]); // Use full date but short time format
$time->i18nFormat('yyyy-MM-dd HH:mm:ss'); // outputs '2014-04-20 22:10'
$time->i18nFormat(DateTime::UNIX_TIMESTAMP_FORMAT); // outputs '1398031800'

You can control the default format used through DateTime::setToStringFormat().

You can read about the available IntlDateFormatter constants at https://secure.php.net/manual/en/class.intldateformatter.php

If you need to display the date in a different timezone than the one being used for this Time object without altering its internal state, you can pass a timezone string or object as the second parameter.

Finally, should you need to use a different locale for displaying this time object, pass a locale string as the third parameter to this function.

Examples

$time = new Time('2014-04-20 22:10');
$time->i18nFormat(null, null, 'de-DE');
$time->i18nFormat(\IntlDateFormatter::FULL, 'Europe/Berlin', 'de-DE');

You can control the default locale used through DateTime::setDefaultLocale(). If empty, the default will be taken from the intl.default_locale ini config.

Parameters

array<int>|string|int|null $format optional: Format string.
DateTimeZone|string|null $timezone optional: Timezone string or DateTimeZone object in which the date will be displayed. The timezone stored for this object will not be changed.
