i18nFormat() ¶ public

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

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: http://www.icu-project.org/apiref/icu4c/classSimpleDateFormat.html#details.

Examples

$time = new Time('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'

If you wish to control the default format to be used for this method, you can alter the value of the static Time::$defaultLocale variable and set it to one of the possible formats accepted by this function.

You can read about the available IntlDateFormatter constants at http://www.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 to be used by setting the static variable Time::$defaultLocale to a valid locale string. If empty, the default will be taken from the intl.default_locale ini config.

Parameters

string|int|null $format optional: Format string.
string|DateTimeZone|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.
