DateTimeZone::listIdentifiers

(PHP 5 >= 5.2.0)

DateTimeZone::listIdentifiers — Returns numerically index array with all timezone identifiers

面向对象风格

public static array DateTimeZone::listIdentifiers ([ int $what = DateTimeZone::ALL [, string $country = NULL ]] )

过程化风格

array timezone_identifiers_list ([ int $what = DateTimeZone::ALL [, string $country = NULL ]] )

what: One of DateTimeZone class constants.
country: A two-letter ISO 3166-1 compatible country code.

Note: This option is only used when what is set to DateTimeZone::PER_COUNTRY.

Returns array on success 或者在失败时返回 FALSE.

版本	说明
5.3.0	Added the optional `what` and `country` parameters.


<?php
$timezone_identifiers = DateTimeZone::listIdentifiers();
for ($i=0; $i < 5; $i++) {
    echo "$timezone_identifiers[$i]\n";
}
?>

以上例程的输出类似于：

Africa/Abidjan
Africa/Accra
Africa/Addis_Ababa
Africa/Algiers
Africa/Asmara
