PHP 时区列表

我正在寻找一种方法来生成要在 中显示的时区列表 使用 PHP 生成时区下拉列表

I am looking for a way to generate a list of timezones for display in a <select> Generating a drop down list of timezones with PHP

    $list = DateTimeZone::listAbbreviations();
    $idents = DateTimeZone::listIdentifiers();

    $data = $offset = $added = array();
    foreach ($list as $abbr => $info) {
        foreach ($info as $zone) {
            if ( ! empty($zone['timezone_id'])
                AND
                ! in_array($zone['timezone_id'], $added)
                AND 
                  in_array($zone['timezone_id'], $idents)) {
                $z = new DateTimeZone($zone['timezone_id']);
                $c = new DateTime(null, $z);
                $zone['time'] = $c->format('H:i a');
                $data[] = $zone;
                $offset[] = $z->getOffset($c);
                $added[] = $zone['timezone_id'];
            }
        }
    }

    array_multisort($offset, SORT_ASC, $data);
    $options = array();
    foreach ($data as $key => $row) {
        $options[$row['timezone_id']] = $row['time'] . ' - '
                                        . formatOffset($row['offset']) 
                                        . ' ' . $row['timezone_id'];
    }

    // now you can use $options;

function formatOffset($offset) {
        $hours = $offset / 3600;
        $remainder = $offset % 3600;
        $sign = $hours > 0 ? '+' : '-';
        $hour = (int) abs($hours);
        $minutes = (int) abs($remainder / 60);

        if ($hour == 0 AND $minutes == 0) {
            $sign = ' ';
        }
        return 'GMT' . $sign . str_pad($hour, 2, '0', STR_PAD_LEFT) 
                .':'. str_pad($minutes,2, '0');

}

当我检查我的国家时，偏移量是错误的，我在亚洲/新加坡，应该是UTC/GMT +8 http://www.timeanddate.com/worldclock/city.html?n=236 但根据生成的列表是 +9.是否存在某种逻辑错误?时间对了

When I checked my country, the offset was wrong, I am in Asia/Singapore, it should be UTC/GMT +8 http://www.timeanddate.com/worldclock/city.html?n=236 but according to the generated list its +9. Is there some kind of logic error? The time was correct tho

有没有更好的方法来生成这个列表?来自上面链接中的同一问题，

Is there a better way to generate this list? from the same question in the link above,

static $regions = array(
    'Africa' => DateTimeZone::AFRICA,
    'America' => DateTimeZone::AMERICA,
    'Antarctica' => DateTimeZone::ANTARCTICA,
    'Aisa' => DateTimeZone::ASIA,
    'Atlantic' => DateTimeZone::ATLANTIC,
    'Europe' => DateTimeZone::EUROPE,
    'Indian' => DateTimeZone::INDIAN,
    'Pacific' => DateTimeZone::PACIFIC
);
foreach ($regions as $name => $mask) {
    $tzlist[] = DateTimeZone::listIdentifiers($mask);
}

这只是获取我想要一个友好显示名称的标识符，例如.UTC+8 亚洲/新加坡或类似的地方.我怎样才能得到它?

This just gets the identifiers I want a friendly display name eg. UTC+8 Asia/Singapore or something similar. How can I get that?

推荐答案

以我专门为 select 元素制作的时区数组为例.它是关联数组，其中键是 PHP 时区，值是人类表示.就是这样:

Take my array of time zones, which I made specially for select element. It is associated array where key is PHP time zone and value is human representation. This is it:

$timezones = array(
    'Pacific/Midway'       => "(GMT-11:00) Midway Island",
