限時送ChatGPT賬號..
我正在尋找一種方法來生成要在 中顯示的時區列表 使用 PHP 生成時區下拉列表
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');
}
當我檢查我的國家時，偏移量是錯誤的，我在亞洲/新加坡，應該是UTC/GMT +8 http://www.timeanddate.com/worldclock/city.html?n=236 但根據生成的列表是 +9.是否存在某種邏輯錯誤?時間對了
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
有沒有更好的方法來生成這個列表?來自上面鏈接中的同一問題，
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);
}
這只是獲取我想要一個友好顯示名稱的標識符，例如.UTC+8 亞洲/新加坡或類似的地方.我怎樣才能得到它?
This just gets the identifiers I want a friendly display name eg. UTC+8 Asia/Singapore or something similar. How can I get that?
