Generating a drop down list of timezones with PHP
提问by Xeoncross
Most sites need some way to show the dates on the site in the users preferred timezone. Below are two liststhat I found andthen one method using the built in PHP DateTimeclass in PHP 5.
大多数网站需要某种方式来在用户首选时区中显示网站上的日期。下面是我找到的两个列表，然后是一种使用PHP 5 中内置 PHP DateTime类的方法。
I need help knowing which of these would be the best to attempt to use when trying to get the UTC offset from the user on register.
我需要帮助知道在尝试从注册用户那里获取 UTC 偏移量时，哪些是最好的尝试使用。

Or just using PHP itself:
或者只是使用 PHP 本身：
$timezones = DateTimeZone::listAbbreviations();
$cities = array();
foreach( $timezones as $key => $zones )
{
foreach( $zones as $id => $zone )
{
/**
* Only get timezones explicitely not part of "Others".
* @see http://www.php.net/manual/en/timezones.others.php
*/
if ( preg_match( '/^(America|Antartica|Arctic|Asia|Atlantic|Europe|Indian|Pacific)\//', $zone['timezone_id'] )
&& $zone['timezone_id']) {
$cities[$zone['timezone_id']][] = $key;
}
}
}
// For each city, have a comma separated list of all possible timezones for that city.
foreach( $cities as $key => $value )
$cities[$key] = join( ', ', $value);
// Only keep one city (the first and also most important) for each set of possibilities.
$cities = array_unique( $cities );
// Sort by area/city name.
ksort( $cities );
It seems like the last one would be the safest as it would grow with the PHP release being used. You could also flip that array around when needed to tie timezones to city names.
似乎最后一个是最安全的，因为它会随着 PHP 版本的使用而增长。您还可以在需要将时区与城市名称联系起来时翻转该数组。

I would do it in PHP, except I would avoid doing preg_match 100 some times and do this to generate your list.
我会在 PHP 中执行此操作，但有时我会避免执行 preg_match 100 并执行此操作以生成您的列表。
$tzlist = DateTimeZone::listIdentifiers(DateTimeZone::ALL);
Also, I would use PHP's names for the 'timezones' and forget about GMT offsets, which will change based on DST. Code like that in phpbb is only that way b/c they are still supporting PHP4 and can't rely on the DateTime or DateTimeZone objects being there.
此外，我会使用 PHP 的名称作为“时区”，而忘记 GMT 偏移量，它会根据 DST 发生变化。phpbb 中的代码只是这样 b/c 他们仍然支持 PHP4 并且不能依赖存在的 DateTime 或 DateTimeZone 对象。

Following user210179's example above, I've written the following function to generate me a list of all timezones with their offsets:
按照上面 user210179 的示例，我编写了以下函数来生成所有时区及其偏移量的列表：
function generate_timezone_list()
{
static $regions = array(
DateTimeZone::AFRICA,
DateTimeZone::AMERICA,
DateTimeZone::ANTARCTICA,
DateTimeZone::ASIA,
DateTimeZone::ATLANTIC,
DateTimeZone::AUSTRALIA,
DateTimeZone::EUROPE,
DateTimeZone::INDIAN,
DateTimeZone::PACIFIC,
);
$timezones = array();
foreach( $regions as $region )
{
$timezones = array_merge( $timezones, DateTimeZone::listIdentifiers( $region ) );
}
$timezone_offsets = array();
foreach( $timezones as $timezone )
{
$tz = new DateTimeZone($timezone);
$timezone_offsets[$timezone] = $tz->getOffset(new DateTime);
}
// sort timezone by offset
asort($timezone_offsets);
$timezone_list = array();
foreach( $timezone_offsets as $timezone => $offset )
{
$offset_prefix = $offset < 0 ? '-' : '+';
$offset_formatted = gmdate( 'H:i', abs($offset) );
$pretty_offset = "UTC${offset_prefix}${offset_formatted}";
$timezone_list[$timezone] = "(${pretty_offset}) $timezone";
}
return $timezone_list;
}
This will generate an array looking like:
这将生成一个如下所示的数组：
[Pacific/Midway] => (UTC-11:00) Pacific/Midway
[Pacific/Pago_Pago] => (UTC-11:00) Pacific/Pago_Pago
[Pacific/Niue] => (UTC-11:00) Pacific/Niue
[Pacific/Honolulu] => (UTC-10:00) Pacific/Honolulu
[Pacific/Fakaofo] => (UTC-10:00) Pacific/Fakaofo
…
It's currently sorted by offsets, but you can easily sort by the timezone name by doing a ksort()instead of asort().
它目前按偏移量排序，但您可以通过执行ksort()而不是asort().
回答by Jonathan
Despite the number of existing answers, I've made yet another solution to this problem. The pro's of my implementation are:
尽管现有答案有很多，但我已经为这个问题提出了另一个解决方案。我的实现的优点是：
- The list of timezones is generated dynamically, and thus automatically updates when timezones might change (in PHP).
- Timezone names are prettified. For example, "America/St_Barthelemy" becomes "America, St. Barthelemy".
- Timezones are sorted on offset and name. Toland's answeronly sorts on offset, resulting in unsorted groups of timezones within the same offset.
- Offset information is not retrieved from
DateTimeZone::listAbbreviations, since that method also returns historical timezone information. Favio's answerdoes use this method, which results in incorrect (historical) offsets - The list of timezones is only generated when first requested (and 'cached' using a static variable).
- 时区列表是动态生成的，因此在时区可能发生变化时自动更新（在 PHP 中）。
- 时区名称经过美化。例如，“America/St_Barthelemy”变成“America, St. Barthelemy”。
- 时区按偏移量和名称排序。Toland 的答案仅按偏移量排序，导致同一偏移量内的时区组未排序。
- 不会从中检索偏移量信息
DateTimeZone::listAbbreviations，因为该方法还返回历史时区信息。Favio 的回答确实使用了这种方法，这会导致不正确的（历史）偏移 - 时区列表仅在首次请求时生成（并使用静态变量“缓存”）。
Here is the full code:
这是完整的代码：
function timezone_list() {
static $timezones = null;
if ($timezones === null) {
$timezones = [];
$offsets = [];
$now = new DateTime('now', new DateTimeZone('UTC'));
foreach (DateTimeZone::listIdentifiers() as $timezone) {
$now->setTimezone(new DateTimeZone($timezone));
$offsets[] = $offset = $now->getOffset();
$timezones[$timezone] = '(' . format_GMT_offset($offset) . ') ' . format_timezone_name($timezone);
}
array_multisort($offsets, $timezones);
}
return $timezones;
}
function format_GMT_offset($offset) {
$hours = intval($offset / 3600);
$minutes = abs(intval($offset % 3600 / 60));
return 'GMT' . ($offset ? sprintf('%+03d:%02d', $hours, $minutes) : '');
}
function format_timezone_name($name) {
$name = str_replace('/', ', ', $name);
$name = str_replace('_', ' ', $name);
$name = str_replace('St ', 'St. ', $name);
return $name;
}
And here's an example of the output
这是输出的示例
Array
(
[Pacific/Midway] => (GMT-11:00) Pacific, Midway
[Pacific/Niue] => (GMT-11:00) Pacific, Niue
[Pacific/Pago_Pago] => (GMT-11:00) Pacific, Pago Pago
[America/Adak] => (GMT-10:00) America, Adak
[Pacific/Honolulu] => (GMT-10:00) Pacific, Honolulu
[Pacific/Johnston] => (GMT-10:00) Pacific, Johnston
[Pacific/Rarotonga] => (GMT-10:00) Pacific, Rarotonga

I would do it with the following code which is similar to the accepted answer (I'm aware the code could be refactored :) ):
我会使用以下与接受的答案类似的代码来完成（我知道可以重构代码 :) ）：
$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');
$offset[] = $zone['offset'] = $z->getOffset($c);
$data[] = $zone;
$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');
}
It produces something like:
它产生类似的东西：
<option value="America/Boise" label="02:10 am - GMT-06:00 America/Boise">02:10 am - GMT-06:00 America/Boise</option>
<option value="America/Denver" label="02:10 am - GMT-06:00 America/Denver">02:10 am - GMT-06:00 America/Denver</option>
<option value="America/Edmonton" label="02:10 am - GMT-06:00 America/Edmonton">02:10 am - GMT-06:00 America/Edmonton</option>

You can create very easy a dropdown from this array (It was a time-consuming task to put this together and test it). We already use this list in some of our apps.
您可以非常容易地从这个数组创建一个下拉列表（将它们放在一起并进行测试是一项耗时的任务）。我们已经在我们的一些应用程序中使用了这个列表。
It is very importantto store timezone identifiers in your database and not just the timezone offset like "GMT+2", because of Daylight Saving Times.
这是非常重要的在你的数据库来存储时区标识符，而不仅仅是区偏移，因为夏令时报像“GMT + 2”。

也许无关紧要，但只要遵循最佳实践即可。见底部通知：http: //fr2.php.net/manual/en/timezones.others.php
Also, though this list has the Azores as GMT -1, in fact I think it's the same (at least sometimes) as GMT, but not sure.
此外，尽管此列表将亚速尔群岛设为 GMT -1，但实际上我认为它与 GMT 相同（至少有时），但不确定。

Here's one that creates a multidimensional array sorted by offset and niceified name:
这是创建一个按偏移量和精确名称排序的多维数组的方法：
function timezones() {
$timezones = [];
foreach (timezone_identifiers_list() as $timezone) {
$datetime = new \DateTime('now', new DateTimeZone($timezone));
$timezones[] = [
'sort' => str_replace(':', '', $datetime->format('P')),
'offset' => $datetime->format('P'),
'name' => str_replace('_', ' ', implode(', ', explode('/', $timezone))),
'timezone' => $timezone,
];
}
usort($timezones, function($a, $b) {
return $a['sort'] - $b['sort'] ?: strcmp($a['name'], $b['name']);
});
return $timezones;
}
foreach (timezones() as $timezone) {
echo '(UTC '.$timezone['offset'].') '.$timezone['name'].'<br>';
}
Echos:

$return[$timezone_identifier] = $text.' ('.$hours.':'.$mins.')';
}
return $return;
}
This PHP function give back an array of all existing Timezones including Offset:
这个 PHP 函数返回一个包含所有现有时区的数组，包括偏移量：
Use it e.g. like this:
像这样使用它：
print_r(time_zonelist());

I know this has an answer already but I saw an opportunity to improve upon one of the answers here. Toland H posted some very good code that does exactly what the question was asking for. Below is a shortened and expand version of Toland H's code:
我知道这已经有了答案，但我看到了改进这里答案之一的机会。Toland H 发布了一些非常好的代码，可以完全满足问题的要求。以下是 Toland H 代码的缩短和扩展版本：
- The function places everything in option tags for you. Just echo out whats return between your select tags.
- Major Improvement:The list is sorted first by continent and organized in option groups based on continents. Makes it very user friendly for visitors picking their timezone.
- 该函数为您将所有内容放在选项标签中。只需回显您选择的标签之间的返回内容即可。
- 主要改进：列表首先按大洲排序，并根据大洲按选项组进行组织。使访问者选择他们的时区变得非常用户友好。
function generate_timezone_list() {
static $allRegions = array(
DateTimeZone::AFRICA,
DateTimeZone::AMERICA,
DateTimeZone::ANTARCTICA,
DateTimeZone::ASIA,
DateTimeZone::ATLANTIC,
DateTimeZone::AUSTRALIA,
DateTimeZone::EUROPE,
DateTimeZone::INDIAN,
DateTimeZone::PACIFIC
);
// Makes it easier to create option groups next
$list = array ('AFRICA','AMERICA','ANTARCTICA','ASIA','ATLANTIC','AUSTRALIA','EUROPE','INDIAN','PACIFIC');
// Make array holding the regions (continents), they are arrays w/ all their cities
$region = array();
foreach ($allRegions as $area){
array_push ($region,DateTimeZone::listIdentifiers( $area ));
}
$count = count ($region); $i = 0; $holder = '';
// Go through each region one by one, sorting and formatting it's cities
while ($i < $count){
$chunck = $region[$i];
// Create the region (continents) option group
$holder .= '<optgroup label="---------- '.$list[$i].' ----------">';
$timezone_offsets = array();
foreach( $chunck as $timezone ){
$tz = new DateTimeZone($timezone);
$timezone_offsets[$timezone] = $tz->getOffset(new DateTime);
}
asort ($timezone_offsets);
$timezone_list = array();
foreach ($timezone_offsets as $timezone => $offset){
$offset_prefix = $offset < 0 ? '-' : '+';
$offset_formatted = gmdate( 'H:i', abs($offset) );
$pretty_offset = "UTC ${offset_prefix}${offset_formatted}";
$timezone_list[$timezone] = "(${pretty_offset}) $timezone";
}
// All the formatting is done, finish and move on to next region
foreach ($timezone_list as $key => $val){
$holder .= '<option value="'.$key.'">'.$val.'</option>';
}
$holder .= '</optgroup>';
++$i;
}
return $holder;
}
echo "<select>".generate_timezone_list()."</select>";
Then all you need to do is echo out what is returned between your html select tags. You'll get a select list something like this:
然后你需要做的就是回显你的 html select 标签之间返回的内容。你会得到一个像这样的选择列表：
----- AFRICA -----
(UTC +00:00) Africa/ city name
(UTC +01:00) Africa/ city name
(UTC +02:00) Africa/ city name
(UTC +02:00) Africa/ city name
----- AMERICA -----
(UTC -09:00) America/ city name
(UTC -07:00) America/ city name
(UTC +02:00) America/ city name
(UTC +05:00) America/ city name
And so on...
等等...
