Мне нужно отобразить селектор часового пояса в качестве пользовательского элемента управления, который всегда кажется более простым, чем есть на самом деле. Внутри я храню все с помощью идентификатора DateTimeZone, поскольку это, по-видимому, самый умный способ получить нужный уровень точности, поскольку этот проект наводит мосты в реальном времени, поскольку он привязан к наземным средам.
То, что я не хочу делать, представляет собой поле выбора с более чем 300 часовыми поясами, и я не хочу создавать фальшивые смещения часового пояса с чем-то вроде UTC-8 (который теряет не только информацию DST, но и фактические даты, которые DST падает).
В конце концов, мне понадобится выбор с параметрами, содержащими правильные идентификаторы TZD, что-то вроде этого (заключенные в квадратные скобки #s не нужны, только для потенциальной иллюстрации конечного пользователя):
<select> <option value="America/Los_Angeles">Los Angeles [UTC-7 | DST]</option> ... </select> У кого-нибудь есть указатели на создание этого списка? Все решения, которые я искал, были так или иначе проблематичными.
Я добавил щедрость на случай, если кто-то соберет кого-нибудь, чтобы поделиться с нами более приятным ответом. 🙂
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 $sign . str_pad($hour, 2, '0', STR_PAD_LEFT) .':'. str_pad($minutes,2, '0'); } $utc = new DateTimeZone('UTC'); $dt = new DateTime('now', $utc); echo '<select name="userTimeZone">'; foreach(DateTimeZone::listIdentifiers() as $tz) { $current_tz = new DateTimeZone($tz); $offset = $current_tz->getOffset($dt); $transition = $current_tz->getTransitions($dt->getTimestamp(), $dt->getTimestamp()); $abbr = $transition[0]['abbr']; echo '<option value="' .$tz. '">' .$tz. ' [' .$abbr. ' '. formatOffset($offset). ']</option>'; } echo '</select>';
Вышеизложенное выведет все часовые пояса в меню выбора в следующем формате:
<select name="userTimeZone"> <option value="America/Los_Angeles">America/Los_Angeles [PDT -7]</option> </select>
Мое решение:
Чтобы избежать огромного списка часовых поясов, сначала выберите страну, затем используйте эту информацию, чтобы заполнить список часовых поясов.

Надеюсь, это поможет вам 🙂
Если вы хотите делать что-то с zoneinfo, у вас действительно нет выбора, кроме как включать сотни записей, потому что это именно так, как работает зонаинфо. Как правило, по крайней мере одна запись для каждой страны, и есть около 200 стран (согласно Википедии ).
То, что я делал ранее, – использовать timezone_identifiers_list() и отфильтровать любую запись, которая не находится в одном из стандартных регионов:
# Output option list, HTML. $opt = ''; $regions = array('Africa', 'America', 'Antarctica', 'Arctic', 'Asia', 'Atlantic', 'Australia', 'Europe', 'Indian', 'Pacific'); $tzs = timezone_identifiers_list(); $optgroup = ''; sort($tzs); foreach ($tzs as $tz) { $z = explode('/', $tz, 2); # timezone_identifiers_list() returns a number of # backwards-compatibility entries. This filters them out of the # list presented to the user. if (count($z) != 2 || !in_array($z[0], $regions)) continue; if ($optgroup != $z[0]) { if ($optgroup !== '') $opt .= '</optgroup>'; $optgroup = $z[0]; $opt .= '<optgroup label="' . htmlentities($z[0]) . '">'; } $opt .= '<option value="' . htmlentities($tz) . '" label="' . htmlentities(str_replace('_', ' ', $z[1])) . '">' . htmlentities(str_replace('_', ' ', $tz)) . '</option>'; } if ($optgroup !== '') $opt .= '</optgroup>';
Это создает список с элементами <optgroup> , поэтому список будет по крайней мере логически разделен по региону.
Я нашел, что это отличный ресурс: http://randomdrake.com/2008/08/06/time-zone-abbreviation-difficulties-with-php/
В конце концов, я не думаю, что есть хорошее решение для предварительной отбраковки слишком большого списка часовых поясов … И связанные с этим проблемы заставили меня решить начать с класса приличного размера. Я размещаю его здесь, так как есть люди, которые его интересовали. Надеюсь, мое решение поможет кому-то еще.
Что оно делает:
Позволяет создать список часовых поясов из всего списка внутри PHP
Позволяет создать хороший список из ваших собственных предварительно искушенных определений, вычисляя текущие смещения UTC.
Позволяет создать список по странам.
Уничтожает временные интервалы с той же аббревиатурой. Обратите внимание, что я не провел много исследований, чтобы увидеть, есть ли дубликаты в списке, от которых я не должен избавляться. Это достаточно разумно, чтобы знать, что хотя два часовых пояса могут сообщать о том же аббревиатуре (например, MST для Аризоны), что он будет дополнительно определять, поддерживает ли часовой пояс DST в любое время года.
Выводит либо достаточно настраиваемый HTML (без перехода в шаблонный маршрут), либо JSON для Ajax или встроенного JavaScript.
Вычисляет текущее смещение часового пояса для любого заданного часового пояса. Обратите внимание, что это не статично … он будет меняться круглый год.
Обеспечивает большое количество сахара для использования в реальном мире.
Что это не делает:
Вещи, которые я мог бы добавить в один день:
Создайте HTML из шаблона вместо встроенного, как это.
Дополнительные селекторы, например, взятие нескольких стран вместо одного.
Группировка, но, как я уже упоминал выше, я делаю это.
Код довольно влажный. Есть некоторые незначительные несоответствия в стиле кодирования.
Возможность указать «предпочтительный» список дружественных имен. Например, хотя «Доусон» является вполне жизнеспособным кандидатом, который будет указан как «город для ФДТ», поскольку он является частью основной группы PST и наблюдает за летним временем … город, насчитывающий более 1000 жителей, не должен избили Лос-Анджелес, Сан-Франциско, Сиэтл или Ванкувер только потому, что он появляется сначала лексически.
Сырой выход, так что никто не привязан к простым методам «toSelect» и «toJson».
В общем, он должен соответствовать моим потребностям, как есть. Он правильно обрабатывает все временные зоны, с которыми я знаком, и все те, которые мне нужны для моего текущего проекта. К сожалению, мой объем знаний сосредоточен в основном вокруг США и Западной Европы.
Это прекрасно? Возможно нет. С удовольствием узнаем о любых проблемах / ошибках / улучшениях, которые могут иметь люди с этим кодом, поскольку это, скорее всего, закончится в моей постоянной библиотеке. Если кто-то думает, что я высок … дайте мне знать об этом. В этом весь смысл этого вопроса заключался в том, чтобы найти лучший способ точно представлять селектор часового пояса, что на самом деле полезно для конечных пользователей.

Уф. Вот примеры использования (timezones.php):
<?php include_once 'TimezoneList.php'; /* Example 1: Get Select Box by Country Code */ $tzl = TimezoneList::byCountry('US'); $tzl = $tzl->getUniqueTimezoneList(); echo $tzl->toSelect(true,true,'America/Los_Angeles'); echo "\n".'<br />'."\n"; /* Example 2: Get a list by country code, output as JSON for AJAX (or similar uses) */ $_REQUEST['country_code'] = 'US'; // Hack for quick usage. $tzl_ajax = TimezoneList::byCountry($_REQUEST['country_code']); $tzl_ajax = $tzl_ajax->getUniqueTimezoneList(); echo '<script type="text/javascript">'."\n"; echo 'var foo = '.$tzl_ajax->toJson().';'; echo "\n".'</script>'; echo "\n".'<br />'."\n"; /* Example 3: Get Select Box from a list of TZDs + friendly names */ $tzl2 = TimezoneList::fromIdentifierList( array('America/Los_Angeles','America/Boise','America/Phoenix','America/Chicago','America/New_York'), array('Pacific','Mountain','Mountain (Arizona)','Central','Eastern') ); // Example shows setting extra properties on the <SELECT>. echo $tzl2->toSelect(true,false,'America/Los_Angeles', array('style'=>'font-size:15px; border:1px solid #ccc; padding:4px', 'id'=>'timezone_list', 'class'=>'standard-list', 'name'=>'timezone') ); echo "\n".'<br />'."\n"; /* Example 4: Get a raw list of timezones */ $tzl3 = new TimezoneList(true); $tzl3 = $tzl3->getUniqueTimezoneList(); echo $tzl3->toSelect(true,false,'America/Los_Angeles');

Я придумал динамическое самообновляемое решение, которое не требует каких-либо поисковых таблиц ( выберите демо ):
function Timezones() { $result = array(); $timezones = array(); // only process geographical timezones foreach (preg_grep('~^(?:A(?:frica|merica|ntarctica|rctic|tlantic|sia|ustralia)|Europe|Indian|Pacific)/~', timezone_identifiers_list()) as $timezone) { if (is_object($timezone = new DateTimeZone($timezone)) === true) { $id = array(); // get only the two most distant transitions foreach (array_slice($timezone->getTransitions($_SERVER['REQUEST_TIME']), -2) as $transition) { // dark magic $id[] = sprintf('%b|%+d|%u', $transition['isdst'], $transition['offset'], $transition['ts']); } if (count($id) > 1) { sort($id, SORT_NUMERIC); // sort by %b (isdst = 0) first, so that we always get the raw offset } $timezones[implode('|', $id)][] = $timezone->getName(); } } if ((is_array($timezones) === true) && (count($timezones) > 0)) { uksort($timezones, function($a, $b) // sort offsets by -, 0, + { foreach (array('a', 'b') as $key) { $$key = explode('|', $$key); } return intval($a[1]) - intval($b[1]); }); foreach ($timezones as $key => $value) { $zone = reset($value); // first timezone ID is our internal timezone $result[$zone] = preg_replace(array('~^.*/([^/]+)$~', '~_~'), array('$1', ' '), $value); // "humanize" city names if (array_key_exists(1, $offset = explode('|', $key)) === true) // "humanize" the offset { $offset = str_replace(' +00:00', '', sprintf('(UTC %+03d:%02u)', $offset[1] / 3600, abs($offset[1]) % 3600 / 60)); } if (asort($result[$zone]) === true) // sort city names { $result[$zone] = trim(sprintf('%s %s', $offset, implode(', ', $result[$zone]))); } } } return $result; }
Есть много часовых поясов, которые используют одни и те же смещения и тайм-ауты DST ( Europe/Dublin , Europe/Lisbon и Europe/London чтобы назвать несколько), мой алгоритм группирует эти зоны (используя специальную нотацию в массиве dst?|offset|timestamp ) в первом идентификаторе временной зоны этой группы и объединяет гуманизированные преобразования последнего сегмента (обычно городского уровня) временного интервала ID:

Granted, the city concatenation is still pretty damn long but the list of unique (actual) timezones has dropped from 414 (or 415, if we consider the non-geographical UTC) to 75 – which is pretty good IMO and seems to reflect the list of "normalized" timezones Windows uses (also 75).
There are two big problems with this automated approach:
Atlantic/Canary – while there shouldn't be anything wrong with that, it would make more sense to pick a timezone ID associated with a bigger city (like Europe/London ) array_slice($cities, 0, $maxCities) before imploding but this wouldn't have the city dimension into account, and for a limit of 4 Canary, Dublin, Faroe, Guernsey, Isle of Man, Jersey, Lisbon, London, Madeira would become Canary, Dublin, Faroe, Guernsey instead of the more logical Windows equivalent Dublin, Edinburgh, Lisbon, London . This shouldn't be very useful as it it, but I thought I'd share – perhaps someone else can improve it.
I can think of a few options.
First being to populate the whole select list, and use a jQuery plugin like Chosen to populate the entire list. This would probably suck since your users might not even know all of the timezones.
Second option being to use JS to get the browser's local time in a hidden input field, and combine that with knowledge of the users IP to try to deduce the users location transparently. You could even display their assumed location on a map and ask them if you have the correct time.
Third option is to actually ask the user where they live. Country and postal code should probably be enough to get the timezone for most users. In edge cases you could ask the user to clarify.
Personally, I'd probably combine the first and second solution to make a select list display the regions you believe the user is closest to.
Perhaps we could use a pregenerated list like the one presented here: http://www.ultramegatech.com/blog/2009/04/working-with-time-zones-in-php
After thinking (and testing) a lot about this problem I've come to the conclusion that you can't use timezone short-lists for the simple fact that timezone rules are dynamic (more than you might expect – 4 timezones will have their rules changed this month) and groups/concatenations/abbreviations are static.
Here is the code for the approach I decided to stick with:
function Timezones($country = null, $continent = null) { $result = array(); if (is_array($timezones = DateTimeZone::listIdentifiers()) === true) { $timestamp = strtotime('-6 months', time()); if ((strlen($country) == 2) && (defined('DateTimeZone::PER_COUNTRY') === true)) { $timezones = DateTimeZone::listIdentifiers(DateTimeZone::PER_COUNTRY, $country); } foreach (preg_grep('~' . preg_quote($continent, '~') . '/~i', $timezones) as $id) { $timezone = new DateTimeZone($id); if (is_array($transitions = $timezone->getTransitions()) === true) { while ((isset($result[$id]) !== true) && (is_null($transition = array_shift($transitions)) !== true)) { $result[$id] = (($transition['isdst'] !== true) && ($transition['ts'] >= $timestamp)) ? $transition['offset'] : null; } } } if (array_multisort($result, SORT_NUMERIC, preg_replace('~^[^/]+/~', '', array_keys($result)), SORT_REGULAR, $result) === true) { foreach ($result as $key => $value) { $result[$key] = sprintf('(GMT %+03d:%02u) %s', $value / 3600, abs($value) % 3600 / 60, ltrim(strstr($key, '/'), '/')); } } } return str_replace(array(' +00:00', '_', '/'), array('', ' ', ' - '), $result); }
Demo at http://www.ideone.com/VYWtw and http://jsfiddle.net/hSxa8/embedded/result/ .
There is a list/reference provided in the answer to this question . It comes up with just 88 unique timezones that would make up your select list.
This has long been answered but, I wasn't satisfied with any of the answers that forced users to go through all the TZ entries php knows. Instead I created a more concise list that maps times like eastern time to America/New_York and includes special entries for odd locations like Arizona.
