Большинству сайтов нужен способ отображать даты на сайте в часовом поясе, предпочитаемом пользователями. Ниже приведены два списка, которые я нашел, а затем один метод, использующий встроенный класс PHP DateTime в PHP 5.
Мне нужна помощь, чтобы узнать, какой из них лучше всего попытаться использовать при попытке получить смещение UTC от зарегистрированного пользователя.
Один:

Или просто используя сам PHP:
$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 );
Похоже, что последний вариант будет самым безопасным, так как он будет расти с использованием версии PHP. Вы также можете перевернуть этот массив, когда необходимо привязать часовые пояса к названиям городов.
Ответы:
Я бы сделал это на PHP, но я бы не стал делать preg_match 100 несколько раз и сделал бы это для создания вашего списка.
Кроме того, я бы использовал имена PHP для «часовых поясов» и забыл о смещениях по Гринвичу, которые будут меняться в зависимости от летнего времени. Такой код в phpbb - это только такой способ, b / c они все еще поддерживают PHP4 и не могут полагаться на присутствующие там объекты DateTime или DateTimeZone.

Undefined class constant 'AFRICA'когда пытаюсь использовать класс DateTimeZone. Я проверил определенные классы, и они перечислены, так что, возможно, Windows нужно что-то еще, чтобы это работало.$regionsзначение1023заменит все эти константы. Кроме того, если вам нужны регулярные выражения, рассмотритеpreg_grep()вместоpreg_match().DateTimeZone::ALLвместо создания массива доступных регионов и перебора его.Следуя приведенному выше примеру пользователя210179, я написал следующую функцию для создания списка всех часовых поясов с их смещениями:
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; }Это сгенерирует массив вида:
[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 …В настоящее время он отсортирован по смещению, но вы можете легко отсортировать его по имени часового пояса, выполнив
ksort()вместоasort().источник
$timezones = DateTimeZone::listIdentifiers( DateTimeZone::ALL );Если вы хотите включить только определенные регионы, вы можете позвонить$timezones = DateTimeZone::listIdentifiers( DateTimeZone::AMERICA | DateTimeZone::EUROPE );UTC-11.00,UTC-10.00, ... ,UTC-01.00,UTC+14.00,UTC-13.00, ... ,UTC+00.00, чтобы отсортировать их какUTC-11.00,UTC-10.00, ... ,UTC-01.00,UTC+00.00,UTC+01.00, ... ,UTC+13.00,UTC-14.00array_mergeне следует использовать в цикле.Несмотря на количество существующих ответов, я нашел еще одно решение этой проблемы. Плюсы моей реализации:
DateTimeZone::listAbbreviations, поскольку этот метод также возвращает историческую информацию о часовом поясе . Ответ Favio действительно использует этот метод, что приводит к неправильным (историческим) смещениямВот полный код:
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 $name; }А вот пример вывода
Array ( [Pacific/Midway] => (GMT-11:00) Pacific, Midway [Pacific/Niue] => (GMT-11:00) Pacific, Niue [Pacific/Pago_Pago] => (GMT-11:00) Pacific, Pago Pago [America/Adak] => (GMT-10:00) America, Adak [Pacific/Honolulu] => (GMT-10:00) Pacific, Honolulu [Pacific/Johnston] => (GMT-10:00) Pacific, Johnston [Pacific/Rarotonga] => (GMT-10:00) Pacific, Rarotonga [Pacific/Tahiti] => (GMT-10:00) Pacific, Tahiti [Pacific/Marquesas] => (GMT-09:30) Pacific, Marquesas [America/Anchorage] => (GMT-09:00) America, Anchorage ... )источник
line 73. Я знаю, что этого не может быть слишком сложно, но я просто не могу понять, в чем я терплю неудачу. Любые мысли были бы очень признательны!$timezones = [];на$timezones = array();и$offsets = [];на$offsets = array();.Я бы сделал это с помощью следующего кода, который похож на принятый ответ (я знаю, что код можно отредактировать :)):
$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'); }Это производит что-то вроде:
<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> <option value="America/Inuvik" label="02:10 am - GMT-06:00 America/Inuvik">02:10 am - GMT-06:00 America/Inuvik</option> <option value="America/Shiprock" label="02:10 am - GMT-06:00 America/Shiprock">02:10 am - GMT-06:00 America/Shiprock</option> <option value="America/Belize" label="02:10 am - GMT-05:00 America/Belize">02:10 am - GMT-05:00 America/Belize</option>Надеюсь, что это немного поможет и / или вдохновит вас на что-то лучшее.

$zone['offset'] = $z->getOffset($c);до$data[] = $zone;исправляет отображаемые смещения.DateTimeZone::listAbbreviations, чтобы получить правильный список часовых поясов.Вы можете очень легко создать раскрывающийся список из этого массива (собрать его и протестировать было трудоемкой задачей). Мы уже используем этот список в некоторых наших приложениях.
Это очень важно для идентификаторов магазина часовых поясов в базе данных , а не только смещение часового пояса , как «GMT + 2», из - за Летнюю Times.

Редактирование ответа Тамаса для удаления всех «других» записей, которые, по словам сайта php.net, больше не должны использоваться.
Может быть, это не имеет значения, но просто следуйте лучшим практикам. См. Уведомление внизу: http://fr2.php.net/manual/en/timezones.others.php
Кроме того, хотя в этом списке Азорские острова указаны как GMT -1, на самом деле я думаю, что это то же самое (по крайней мере, иногда), что и GMT, но не уверен.
Редактирование, чтобы предложить это в sql, чтобы вы могли создать раскрывающийся список в форме и вместо этого привязать ответ пользователя к индексу.
Снова редактируем, чтобы удалить начальный пробел

Использование listAbbreviations () не имеет смысла, поскольку для каждой области он возвращает все различные смещения, которые использовались там исторически, а не только текущие. Правильный базовый источник списка определенно listIdentifiers ().
Я бы сгенерировал список только один раз и сохранил его, чтобы не создавать его для каждого запроса. Я мог обновлять его раз в месяц.
Кроме того, я мог бы поместить всю информацию о часовых поясах в отдельный js-скрипт и создать сам список выбора на стороне клиента. Js-скрипт тоже можно кешировать, часовые пояса меняются нечасто.
Кроме того, используя javascript на стороне клиента, вы можете узнать текущее местное время и, следовательно, вы можете найти зоны с одинаковым временем (минуты могут отличаться, поэтому сравнение должно быть приблизительным) и отобразить их в верхней части list, поэтому пользователю не нужно прокручивать все 400 элементов. Вы также можете отобразить соседние зоны (+/- 1 час) после.

Я знаю, что на это уже есть ответ, но я увидел возможность улучшить один из ответов здесь. Толанд Х опубликовал очень хороший код, который делает именно то, о чем спрашивал вопрос. Ниже представлена сокращенная и расширенная версия кода Toland H:
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>";Затем все, что вам нужно сделать, это повторить то, что возвращается между вашими тегами выбора html. Вы получите список выбора примерно так:
----- 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 nameИ так далее...

Эта функция PHP выполняет задание за вас и возвращает массив:

В некоторых проектах действительно не имеет смысла указывать подробные часовые пояса Африки, Европы или Тихого океана. Итак, вот краткая версия

public static function tzList() { $tzMap = array(); $zones = \DateTimeZone::listIdentifiers(); foreach ($zones as $zone) { $tz = new \DateTimeZone($zone); $now = new \DateTime("utc", $tz); $diffInSeconds = $tz->getOffset($now); $hours = floor($diffInSeconds / 3600); $minutes = floor(($diffInSeconds % 3600) / 60); $tzMap[$zone] = sprintf("%+d", $hours) . ":" . sprintf("%02d", $minutes); } return $tzMap; }Тада! Все очень просто. Предоставляет вам массив с ключом в качестве часового пояса PHP и значением в виде строки в формате + -Hours: Minutes

Я создал для этого класс PHP с соответствующим плагином jQuery. Я открыл его на https://github.com/peterjtracey/timezoneWidget - код PHP вдохновлен другим ответом stackoverflow, но я думаю, что он намного элегантнее. Плагин jQuery предоставляет отличный интерфейс для выбора часового пояса.

первый вариант позволит вам взять значение из $ _POST ['whateveryoucalltheselect'] и добавить его в UTC. или даже сохраните это значение, а затем всегда вызывайте UTC + userTZsetting, когда вам это понадобится позже. мне кажется самым простым. последний вариант был бы гораздо более ценным, если бы часовые пояса менялись часто.
источник
Никто из них. Вместо этого подготовьте массив в PHP с этими часовыми поясами. подобно
$arr[0] = "(GMT+02:00) Harare, Pretoria"; $arr[1] = "(GMT+03:00) Jerusalem";или
$arr[0] = array("America/Campo_Grande", "(GMT+02:00) Harare, Pretoria"); $arr[1] = array("America/Israel", "(GMT+03:00) Jerusalem");и так далее. Затем сгенерируйте форму на основе этого массива:
foreach ($arr as $k => $v) $str .= "<option value=$k>$v[1]</option>";И тогда вы можете легко переключаться на разные форматы, просто изменив код в строке выше. Также проверка будет намного проще и не потребует регулярных выражений. Просто сравните значение, отправленное POST или GET, с массивом. Теперь легко установить, что $ arr [$ value_sent_by_form] [0] содержит PHP-совместимое значение, а $ arr [$ value_sent_by_form] [1] удобное для пользователя значение.

См. Также этот пример
<?php function get_timezones() { $o = array(); $t_zones = timezone_identifiers_list(); foreach($t_zones as $a) { $t = ''; try { //this throws exception for 'US/Pacific-New' $zone = new DateTimeZone($a); $seconds = $zone->getOffset( new DateTime("now" , $zone) ); $hours = sprintf( "%+02d" , intval($seconds/3600)); $minutes = sprintf( "%02d" , ($seconds%3600)/60 ); $t = $a ." [ $hours:$minutes ]" ; $o[$a] = $t; } //exceptions must be catched, else a blank page catch(Exception $e) { //die("Exception : " . $e->getMessage() . '<br />'); //what to do in catch ? , nothing just relax } } ksort($o); return $o; } $o = get_timezones(); ?> <html> <body> <select name="time_zone"> <?php foreach($o as $tz => $label) { echo "<option value="$tz">$label</option>"; } ?> </select> </body> </html>источник
Перепробовав все представленные здесь решения и не получив удовлетворения, я нашел сценарий, который соответствует моим потребностям и более удобен для пользователя. Для протокола сохраню как возможное решение. Мне нравятся решения для копирования / вставки :)
Скрипт возвращает выбор с любым часовым поясом, который вы хотите предварительно выбрать.

Timezone:all(), и это дает вам массив в форматеUTC-5:00 (America, New York), чтобы вы могли легко отобразить поле выбора в своем интерфейсе.источник
Для тех, кто использует CodeIgniter, есть встроенная функция Date Helper, называемая timezone_menu . Эти:
$this->load->helper('date'); echo timezone_menu('GMT', 'form-control', 'dropdown-name', ['id' => 'ci-timezone']);Произведите следующий вывод:

Я сделал это:
php -r "echo json_encode(array_combine(DateTimeZone::listIdentifiers(DateTimeZone::ALL), DateTimeZone::listIdentifiers(DateTimeZone::ALL)));" > list-of-timezones.jsonисточник
Я бы хотел оставить здесь эту идею:
/*----------TIME ZONE LIST---------*/ function TZList($data_type = false){ $_all_timezone_identifiers = DateTimeZone::listIdentifiers(DateTimeZone::ALL); $TIMEZONE_LIST = array(); foreach($_all_timezone_identifiers as $k => $v){ $_tzone_group = explode("/", $_all_timezone_identifiers[$k])[0]; $_tzone_new = new DateTimeZone($_all_timezone_identifiers[$k]); $_tzone_new_date = new DateTime("now", $_tzone_new); $tzone_arr = array( 'timezone' => $_all_timezone_identifiers[$k], 'timediff' => $_tzone_new_date->format('P'), 'timezone_offset' => $_tzone_new_date->format('Z')/60, //minutes 'text' => "(GMT" .$_tzone_new_date->format('P') .") " .$_all_timezone_identifiers[$k] ); //BY CONTINENT if($data_type === true) $TIMEZONE_LIST[$_tzone_group][] = $tzone_arr; else $TIMEZONE_LIST[] = $tzone_arr; } //BY TIMEZONE: "America/New_York" if(is_string($data_type)){ $key = array_search($data_type, array_column($TIMEZONE_LIST, 'timezone')); $TIMEZONE_LIST = $key !== false ? $TIMEZONE_LIST[$key] : null; } return $TIMEZONE_LIST; } /*--------------------------------*/Спасибо.
