用 PHP 生成时区的下拉列表

小开

第一个选项允许您从 $_ POST [‘ whateveroucalthesselect’]获取值并将其添加到 UTC。或者甚至存储该值，然后在以后需要时总是调用 UTC + userTZ 设置。对我来说很简单。如果时区频繁变化，最后一个选项将更有价值。

小开

不是这些，而是用 PHP 准备一个带有时区的数组

$arr[0] = "(GMT+02:00) Harare, Pretoria";
$arr[1] = "(GMT+03:00) Jerusalem";

或者

$arr[0] = array("America/Campo_Grande", "(GMT+02:00) Harare, Pretoria");
$arr[1] = array("America/Israel", "(GMT+03:00) Jerusalem");

然后根据这个数组生成表单:

foreach ($arr as $k => $v)
$str .= "<option value=$k>$v[1]</option>";

然后，您可以轻松地切换不同的格式，只需在上面一行代码中进行修改。此外，验证将更加容易，而且不需要正则表达式。只需将 POST 或 GET 发送的值与数组进行比较。现在很容易设置 $arr [ $value _ send _ by _ form ][0]保存 PHP 兼容值，而 $arr [ $value _ send _ by _ form ][1]用户友好值。

最佳答案

我会在 PHP 中做到这一点，除非我会避免做 preg _ match 100的一些次数，并做到这一点，以生成您的列表。

$tzlist = DateTimeZone::listIdentifiers(DateTimeZone::ALL);

此外，我会使用 PHP 的名称的’时区’，忘记了 GMT 偏移量，这将根据 DST 的变化。 Phpbb 中这样的代码只是 b/c 的一种方式，它们仍然支持 PHP4，并且不能依赖于存在的 DateTime 或 DateTimeZone 对象。

我会用下面的代码来做这件事，它与已接受的答案相似(我知道代码可以被重构:) :

    $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');


}

它会产生这样的东西:

<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>
<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>

希望这对你有所帮助，或者激励你做出更好的选择。

您可以从这个数组中创建一个非常简单的下拉菜单(将它放在一起并进行测试是一项非常耗时的任务)。我们已经在一些应用程序中使用了这个列表。

在数据库中存储时区标识符是 非常重要，而不仅仅是像“ GMT + 2”这样的时区偏移量，因为夏令时。

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;
}

这将生成一个类似如下的数组:

[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
…

它目前是按偏移量排序的，但是您可以通过使用 ksort()而不是 asort()轻松地按时区名称排序。

编辑 Tamas 的回答，删除 php.net 站点说不应该再使用的所有“其他”条目。

也许没有关系，但是只要遵循最佳实践就可以了

此外，尽管这份名单将亚速尔群岛列为格林尼治标准时间 -1，但实际上我认为它与格林尼治标准时间相同(至少有时候是这样) ，但我不确定。

通过编辑在 sql 中提供这一功能，以便您可以在表单中创建下拉列表，并将用户的答案绑定到索引。

再次编辑以删除前导空间

我知道这已经有了一个答案，但我看到了一个机会来改进这里的一个答案。Toland H 发布了一些非常好的代码，完全符合问题的要求。下面是 Toland H 代码的缩写和扩展版本:

该函数将所有内容放置在选项标签中。只需回显出在选择标签之间返回的内容。
主要改进: 该列表首先按大陆进行排序，然后根据大陆按选项组进行组织。让它非常用户友好的游客选择他们的时区。

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>";

然后，您需要做的就是回显出在 html 选择标记之间返回的内容。你会得到一个如下的选择列表:

----- 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

诸如此类。

尽管已经有了很多答案，我还是对这个问题提出了另一个解决方案:

时区列表是动态生成的，因此当时区可能发生变化时会自动更新(在 PHP 中)。
时区名称被美化了，例如，“美国/圣巴特勒米”变成了“美国，St. Barthelemy”。
时区按偏移量和名称排序。Toland 的回答只对偏移量进行排序，导致相同偏移量内的时区组未排序。
不从 DateTimeZone::listAbbreviations检索偏移量信息，因为该方法也返回历史时区信息历史时区信息。法维奥的回答确实使用这种方法，这会导致不正确的(历史)偏移量
时区列表仅在首次请求时生成(并使用静态变量“缓存”)。

完整代码如下:

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;
}

这是一个输出的例子

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
...
)

对于每一个区域，使用 list缩写()是没有意义的，因为它返回历史上在那里使用过的所有不同的偏移量，而不仅仅是当前的偏移量。列表的正确基础源肯定是 listIdentifier ()。

我将只生成一次列表并保存它，以避免为每个请求生成它。我可以每个月刷新一次。

另外，我可以将所有的时区信息放到一个单独的 js-script 中，并在客户端生成选择列表本身。Js-script 也可以缓存，时区不会经常更改。

另外，在客户端使用 javascript，你可以知道当前的本地时间，因此你可以找到现在有相同时间的区域(分钟可能不同，所以比较应该是近似的) ，并显示在列表的顶部，这样用户就不必滚动所有的400项。还可以在下面显示相邻区域(+/-1小时)。

也请看这个例子

<?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>";
}
?>

在一些项目中，拥有非洲、欧洲或太平洋的详细时区是没有意义的。所以这里有一个简短的版本

$timezoneTable = array(
"-12" => "(GMT -12:00) Eniwetok, Kwajalein",
"-11" => "(GMT -11:00) Midway Island, Samoa",
"-10" => "(GMT -10:00) Hawaii",
"-9" => "(GMT -9:00) Alaska",
"-8" => "(GMT -8:00) Pacific Time (US &amp; Canada)",
"-7" => "(GMT -7:00) Mountain Time (US &amp; Canada)",
"-6" => "(GMT -6:00) Central Time (US &amp; Canada), Mexico City",
"-5" => "(GMT -5:00) Eastern Time (US &amp; Canada), Bogota, Lima",
"-4" => "(GMT -4:00) Atlantic Time (Canada), Caracas, La Paz",
"-3.5" => "(GMT -3:30) Newfoundland",
"-3" => "(GMT -3:00) Brazil, Buenos Aires, Georgetown",
"-2" => "(GMT -2:00) Mid-Atlantic",
"-1" => "(GMT -1:00) Azores, Cape Verde Islands",
"0" => "(GMT) Western Europe Time, London, Lisbon, Casablanca",
"1" => "(GMT +1:00) Brussels, Copenhagen, Madrid, Paris",
"2" => "(GMT +2:00) Kaliningrad, South Africa",
"3" => "(GMT +3:00) Baghdad, Riyadh, Moscow, St. Petersburg",
"3.5" => "(GMT +3:30) Tehran",
"4" => "(GMT +4:00) Abu Dhabi, Muscat, Baku, Tbilisi",
"4.5" => "(GMT +4:30) Kabul",
"5" => "(GMT +5:00) Ekaterinburg, Islamabad, Karachi, Tashkent",
"5.5" => "(GMT +5:30) Bombay, Calcutta, Madras, New Delhi",
"6" => "(GMT +6:00) Almaty, Dhaka, Colombo",
"7" => "(GMT +7:00) Bangkok, Hanoi, Jakarta",
"8" => "(GMT +8:00) Beijing, Perth, Singapore, Hong Kong",
"9" => "(GMT +9:00) Tokyo, Seoul, Osaka, Sapporo, Yakutsk",
"9.5" => "(GMT +9:30) Adelaide, Darwin",
"10" => "(GMT +10:00) Eastern Australia, Guam, Vladivostok",
"11" => "(GMT +11:00) Magadan, Solomon Islands, New Caledonia",
"12" => "(GMT +12:00) Auckland, Wellington, Fiji, Kamchatka"
);


echo "<select>";
foreach ($timezoneTable as $k => $v){
$sel = ($k==-5)?" selected":"";
echo "<option value='".$k."'".$sel.">".$v."</option>";
}
echo "</select>"

这将生成如下选择:

下面是一个创建的多维数组，按偏移量和尼斯化名称排序:

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>';
}

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;
}

当当当！就这么简单。提供一个数组，其键为 PHP 时区，值为格式为 +-Hours: Minutes 的字符串

这是我整理的一个类，混合了我认为是所有建议中最好的一个，并且以碳作为一个依赖:

namespace App\Support;


use Carbon\Carbon;
use DateTimeZone;


class Timezone
{
protected static $timezones;


public static function all(): array
{
if (static::$timezones) {
return static::$timezones;
}


$offsets   = [];
$timezones = [];


foreach (DateTimeZone::listIdentifiers() as $timezone) {


$offsets[]            = $offset = Carbon::now()->timezone($timezone)->offset;
$timezones[$timezone] = static::formatTimezoneDisplay($timezone, $offset);


array_multisort($offsets, $timezones);


}


return static::$timezones = $timezones;
}


protected static function formatTimezoneDisplay(string $timezone, string $offset): string
{
return static::formatOffset($offset) . ' (' . static::formatTimezone($timezone) . ')';
}


protected static function formatOffset(string $offset): string
{
if (!$offset) {
return 'UTC±00:00';
}


$hours   = intval($offset / 3600);
$minutes = abs(intval($offset % 3600 / 60));


return 'UTC' . sprintf('%+03d:%02d', $hours, $minutes);
}


protected static function formatTimezone(string $timezone): string
{
return str_replace(['/', '_', 'St '], [', ', ' ', 'St. '], $timezone);
}
}

您只需使用 Timezone:all()，就可以得到一个 UTC-5:00 (America, New York)格式的数组，因此您可以轻松地在前端显示选择字段。

我使用相应的 jQuery 插件为此创建了一个 PHP 类。我已经在 https://github.com/peterjtracey/timezoneWidget开源了—— PHP 代码的灵感来自另一个 stackoverflow 的答案，但我认为更优雅。JQuery 插件为选择时区提供了一个很好的界面。

对于那些使用 CodeIgniter 的用户，有一个内置的日期助手功能称为 < strong > timezone _ menu :

$this->load->helper('date');
echo timezone_menu('GMT', 'form-control', 'dropdown-name', ['id' => 'ci-timezone']);

产生以下产出:

php -r "echo json_encode(array_combine(DateTimeZone::listIdentifiers(DateTimeZone::ALL), DateTimeZone::listIdentifiers(DateTimeZone::ALL)));" > list-of-timezones.json

小开

我想把这个想法留在这里:

/*----------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;
}

如果不希望依赖于静态时区列表，或者希望显示偏移量和时区。

这是我想到的

function timezones()
{
$timezones = \DateTimeZone::listIdentifiers();
$items = array();
foreach($timezones as $timezoneId) {
$timezone = new \DateTimeZone($timezoneId);
$offsetInSeconds = $timezone->getOffset(new \DateTime());
$items[$timezoneId] = $offsetInSeconds;
}
asort($items);
array_walk ($items, function (&$offsetInSeconds, &$timezoneId) {
$offsetPrefix = $offsetInSeconds < 0 ? '-' : '+';
$offset = gmdate('H:i', abs($offsetInSeconds));
$offset = "(GMT${offsetPrefix}${offset}) ".$timezoneId;
$offsetInSeconds = $offset;
});
return $items;
}

结果如下

这里重复了@Jonathan 给出的答案(2021年新鲜) ，并包含了自动选择时区的 javascript/jquery。我喜欢它的原因是: a)它自动选择用户的时区; b)如果他们想改变时区，他们会得到一个按字母顺序排列的可读列表，这样就可以很容易地扫描他们的国家，然后是城市。

在大多数情况下，用户不需要更改它，因为它将使用 javasdcript 正确地自动选择。

PHP 来构建选择器数据:

function timezonePickerData() {
static $timezones = null;
if ($timezones === null) {
$timezones = [];
$offsets = [];
$now = new \DateTime('now', new \DateTimeZone('UTC'));
foreach (\DateTimeZone::listIdentifiers(\DateTimeZone::ALL) as $timezone) {


// Calculate offset
$now->setTimezone(new \DateTimeZone($timezone));
$offsets[] = $offset = $now->getOffset();


// Display text for UTC offset
$hours = intval($offset / 3600);
$minutes = abs(intval($offset % 3600 / 60));
$utcDiff = 'UTC' . ($offset ? sprintf('%+03d:%02d', $hours, $minutes) : '');


// Display text for name
$name = str_replace('/', ', ',$timezone);
$name = str_replace('_', ' ', $name);
$name = str_replace('St ', 'St. ', $name);


$timezones[$timezone] = "$name ($utcDiff)";
}
}


return $timezones;
}

HTML/PHP 来构建选择器:

<select id="timezone">
<?php
foreach(timezonePickerData() as $timezone => $location) {
print "<option value=\"$timezone\">$location</option>\n";
}
?>
</select>

JQuery 自动选择用户时区:

var data = Intl.DateTimeFormat().resolvedOptions()
$("#timezone").val(data.timeZone);

下面是自动选择的选择器格式(未单击) :

America, Los Angeles (UTC-7:00)

当用户单击以更改其时区(易于用户扫描)时，选择列表如下所示:
