Membuat daftar zona waktu drop down dengan PHP


141

Sebagian besar situs memerlukan cara untuk menampilkan tanggal di situs di zona waktu yang disukai pengguna. Di bawah ini adalah dua daftar yang saya temukan dan kemudian satu metode menggunakan PHP DateTime bawaan kelas di PHP 5.

Saya perlu bantuan untuk mengetahui yang mana di antara yang terbaik untuk dicoba ketika mencoba mendapatkan offset UTC dari pengguna saat mendaftar.

Satu:

<option value="-12">[UTC - 12] Baker Island Time</option>
<option value="-11">[UTC - 11] Niue Time, Samoa Standard Time</option>
<option value="-10">[UTC - 10] Hawaii-Aleutian Standard Time, Cook Island Time</option>
<option value="-9.5">[UTC - 9:30] Marquesas Islands Time</option>
<option value="-9">[UTC - 9] Alaska Standard Time, Gambier Island Time</option>
<option value="-8">[UTC - 8] Pacific Standard Time</option>
<option value="-7">[UTC - 7] Mountain Standard Time</option>
<option value="-6">[UTC - 6] Central Standard Time</option>
<option value="-5">[UTC - 5] Eastern Standard Time</option>
<option value="-4.5">[UTC - 4:30] Venezuelan Standard Time</option>
<option value="-4">[UTC - 4] Atlantic Standard Time</option>
<option value="-3.5">[UTC - 3:30] Newfoundland Standard Time</option>
<option value="-3">[UTC - 3] Amazon Standard Time, Central Greenland Time</option>
<option value="-2">[UTC - 2] Fernando de Noronha Time, South Georgia &amp; the South Sandwich Islands Time</option>
<option value="-1">[UTC - 1] Azores Standard Time, Cape Verde Time, Eastern Greenland Time</option>
<option value="0" selected="selected">[UTC] Western European Time, Greenwich Mean Time</option>
<option value="1">[UTC + 1] Central European Time, West African Time</option>
<option value="2">[UTC + 2] Eastern European Time, Central African Time</option>
<option value="3">[UTC + 3] Moscow Standard Time, Eastern African Time</option>
<option value="3.5">[UTC + 3:30] Iran Standard Time</option>
<option value="4">[UTC + 4] Gulf Standard Time, Samara Standard Time</option>
<option value="4.5">[UTC + 4:30] Afghanistan Time</option>
<option value="5">[UTC + 5] Pakistan Standard Time, Yekaterinburg Standard Time</option>
<option value="5.5">[UTC + 5:30] Indian Standard Time, Sri Lanka Time</option>
<option value="5.75">[UTC + 5:45] Nepal Time</option>
<option value="6">[UTC + 6] Bangladesh Time, Bhutan Time, Novosibirsk Standard Time</option>
<option value="6.5">[UTC + 6:30] Cocos Islands Time, Myanmar Time</option>
<option value="7">[UTC + 7] Indochina Time, Krasnoyarsk Standard Time</option>
<option value="8">[UTC + 8] Chinese Standard Time, Australian Western Standard Time, Irkutsk Standard Time</option>
<option value="8.75">[UTC + 8:45] Southeastern Western Australia Standard Time</option>
<option value="9">[UTC + 9] Japan Standard Time, Korea Standard Time, Chita Standard Time</option>
<option value="9.5">[UTC + 9:30] Australian Central Standard Time</option>
<option value="10">[UTC + 10] Australian Eastern Standard Time, Vladivostok Standard Time</option>
<option value="10.5">[UTC + 10:30] Lord Howe Standard Time</option>
<option value="11">[UTC + 11] Solomon Island Time, Magadan Standard Time</option>
<option value="11.5">[UTC + 11:30] Norfolk Island Time</option>
<option value="12">[UTC + 12] New Zealand Time, Fiji Time, Kamchatka Standard Time</option>
<option value="12.75">[UTC + 12:45] Chatham Islands Time</option>
<option value="13">[UTC + 13] Tonga Time, Phoenix Islands Time</option>
<option value="14">[UTC + 14] Line Island Time</option>

Atau hanya menggunakan PHP itu sendiri:

$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 );

Sepertinya yang terakhir akan menjadi yang paling aman karena akan tumbuh dengan rilis PHP yang digunakan. Anda juga dapat membalik array itu saat diperlukan untuk mengikat zona waktu dengan nama kota.

Komentar tidak membantu, tetapi sebagai penduduk Saskatchewan, saya lebih suka membaca: <option value = "America / Regina"> (GMT-06: 00) Saskatchewan, Amerika Tengah </option> bukan <option value = "America / Belize "> (GMT-06: 00) Saskatchewan, Amerika Tengah </option> :)
Kenton de Jong

Dalam hal UI, saya sarankan untuk meletakkan salinan nilai-nilai yang kemungkinan besar akan digunakan oleh pengguna (berdasarkan audiens target Anda dan / atau deteksi browser) di bagian atas daftar, karena daftar mungkin menghitung hingga ratusan nilai-nilai.
Fabien Snauwaert

Saya akan melakukannya dalam PHP, kecuali saya akan menghindari melakukan preg_match 100 beberapa kali dan melakukan ini untuk menghasilkan daftar Anda.

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

Juga, saya akan menggunakan nama PHP untuk 'zona waktu' dan melupakan offset GMT, yang akan berubah berdasarkan DST. Kode seperti itu di phpbb hanya seperti itu b / c mereka masih mendukung PHP4 dan tidak bisa mengandalkan objek DateTime atau DateTimeZone yang ada di sana.

Menggunakan PHP 5.2.5 saya mengerti Undefined class constant 'AFRICA'ketika saya mencoba menggunakan kelas DateTimeZone. Saya memeriksa kelas yang ditentukan dan terdaftar jadi mungkin windows membutuhkan sesuatu yang lain agar bisa berfungsi.
Xeoncross

Saya telah melaporkan bug untuk kesalahan yang sama dengan Xeoncross dan bertanya-tanya apakah ada yang tahu bagaimana ini mungkin? Manual tampaknya mengindikasikan bahwa konstanta ini tersedia sejak PHP5.2 tetapi apakah ini salah?
brendo

Maaf menggandakan komentar, tetapi saya tidak dapat mengedit komentar saya sebelumnya. Sekadar informasi, sepertinya masalah di sini adalah parameter $ what listIdentifiers hanya ditambahkan di PHP5.3. Sepertinya ini juga ketika konstanta ditambahkan juga, hanya saja saya masih tidak dapat menemukan referensi dalam panduan migrasi ke 5.3 atau dalam log perubahan 5.3.x untuk mendukung ini.
brendo

@brendo: Saya di bawah kesan yang sama, seperti untuk $regionsnilai 1023akan menggantikan semua konstanta itu. Juga, jika Anda membutuhkan ekspresi reguler, pertimbangkan preg_grep()sebagai ganti preg_match().

Diperbarui untuk digunakan DateTimeZone::ALLdaripada membuat array daerah yang tersedia dan mengulanginya.

Mengikuti contoh user210179 di atas, saya telah menulis fungsi berikut untuk membuat saya daftar semua zona waktu dengan offset mereka:

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;
}

Ini akan menghasilkan array yang terlihat seperti:

[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

Saat ini diurutkan berdasarkan offset, tetapi Anda dapat dengan mudah mengurutkan berdasarkan nama zona waktu dengan melakukan ksort()alih-alih asort().


6
Alih-alih menghasilkan array daerah dan beralih melalui mereka, sepertinya Anda sekarang dapat menelepon $timezones = DateTimeZone::listIdentifiers( DateTimeZone::ALL );Jika Anda hanya ingin memasukkan daerah tertentu, Anda dapat menelepon$timezones = DateTimeZone::listIdentifiers( DateTimeZone::AMERICA | DateTimeZone::EUROPE );
Toland Hon

@Nathan Apakah mungkin untuk mengurutkan daftar berdasarkan nilai offset alih-alih teks offset. Maksud saya, alih-alih UTC-11.00,UTC-10.00, ... ,UTC-01.00,UTC+14.00,UTC-13.00, ... ,UTC+00.00, saya ingin menyortirnya sebagaiUTC-11.00,UTC-10.00, ... ,UTC-01.00,UTC+00.00,UTC+01.00, ... ,UTC+13.00,UTC-14.00
Taufik Nurrohman

Saya benar-benar membuat satu perubahan untuk ini, mendapatkannya untuk str_replace garis bawah dengan spasi dalam nilai-nilai, selain itu, kesempurnaan, terima kasih!
James Hunt

array_mergeseharusnya tidak digunakan dalam satu lingkaran.
COil

Kode yang bagus, menginspirasi kelas I open-source di sini: github.com/peterjtracey/timezoneWidget/blob/master/server/php/…

Terlepas dari banyaknya jawaban yang ada, saya telah membuat solusi lain untuk masalah ini. Pro implementasi saya adalah:

  • Daftar zona waktu dihasilkan secara dinamis, dan dengan demikian secara otomatis memperbarui kapan zona waktu mungkin berubah (dalam PHP).
  • Nama zona waktu di-prettified. Misalnya, "Amerika / St_Barthelemy" menjadi "Amerika, St. Barthelemy".
  • Zona waktu diurutkan berdasarkan offset dan nama. Jawaban Toland hanya mengurutkan pada offset, menghasilkan kelompok zona waktu yang tidak disortir dalam offset yang sama.
  • Informasi offset tidak diambil dari DateTimeZone::listAbbreviations , karena metode itu juga mengembalikan informasi zona waktu historis . Jawaban Favio memang menggunakan metode ini, yang menghasilkan offset (historis) yang salah
  • Daftar zona waktu hanya dihasilkan saat pertama kali diminta (dan 'di-cache' menggunakan variabel statis).

Ini kode lengkapnya:

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;
}

Dan inilah contoh outputnya

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
    ...
)

Saya tahu komentar ini adalah beberapa tahun setelah yang terakhir tetapi saya mencoba menerapkan kode Anda sebagai fungsi inti sebagai pengganti ini - github.com/DocWatson/acf-timezone-picker/blob/master/… - awal di line 73. Saya tahu itu tidak mungkin terlalu sulit untuk dicapai tetapi saya tidak tahu di mana saya gagal. Setiap pemikiran akan sangat dihargai!

@ Daveyake Saya sudah meletakkan fungsi saya di kelas Anda, apakah ini bekerja untuk Anda? gist.github.com/jhogervorst/e284f01a960f8ff99b7e8dbf5b11b89a
Jonathan

Ini berhasil, tetapi saya harus mengubah dua baris Anda $timezones = [];ke $timezones = array();dan $offsets = [];ke $offsets = array();.

Saya akan melakukannya dengan kode berikut yang mirip dengan jawaban yang diterima (saya tahu kode tersebut dapat di-refactored :)):

    $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');

}

Ini menghasilkan sesuatu seperti:

<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>

Harapan yang sedikit membantu dan / atau menginspirasi Anda untuk datang dengan sesuatu yang lebih baik.

Terima kasih, semakin banyak opsi semakin baik.
Membuat daftar

Ide yang hebat! Saya mencobanya melalui salin / tempel, dan sementara hasilnya terlihat seperti yang dijelaskan, beberapa offset GMT salah (walaupun waktunya tepat). Misalnya di Musim Dingin (waktu std) America / Detroit menunjukkan offset GMT -6, meskipun pada EST (-5). Ada juga banyak daftar GMT-4, dan bahkan satu GMT-2 (Amerika / Pangnirtung), meskipun mereka semua memiliki waktu yang sama dengan New_York. Masalahnya adalah $ row ['offset'] memiliki offset asli dari listAbbreviations () tidak disesuaikan untuk waktu saat ini. Menambahkan $zone['offset'] = $z->getOffset($c);sebelum $data[] = $zone;mengoreksi offset yang ditampilkan.

Jawaban ini menghasilkan informasi offset yang salah (historis) ! Misalnya, "Eropa / Amsterdam" menunjukkan "GMT + 00: 20", yang tidak lagi digunakan sejak 1940. Silakan lihat jawaban saya di mana saya menjelaskan masalahnya. Gunakan jawaban saya, atau jawaban lain yang tidak bergantung DateTimeZone::listAbbreviations, untuk mendapatkan daftar zona waktu yang benar.

Anda dapat membuat dropdown yang sangat mudah dari array ini (Ini adalah tugas yang memakan waktu untuk menggabungkan ini dan mengujinya). Kami sudah menggunakan daftar ini di beberapa aplikasi kami.

Ini sangat penting untuk menyimpan pengidentifikasi zona waktu di database Anda dan bukan hanya zona waktu yang diimbangi seperti "GMT + 2", karena Daylight Saving Times.

MEMPERBARUI

Saya memperbarui / mengoreksi daftar zona waktu (juga checkout: https://github.com/paptamas/timezones ):

<?php
$timezones = array (
'(GMT-11:00) Midway Island' => 'Pacific/Midway',
'(GMT-11:00) Samoa' => 'Pacific/Samoa',
'(GMT-10:00) Hawaii' => 'Pacific/Honolulu',

Zona waktu mungkin berubah, jadi saya akan merekomendasikan untuk menggunakan daftar zona waktu PHP pada setiap saat (dan tidak menggunakan array hardcode, seperti yang Anda sarankan).

Mengedit jawaban Tamas untuk menghapus semua entri "lain" yang menurut situs php.net seharusnya tidak digunakan lagi.

Mungkin tidak masalah, tetapi hanya mengikuti praktik terbaik. Lihat pemberitahuan di bagian bawah: http://fr2.php.net/manual/en/timezones.others.php

Juga, meskipun daftar ini memiliki Azores sebagai GMT -1, sebenarnya saya pikir itu sama (setidaknya terkadang) dengan GMT, tetapi tidak yakin.

Mengedit untuk menawarkan ini dalam sql sehingga Anda dapat membuat daftar drop-down dalam bentuk dan meminta jawaban pengguna diikat ke indeks sebagai gantinya.

Mengedit lagi untuk menghapus ruang terdepan

Menggunakan listAbbreviations () tidak masuk akal karena untuk setiap area itu mengembalikan semua offset berbeda yang secara historis digunakan di sana, bukan hanya yang saat ini. Sumber dasar yang tepat dari daftar ini jelas listIdentifiers ().

Saya akan menghasilkan daftar sekali saja dan menyimpannya untuk menghindari menghasilkannya untuk setiap permintaan. Saya bisa menyegarkannya sebulan sekali.

Juga, saya bisa memasukkan semua info zona waktu ke skrip js terpisah dan membuat daftar pilih sendiri di sisi klien. Skrip js dapat di-cache juga, zona waktu tidak sering berubah.

Selain itu, menggunakan javascript di sisi klien, Anda dapat mengetahui waktu setempat saat ini, dan karenanya Anda dapat menemukan zona yang memiliki waktu yang sama sekarang (menit mungkin berbeda, jadi perbandingannya harus perkiraan), dan menampilkannya di atas daftar, sehingga pengguna tidak perlu menelusuri semua 400 item. Anda juga dapat menampilkan zona yang berdekatan (+/- 1 jam) berikut.

Saya tahu ini sudah memiliki jawaban tetapi saya melihat peluang untuk memperbaiki salah satu jawaban di sini. Toland H memposting beberapa kode yang sangat bagus yang melakukan persis apa yang diminta pertanyaan itu. Di bawah ini adalah versi singkat dan memperluas kode Toland H:

  • Fungsi ini menempatkan segala sesuatu di tag opsi untuk Anda. Gema lagi apa yang kembali di antara tag pilih Anda.
  • Peningkatan Besar: Daftar ini disortir terlebih dahulu oleh benua dan disusun dalam kelompok opsi berdasarkan benua. Jadikan sangat user friendly bagi pengunjung yang memilih zona waktu mereka.

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>";

Maka yang perlu Anda lakukan adalah mengulang apa yang dikembalikan di antara tag pilih html Anda. Anda akan mendapatkan daftar pilih seperti ini:

----- 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

Dan seterusnya...

Fungsi PHP ini melakukan Pekerjaan untuk Anda dan mengembalikan array:

function time_zonelist(){
    $return = array();
    $timezone_identifiers_list = timezone_identifiers_list();
    foreach($timezone_identifiers_list as $timezone_identifier){
        $date_time_zone = new DateTimeZone($timezone_identifier);
        $date_time = new DateTime('now', $date_time_zone);
        $hours = floor($date_time_zone->getOffset($date_time) / 3600);
        $mins = floor(($date_time_zone->getOffset($date_time) - ($hours*3600)) / 60);
        $hours = 'GMT' . ($hours < 0 ? $hours : '+'.$hours);
        $mins = ($mins > 0 ? $mins : '0'.$mins);
        $text = str_replace("_"," ",$timezone_identifier);
        $return[$timezone_identifier] = $text.' ('.$hours.':'.$mins.')';
    }
    return $return;
}

Fungsi PHP ini mengembalikan array dari semua Zona Waktu yang ada termasuk Offset:

Gunakan misalnya seperti ini:

print_r(time_zonelist());

Bisakah Anda menjelaskan apa fungsinya?

// taken from Toland Hon's Answer
function prettyOffset($offset) {
    $offset_prefix = $offset < 0 ? '-' : '+';
    $offset_formatted = gmdate( 'H:i', abs($offset) );

    $pretty_offset = "UTC${offset_prefix}${offset_formatted}";

    return $pretty_offset;
}

foreach ($timezones as $k => $v) {
    $tz = DateTimeZone::listIdentifiers(DateTimeZone::PER_COUNTRY, $k);

    foreach ($tz as $value) {
        $t = new DateTimeZone($value);
        $offset = (new DateTime("now", $t))->getOffset();
        $timezones[$k]['timezones'][$value] = prettyOffset($offset);
    }   
}

Ini memberi saya array yang dikelompokkan berdasarkan negara:

  }

Yang berarti sekarang saya dapat melakukan sesuatu seperti di bawah ini (tentu saja dengan beberapa tipuan javaScript): Pengaturan Zona Waktu Google Analytics

Hei @ Lucky, bisakah Anda memberi tahu saya bagaimana Anda melakukan ini? Saya tidak bisa mengerti dari asnwer Anda.

Dalam beberapa proyek benar-benar tidak masuk akal untuk memiliki zona waktu terperinci dari Afrika, Eropa atau Pasifik. Jadi ini adalah versi singkatnya

$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>" 

ini akan menghasilkan pilih seperti di bawah ini:

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;
}

Tada! Sesederhana ini. Memberi Anda sebuah array dengan kunci sebagai zona waktu PHP dan nilai sebagai string dalam format + -Jam: Menit

Saya membuat kelas PHP untuk ini dengan plugin jQuery yang sesuai. Saya sudah membuka-sumber di https://github.com/peterjtracey/timezoneWidget - kode PHP terinspirasi oleh jawaban stackoverflow lain, tapi saya pikir jauh lebih elegan. Plugin jQuery memberikan antarmuka yang bagus untuk memilih zona waktu.

Varian 1

Hasil:

...
[America/Scoresbysund] => (UTC+00:00) America/Scoresbysund
[Atlantic/Azores] => (UTC+00:00) Atlantic/Azores
[Atlantic/Reykjavik] => (UTC+00:00) Atlantic/Reykjavik
[Atlantic/St_Helena] => (UTC+00:00) Atlantic/St_Helena
[UTC] => (UTC+00:00) UTC
[Africa/Algiers] => (UTC+01:00) Africa/Algiers
[Africa/Bangui] => (UTC+01:00) Africa/Bangui 
...

Kode:

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

$result = [];
foreach ($tzlist as $timezone) {
    $offset = (new DateTimeZone($timezone))->getOffset(new DateTime);
    $offsetPrefix = $offset < 0 ? '-' : '+';
    $offsetFormatted = gmdate('H:i', abs($offset));

opsi pertama akan memungkinkan Anda mengambil nilai dari $ _POST ['whateveryoucalltheselect'] dan menambahkannya ke UTC. atau bahkan menyimpan nilai itu dan kemudian selalu memanggil UTC + userTZsetting kapan pun Anda membutuhkannya. sepertinya paling mudah bagi saya. opsi terakhir akan jauh lebih berharga jika zona waktu sering berubah.


0

Tidak satupun dari mereka. Alih-alih menyiapkan array dalam PHP dengan zona waktu itu. Suka

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

atau

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

dan seterusnya. Kemudian hasilkan form berdasarkan pada array ini:

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

Dan kemudian Anda dapat dengan mudah beralih dengan format yang berbeda hanya dengan modifikasi kode di baris di atas. Validasi juga akan jauh lebih mudah dan tidak memerlukan ekspresi reguler. Bandingkan saja nilai yang dikirim oleh POST atau GET dengan array. Sekarang mudah untuk mengatur $ arr [$ value_sent_by_form] [0] menyimpan nilai yang kompatibel dengan PHP sementara $ arr [$ value_sent_by_form] [1] nilai ramah pengguna.


Bagaimana Anda tahu zona waktu UTC mana yang akan ditetapkan jika satu-satunya nilai yang Anda miliki adalah kunci numerik dan string ramah manusia? Saya pikir Anda bermaksud mengatur kunci array ke nilai aktual seperti dalam daftar satu. Juga, apa pun yang saya pilih Anda dapat yakin bahwa itu akan menemukan jalannya ke dalam array PHP. ;)
Xeoncross

Kemudian siapkan array seperti ini: $ arr [0] = array ("America / Campo_Grande", "(GMT + 02:00) Harare, Pretoria");

Setelah mencoba semua solusi yang disajikan di sini dan tidak puas, saya telah menemukan skrip yang sesuai dengan kebutuhan saya dan lebih ramah pengguna. Sebagai catatan, saya akan menyimpannya sebagai solusi yang memungkinkan. Saya suka solusi salin / tempel :)

Script mengembalikan pilihan dengan zona waktu apa pun yang Anda inginkan terpilih sebelumnya.

Inilah kelas yang saya kumpulkan, mencampur apa yang saya pikir merupakan saran terbaik di sini, dan dengan Karbon sebagai ketergantungan:

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);
    }
}

Anda cukup Timezone:all(), dan itu membuat Anda array dalam format UTC-5:00 (America, New York), sehingga Anda dapat dengan mudah menampilkan bidang pilih di frontend Anda.

Bagi mereka yang menggunakan CodeIgniter, ada fungsi Date Helper bawaan yang disebut timezone_menu . Ini:

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

Hasilkan keluaran berikut:

Saya melakukan ini:

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

Saya ingin meninggalkan ide ini di sini:

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