PHPタイムゾーンリスト
<select>で表示するタイムゾーンのリストを生成する方法を探しています PHPでタイムゾーンのドロップダウンリストを生成する
$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');
$data[] = $zone;
$offset[] = $z->getOffset($c);
$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');
}
私の国をチェックしたとき、オフセットは間違っていました。私はアジア/シンガポールにいます。UTC/ GMT +8でなければなりません http://www.timeanddate.com/worldclock/city.html?n=236 しかし、生成されたリストによると、+ 9です。何らかの論理エラーがありますか？時間は正しかった
このリストを生成するより良い方法はありますか？上記のリンクの同じ質問から、
static $regions = array(
'Africa' => DateTimeZone::AFRICA,
'America' => DateTimeZone::AMERICA,
'Antarctica' => DateTimeZone::ANTARCTICA,
'Aisa' => DateTimeZone::ASIA,
'Atlantic' => DateTimeZone::ATLANTIC,
'Europe' => DateTimeZone::EUROPE,
'Indian' => DateTimeZone::INDIAN,
'Pacific' => DateTimeZone::PACIFIC
);
foreach ($regions as $name => $mask) {
$tzlist[] = DateTimeZone::listIdentifiers($mask);
}
これは、たとえば、わかりやすい表示名が必要な識別子を取得するだけです。 UTC + 8アジア/シンガポールまたは類似のもの。どうすれば入手できますか？
Select要素用に特別に作成したタイムゾーンの配列を取得します。これは、キーがPHPタイムゾーンであり、値が人間の表現である配列に関連付けられています。これは次のとおりです。

夏時間のため、「GMT + 2」のようなタイムゾーンオフセットだけでなく、データベースにタイムゾーン識別子を保存することは非常に重要です。
私はJiew MengとTamásPapの両方のリストを使用し、それぞれについてPHPタイムゾーン識別子のサポート（PHPは世界が知らないものをサポートします））を作成し、複合リストを作成しました。両方のリストとPHPによるサポートがありましたが、Geonames citys DBで使用されるものを選択した異なる識別子がありました。結果は以下のとおりです。

使いやすいタイムゾーンリストを作成するという同じ問題が発生しました。だから私はgeoip（http://freegeoip.net）を使用してユーザーの国を取得し、次に使用しています：
$nearest_time_zones = DateTimeZone::listIdentifiers(DateTimeZone::PER_COUNTRY, $country_code);
リストは一般的に非常に短いため、これは素晴らしいことです。ただし、ユーザーが別のゾーンを指定する場合は、DateTimeZone :: listIdentifiers（）からリスト全体を追加します。すべてのタイムゾーンを表示しない場合、リストされていないタイムゾーンのユーザーがいることになります。
結果のドロップダウンは次のようになります（もちろん、これよりもずっと長いです）：
<optgroup label="Nearest">
<option value="blah/blah">(+5:00) Blah/Blah</option>
...
</optgroup>
<optgroup label="-11:00">
<option value="Pacific/Apia">(-11:00) Pacific/Apia</option>
<option value="Pacific/Midway">(-11:00) Pacific/Midway</option>
<option value="Pacific/Niue">(-11:00) Pacific/Niue</option>
<option value="Pacific/Pago_Pago">(-11:00) Pacific/Pago_Pago</option>
</optgroup>
<optgroup label="-10:00">
<option value="America/Adak">(-10:00) America/Adak</option>
<option value="Pacific/Fakaofo">(-10:00) Pacific/Fakaofo</option>
<option value="Pacific/Honolulu">(-10:00) Pacific/Honolulu</option>
<option value="Pacific/Johnston">(-10:00) Pacific/Johnston</option>
<option value="Pacific/Rarotonga">(-10:00) Pacific/Rarotonga</option>
<option value="Pacific/Tahiti">(-10:00) Pacific/Tahiti</option>
</optgroup>
このアプリケーションはまだ開発中であり、ユーザーからのフィードバックはまだありませんので、これが成功したアプローチであるとは言えません。しかし、geoipアプローチは言及する価値があると思いました。
この方法はオペレーティングシステムに依存しており、常に機能するように、配列/データベースにエキサイティングなタイムゾーンを格納するだけでなく、かなりの作業になる可能性がある夏時間を考慮する必要があります
sourece http://en.wikipedia.org/wiki/Time_zone ：PHP
DateTimeオブジェクトと関連関数は5.2以降、PHPコアにコンパイルされています。これには、デフォルトのスクリプトタイムゾーンを取得および設定する機能が含まれ、DateTimeは内部で独自のタイムゾーンを認識します。ネットはこれに関する広範なドキュメントを提供します。[20]そこに記載されているように、最新のタイムゾーンデータベースはPECL timezonedbを介して実装できます。
自分でデータベースを作成するか、PECL timezonedbを使用してください
以下の画像に示すような類似のタイムゾーンリストを生成する場合
次のphpコードを使用して、 DateTimeZone :: listIdentifiers -timezone_identifiers_listを使用してドロップダウンリストを生成できます。定義済みのすべてのタイムゾーン識別子を含む数値インデックス配列を返します。可能な値すべてのリストが必要な場合（下位互換性のあるエイリアスを含む）、DateTimeZone::ALL_WITH_BC 代わりに DateTimeZone::ALL
echo "<select>";
$tzlist = DateTimeZone::listIdentifiers(DateTimeZone::ALL);
foreach($tzlist as $value)
{
echo "<option value=". $value .">". $value ."</option>";
}
echo "<select>";
PHPでグリニッジ標準時を取得するにはどうすればよいですか？ の次のコードを試してください。私は自分のアプリの1つで使用していますが、マークアップを変更して、好きなものを表示できます。
public function tz_list() {
$zones_array = array();
$timestamp = time();
foreach(timezone_identifiers_list() as $key => $zone) {
date_default_timezone_set($zone);
$zones_array[$key]['zone'] = $zone;
$zones_array[$key]['offset'] = (int) ((int) date('O', $timestamp))/100;
$zones_array[$key]['diff_from_GMT'] = 'UTC/GMT ' . date('P', $timestamp);
}
return $zones_array;
}
次に：
<select name="timezone" id="timezone" class="form-control">
<option value="">Select a time zone</option>
<?php foreach(tz_list() as $t) { ?>
<option value="<?php echo $t['offset']; ?>___<?php echo $t['zone']; ?>"
<?php echo $t['diff_from_GMT'] . ' - ' . $t['zone']; ?></option>
<?php } ?>
</select>
これを試して：
<?php
/**
* Timezones list with GMT offset
*
* @return array
* @link http://stackoverflow.com/a/9328760
*/
function tz_list() {
$zones_array = array();
$timestamp = time();
foreach(timezone_identifiers_list() as $key => $zone) {
date_default_timezone_set($zone);
$zones_array[$key]['zone'] = $zone;
$zones_array[$key]['diff_from_GMT'] = 'UTC/GMT ' . date('P', $timestamp);
}
return $zones_array;
}
?>
<div style="margin-top: 20px;">
<select style="font-family: 'Courier New', Courier, monospace; width: 450px;">
<option value="0">Please, select timezone</option>
<?php foreach(tz_list() as $t) { ?>
<option value="<?php print $t['zone'] ?>">
<?php print $t['diff_from_GMT'] . ' - ' . $t['zone'] ?>
</option>
<?php } ?>
</select>
</div>

オフセットは動的に計算されるため、これはハードコーディングされた配列よりも優れたソリューションです。
<?php
function toGmtOffset($timezone){
$userTimeZone = new DateTimeZone($timezone);
$offset = $userTimeZone->getOffset(new DateTime("now",new DateTimeZone('GMT'))); // Offset in seconds
$seconds = abs($offset);
$sign = $offset > 0 ? '+' : '-';
$hours = floor($seconds / 3600);
$mins = floor($seconds / 60 % 60);
$secs = floor($seconds % 60);
return sprintf("(GMT$sign%02d:%02d)", $hours, $mins, $secs);
}
