Liste des fuseaux horaires PHP

Je suis à la recherche d'un moyen de générer une liste de fuseaux horaires pour l'affichage dans un <select> Générer une liste de fuseaux horaires avec PHP

    $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');

}

Quand j'ai vérifié mon pays, le décalage était faux, je suis en Asie / Singapour, il devrait être UTC / GMT + 8 http://www.timeanddate.com/worldclock/city.html?n=236 mais selon la liste générée son + 9. Y a-t-il une sorte d'erreur logique? Le temps était correct tho

Est-il un meilleur moyen de générer cette liste? à partir de la même question dans le lien ci-dessus,

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);
}

Cela obtient juste les identifiants que je veux un nom d'affichage amical par exemple. UTC + 8 Asie / Singapour ou quelque chose de similaire. Comment je peux avoir ça?

Prenez mon tableau de fuseaux horaires, que j'ai fait spécialement pour select element. C'est un tableau associé où la clé est le fuseau horaire PHP et la valeur est la représentation humaine. C'est ça:

Il est très important de stocker les identifiants de fuseau horaire dans votre base de données et pas seulement le décalage de fuseau horaire comme "GMT + 2", en raison de L'heure D'été.

score 3 · Answer 3

Je viens d'avoir le même problème de faire une liste de fuseaux horaires facile à utiliser. J'utilise donc geoip (http://freegeoip.net) pour obtenir le pays de l'utilisateur, puis en utilisant:

$nearest_time_zones = DateTimeZone::listIdentifiers(DateTimeZone::PER_COUNTRY, $country_code);

C'est génial car la liste est généralement très courte. Mais dans le cas où l'utilisateur veut spécifier une zone différente, j'ajoute la liste entière de DateTimeZone::listIdentifiers (). Si vous n'affichez pas tous les fuseaux horaires, vous devez avoir un utilisateur d'un fuseau horaire qui n'est pas répertorié.

La liste déroulante résultante semble comme ça (bien sûr c'est beaucoup plus long que ça):

<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>

Essayez le code suivant à partir de Comment obtenir le temps moyen de Greenwich en PHP?. Je l'utilise sur une de mes applications, mais vous pouvez changer les balises pour afficher ce que vous voulez:

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;
}

Puis:

<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>

J'ai utilisé les deux listes de Jiew Meng et Tamás Pap, pour chacune j'ai vérifié le support PHP de timezone identifier (PHP supporte moins que le monde ne le sait), et fait une liste composite. Pour ces fuseaux horaires qui étaient dans les deux listes et avaient un support par PHP mais avaient des identifiants différents, j'ai sélectionné ceux qui sont utilisés dans GeoNames cities DB. Le résultat est ci-dessous:

Cette méthode repose sur votre système d'exploitation, pour qu'il fonctionne toujours, il suffit de stocker les fuseaux horaires dans un tableau/base de données, vous devez également prendre en compte le daylightsavingstime (s) qui peut être un peu de travail

Sourece http://en.wikipedia.org/wiki/Time_zone: PHP

Les objets DateTime et les fonctions associées ont été compilés dans le noyau PHP depuis la version 5.2. Cela inclut la possibilité d'obtenir et de définir le fuseau horaire du script par défaut, et DateTime est conscient de son propre fuseau horaire en interne. PHP.net fournit une documentation complète à ce sujet.[20] comme indiqué ici, la base de données de fuseau horaire la plus récente peut être implémentée via le PECL timezonedb.

Donc, soit créez la base de données vous-même, soit utilisez le PECL timezonedb

Si vous cherchez à générer une liste de fuseaux horaires similaire à celle indiquée dans l'image ci-dessous

Vous pouvez utiliser le code php suivant pour générer la liste déroulante en utilisant DateTimeZone:: listIdentifiers -- timezone_identifiers_list-retourne un tableau indexé numériquement contenant tous les identificateurs de fuseau horaire définis.Si vous voulez une liste de toutes les valeurs possibles (y compris les alias rétrocompatibles), utilisez DateTimeZone::ALL_WITH_BC à la place de DateTimeZone::ALL

echo "<select>";
$tzlist = DateTimeZone::listIdentifiers(DateTimeZone::ALL);
foreach($tzlist as $value)
{
  echo "<option value=". $value .">". $value ."</option>";
}
echo "<select>";

                  $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);
