Çoğu site bazı kullanıcılar tercih ettikleri zaman diliminde sitesinde tarihlerini göstermek gerekir. Aşağıda two lists PHP 5 I found and sonra bir yöntem using the built in PHP DateTime sınıf.

UTC kayıtlı kullanıcı uzaklığı elde etmek için kullanmaya teşebbüs için en iyi olacağını bilmek için yardıma ihtiyacım var.

Veya PHP kullanarak sadece kendini

$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 );

Son bir PHP sürümü kullanılıyor büyümek gibi güvenli olacak gibi görünüyor. Ayrıca dilimleri bağlamak için gerekli bir dizi etrafında şehir isimleri değiştirirsin.

Preg_match 100 yapıyor bazı zamanlar önlemek ve bu listenizi oluşturmak için yaparım dışında PHP bunu yapmak istiyorum.

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

Ayrıca, PHP için isimlerini 'zaman dilimlerinin DST göre değişecektir.' ve GMT uzaklıklar unut kullanırdım Phpbb içinde böyle bir kodu b/c hala ve DateTime güveniyor ya da nesneleri orada olmak DateTimeZone yok PHP4 destekleyen, ancak bu şekilde olur.
