How can I get list of supported calendars, timezones, locales in PHP ICU (intlDateFormatter)?

推荐答案

如何使用 PHP intl 模块创建语言环境、日历和时区数组

要为所有语言环境创建资源包:

To create a resource bundle for all locales:

$bundle=new ResourceBundle('','ICUDATA');

要列出包中的资源名称:

To list the resource names in the bundle:

$rnames=[];
foreach($bundle as $n=>$v){$rnames[]=$n;}

产生:

AuxExemplarCharacters
Ellipsis
ExemplarCharacters
ExemplarCharactersNumbers
ExemplarCharactersPunctuation
MoreInformation
NumberElements
Version
calendar
characterLabel
delimiters
fields
layout
listPattern
measurementSystemNames
parse

获取所有语言环境的数组:

To get an array of all locales:

$locales=$bundle->getLocales('');

产生:

af
af_NA
af_ZA
agq
agq_CM
ak
ak_GH
...
gv_IM
ha
ha_GH
ha_NE
ha_NG
haw
...
zh_Hant
zh_Hant_HK
zh_Hant_MO
zh_Hant_TW
zu
zu_ZA

获取所有日历名称的数组:

To get an array of all calendar names:

$cnames=[];
$calendars=$bundle->get('calendar');
foreach($calendars as $n=>$v){$cnames[]=$n;}

产生:

buddhist
chinese
coptic
dangi
default
ethiopic
ethiopic-amete-alem
generic
gregorian
hebrew
indian
islamic
islamic-civil
islamic-rgsa
islamic-tbla
islamic-umalqura
japanese
persian
roc

要列出特定语言环境的日历，请创建如下包:

To list the calendars for a particular locale, create the bundle like:

$bundle=new ResourceBundle('en','ICUDATA');

要列出所有时区:

// CREATE TIMEZONE ITERATOR AND SET TO START
$zones=[];
$zone_iter=IntlTimeZone::createEnumeration(NULL);
$zone_iter->rewind();

// WHILE VALID TIMEZONE
while($zone_iter->valid()){
 // ADD TIMEZONE TO ARRAY
 $zones[]=$zone_iter->current();

 // NEXT TIMEZONE
 $zone_iter->next();
}

生产:

ACT
AET
AGT
ART
AST
Africa/Abidjan
Africa/Accra
Africa/Addis_Ababa
Africa/Algiers
...
Atlantic/South_Georgia
Atlantic/St_Helena
Atlantic/Stanley
Australia/ACT
Australia/Adelaide
Australia/Brisbane
...
US/Pacific
US/Pacific-New
US/Samoa
UTC
Universal
VST
W-SU
WET
Zulu

要获取未弃用的时区列表并从熟悉的区域(如亚洲")开始，请执行以下循环:

To get a list of timezones that are not deprecated and start with the familiar regions like 'Asia', make the loop:

// WHILE VALID TIMEZONE
while($zone_iter->valid()){
 // IF NOT DEPRECATED AND STARTS WITH FAMILIAR REGION NAME
 $zone=$zone_iter->current();
 $tzone=intltz_create_time_zone($zone);
 $czone=$tzone->getCanonicalID($zone);
 if(($zone==$cid)&&
    (preg_match('~^(Af|Am|An|As|At|Au|Eu|In|Pa|Etc/UTC)~',$zone)===1)){
  // ADD TIMEZONE TO ARRAY
  $zones[]=$zone;
 }

 // NEXT TIMEZONE
 $zone_iter->next();
}

生产:

Africa/Abidjan
Africa/Accra
Africa/Addis_Ababa
...
Australia/Perth
Australia/Sydney
Etc/UTC
Europe/Amsterdam
Europe/Andorra
...
Pacific/Truk
Pacific/Wake
Pacific/Wallis

请注意，它包含了 UTC 的规范名称作为 Etc/UTC.

Note that it includes the canonical name for UTC as Etc/UTC.

要列出特定国家/地区的时区，请创建如下迭代器:

To list the timezones for a particular country, create the iterator like:

$zone_iter=IntlTimeZone::createEnumeration('AU');

请注意，生成所有列表的时间不到 20 毫秒，包括原始和过滤后的时区列表.

Note that it took less than 20ms to generate all lists, including the raw and filtered timezone lists.
