php - 国コードを変換する

Question

国コードにはいくつかの方法があります。

このページのように、3文字のコードのリストがあります。

http://www.fina.org/H2O/index.php?option=com_content&view=category&id=93:asia&Itemid=638&layout=default

それらを2文字に変換する簡単な方法はありますか？ポルトガルの「POR」の「PT」のように。

2文字の標準-http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2

ありがとう。

http://country.io/dataから取得できる便利なデータファイルがいくつかあります。

http://country.io/iso3.json-ISO2からISO3の国コードのマップ
http://country.io/names.json-ISO2国コードから国名へのマップ

3文字のコードから2文字のコードに変更したい場合は、最初のマップを反転して使用できます。ただし、ファイルを組み合わせることで、3文字のコードから国名に直接移動するマップを作成できます。簡単なPHPの例を次に示します。

$codes = json_decode(file_get_contents('http://country.io/iso3.json'), true);
$names = json_decode(file_get_contents('http://country.io/names.json'), true);
$iso3_to_name = array();
foreach($codes as $iso2 => $iso3) {
    $iso3_to_name[$iso3] = $names[$iso2];
}

echo $names("PL"); // => "Poland"
echo $iso3_to_map("POL"); // => "Poland"

質問は7年前に行われたようです。今日、私は同様の問題を抱えており、1つの良い解決策を見つけました。この回答が、将来同じ問題を抱える他の人に役立つことを願っています。

使用できる別のライブラリがありますhttps://github.com/thephpleague/iso3166

そうすれば、解決策は簡単になります。$ alpha3は、国の3文字の表現です。そしてalpha2は国の2文字の表現です。

$ composer require league/iso3166
$data = (new League\ISO3166\ISO3166)->alpha3($alpha3);

データは次のようになります。

[
  'name' => 'Netherlands',
  'alpha2' => 'NL',
  'alpha3' => 'NLD',
  'numeric' => '528',
  'currency' => [
    'EUR',
    ]
]

$countryCodeInTwoChar = $data['alpha2']

実際のルックアップを行わずに、簡単な方法はありません。AFG（アフガニスタン）がAFになり、AND（アンドラ）がADになり、BLR（ベラルーシ）がBYになります...したがって、変換するための単純な文字操作を行うことはできません。

私の提案は、国コードテーブルを使用するか、既存のテーブルに列を追加して、両方のコードを保持することです。

これに取り組む人のために、私はalpha3をalpha2にマッピングするJSONを作成しました。ここからダウンロード：https ：//api.myjson.com/bins/1y2hn

したがって、このJSONをオブジェクト（countryCodesの例）に割り当てるだけです。現在、変換は次のとおりです。 countryCodes["US"] //"USA"

上記の他の回答のほとんどは直接的な回答ではありません。私が試してみましょう

APIを使用して3文字を2文字の国コードに変換する以下のコードを試しました：

<?php
    $list=["BWA","SLV","TZA","BRB","IND","BES","ANT"];
    $iso3=file_get_contents('http://country.io/iso3.json');//load the country codes
    $iso3=json_decode($iso3,true);//convert json to associative array
    foreach($list as $k)
    {
        if($k=="ANT")//not defined in code list
            echo "AN";
        else
            echo array_search($k,$iso3); 
        echo "<br/>";
    }
?>

提供される国コードは、2-iso（key）：3-iso（value）の形式です。したがって、キーを検索する代わりに、値で検索し、成功した場合は最初の対応するキーを返します。

これは時間のかかる面倒な方法かもしれませんが、永久に保持できる関数を作成する価値があるかもしれません。おそらく、これは正しい方向を示すことができます。

<?php
function myCodes($in, $type){
$out = "";
$long = array('portugal', 'united kingdom');
$short = array('pt', 'uk');
$in = strtolower(trim($in));
switch($type){
case 'long':$out = str_replace($short, $long, $in);break;
case 'short':$out = str_replace($long, $short, $in);break;
}
echo $out;
}

echo myCodes('United Kingdom', 'short'); //this will echo 'uk'
echo myCodes('UK', 'long'); //this will echo 'united kingdom'

?>

もちろん、これには、長い配列と短い配列が位置的に一致していることを確認するなど、いくつかの欠点があります。また、機能も維持する必要があります。

国の名前に特別な計画がないので、簡単な方法はありません。たとえばPT、PORforPortugalとこれは他の国でも異なる場合があります。国ごとに2文字を保持する配列を作成することをお勧めします。

例：

$countries = array('PT' => 'Portugal', 'UK' => 'United Kingdom');
