国家/地区代码有多种方法。
我有一个3个字符的代码列表,如本页所示:
http://www.fina.org/H2O/index.php?option=com_content&view=category&id=93:asia&Itemid=638&layout=default

**是否有简单的方法将其转换为2个字符?**如葡萄牙语“POR”中的“PT”。

2个字符的标准-http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2
谢谢。

您可以从http://country.io/data中获取一些有用的数据文件,这些文件将对您有所帮助:

如果你只想从3个字母的代码转换成2个字母的代码,你可以翻转第一张Map并使用它。你也可以通过组合文件来创建一张从3个字母的代码直接转换成国家名称的Map。下面是一个简单的PHP示例:

$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"

我看到七年前有人问过这个问题,今天我遇到了类似的问题,找到了一个很好的解决办法,希望这个答案对以后遇到同样问题的人有帮助。
有一个单独的库,可用于https://github.com/thephpleague/iso3166
那么解决方案就很简单了。$alpha3是一个国家的三个字符的表示,而alpha2是这个国家的两个字符的表示。

  1. $ composer require league/iso3166
  2. $data = (new League\ISO3166\ISO3166)->alpha3($alpha3);
    1.数据如下所示:
[
  'name' => 'Netherlands',
  'alpha2' => 'NL',
  'alpha3' => 'NLD',
  'numeric' => '528',
  'currency' => [
    'EUR',
    ]
]
  1. $countryCodeInTwoChar = $data['alpha2']

如果不进行实际的查找,就没有简单的方法:AFG(阿富汗)变成AF,AND(安道尔)变成AD,BLR(白俄罗斯)变成BY......所以你不能做任何简单的字符操作来转换。
我的建议是使用一个国家代码表,或者在任何现有的表中添加一个额外的列,这样您就可以同时拥有这两个代码。

以上其他答案大多数都不是直接答案,让我试试
我已尝试使用API以下代码将3个字符转换为2个字符的国家/地区代码

<?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/>";
    }
?>

提供的国家代码是2-iso(key):3-iso(value)的形式,所以我不是搜索key,而是按value搜索,如果成功,则返回第一个对应的key。

虽然这可能是一个冗长而痛苦的方法,但它可能非常值得你编写一个可以永远保存的函数,也许这可以为你指明正确的方向:

<?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'

?>

这当然会有一些缺点,比如要确保长数组和短数组的位置匹配,并且您还需要维护该函数。

$Map['POR'] = 'PT';
$短码= $Map[$长码];

在ruby中,你可以这样做:(从http://download.geonames.org/export/dump/获取国家信息. txt)

require 'csv'
countries_iso3_map = {}
CSV.foreach('countryInfo.txt',:col_sep=>'   ',:row_sep =>:auto) do |row|
   next if row[0][0] == '#' #ignore comments section
   countries_iso3_map[row[0][0,2]]= row[1][0,3]
end
p countries_iso3_map['PT']

这不是一个简单的方法,因为国家名称中没有特定的方案。例如,PT from POR for Portugal,这对于其他国家也可能不同。您可能需要创建一个数组,为每个国家保存两个字母。

    • 示例:**
$countries = array('PT' => 'Portugal', 'UK' => 'United Kingdom');
