使用 PHP 将国家语言名称转换为 ISO 代码首字母

问题描述

对于工作表，我正在寻找一种方法来获取某个国家/地区的 ISO 代码首字母。
我有全名，但我想要 2 个字符的名字。

例如：
“United States”变成“US”，“Netherlands”变成“NL”。

我的代码是这样的：

$locations = array();

$args = array (
    'taxonomy' => 'location','hide_empty' => true,'orderby' => 'name','order' => 'ASC',);

$get_locations = get_terms($args);

foreach ($get_locations as $key => $location) {
    $jobs_array = array();
    $location_name = $location->name;
    
    // Get jobs
    $post_type = 'jobs';
    $posts_per_page = -1;
    $jobs_args = array(
        'post_type' => $post_type,'post_status' => 'publish','posts_per_page' => $posts_per_page,'location' => $location_slug,);
    
    $jobs = new WP_Query( $jobs_args );
    
    if($jobs->have_posts()) :
        while ( $jobs->have_posts() ): $jobs->the_post();
        // $jobs_array = $post;
        $jobs_array[] = $post->post_title;
        endwhile; wp_reset_postdata();
    endif;

    
    $locations[$location_slug] = $jobs_array;
}

结果：

如你所见，关键是全名。
我希望有人知道如何实现这一目标。谢谢！

这个问题也发布在 wordpress Stack Exchange 上，因为它使用了来自 wordpress 帖子的查询循环。

解决方法

如果我没有正确理解所有内容，您希望 ARRAY KEY 包含国家/地区 ISO 代码而不是全名，对吗？

我建议创建一个自定义类，其中包含一个包含国家名称和 ISO 代码的数组。像这样：

<?php

class CountryIsoCodes
{
    const COUNTRIES = [

];

    /**
     * @param string $countryName
     *
     * @return string
     */
    public function getIsoCodeByCountryName($countryName)
    {
        if (!isset(array_flip(self::COUNTRIES)[$countryName])) {
            trigger_error('Could not find country code ' . $countryName,E_USER_ERROR);
        }
    
        return array_flip(self::COUNTRIES)[$countryName];
    }
}

而不是在需要上课的地方调用它：

$countryCodes = new CountryIsoCodes();
$locations = array();

$args = array (
    'taxonomy' => 'location','hide_empty' => true,'orderby' => 'name','order' => 'ASC',);

$get_locations = get_terms($args);

foreach ($get_locations as $key => $location) {
    $jobs_array = array();
    $location_name = $location->name;

// Get jobs
$post_type = 'jobs';
$posts_per_page = -1;
$jobs_args = array(
    'post_type' => $post_type,'post_status' => 'publish','posts_per_page' => $posts_per_page,'location' => $location_slug,);

$jobs = new WP_Query( $jobs_args );

if($jobs->have_posts()) :
    while ( $jobs->have_posts() ): $jobs->the_post();
        // $jobs_array = $post;
        $jobs_array[] = $post->post_title;
    endwhile; wp_reset_postdata();
endif;


$locations[$countryCodes->getIsoCodeByCountryName($location_slug)] = $jobs_array;
}

希望有帮助。干杯

附言如果未找到国家/地区名称，我已向该类添加了一个错误触发器。您可以使用国家/地区来丰富 COUNTRIES 常量（如果缺少国家/地区，或者您正在使用不同的名称？

还请检查并修改国家/地区名称，因为它们可能与您存储在数据库中的国家名称略有不同...确保它们匹配;)
