php - 如何将具有键值对的对象转换为对象数组

Question

在 php 中，我得到的响应如下所示:

{
    "GB": "United Kingdom",
    "US": "United States"
}

我需要一些我可以像这样使用 map 循环的东西

   [
    { code: "GB", name: "United Kingdom" },
    { code: "US", name: "United States" },
   ]

但我想使用 PHP 将其转换为对象数组。可以使用 PHP 还是仅使用 Javascript 来完成？

function get_billing_countries( $request ) {
 
    $woo_countries = new WC_Countries();
    $countries = $woo_countries->get_allowed_countries();
    
    return $countries;
    
}

Answer 1

这可以在 php 或 Js 中完成，如果您想在传递给客户端之前在 php 中执行此操作

function get_billing_countries( $request ) {
 
    $woo_countries = new WC_Countries();
    $countries = $woo_countries->get_allowed_countries();
    
    $arrayCountries = [];
    foreach($countries as $key=>$val){
        $arrayCountries[] = ["code" => $key, "name" => $val];
    }
    return json_encode($arrayCountries);
    
}

在客户端Js中也可以采用类似的方式

如果在Js中响应如下

const responseCountries = {
    "GB": "United Kingdom",
    "US": "United States"
}
const countries = []
for(const property in responseCountries){
   countries.push({code: property, name: responseCountries[property]})
}
