Question

我搞砸了使用JSON的GND API，这似乎使提取特定数据变得更加困难（至少对我而言）。

我尝试从GND网站获取单个值。我已经有代码可以接收整个数据条目。

<?php

            // Setting the HTTP Request Headers
                $User_Agent = 'Mozilla/5.0 (Windows NT 6.1; rv:60.0) Gecko/20100101 Firefox/60.0';

                $request_headers = array();
                $request_headers[] = 'Accept: application/json';
            $request_headers[] = 'Content-Length: ' . strlen($data_string);


            //PHP Infos anzeigen lassen
            //phpinfo();

        $id = $_POST["id"];             
                // URL to fetch
                $url = "http://hub.culturegraph.org/entityfacts/$id";
                $curl = curl_init($url);
                curl_setopt($curl, CURLOPT_URL, $url);
                curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
                curl_setopt($curl, CURLOPT_HEADER, false);
                $json = curl_exec($curl);

                $status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
                curl_close($curl);


                // Performing the HTTP request
                //  Initiate curl
              $ch = curl_init($url);
              // Set the url
                curl_setopt($curl, CURLOPT_URL, $url);
                // Will return the response, if false it print the response
                curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
                curl_setopt($curl, CURLOPT_HEADER, false);
                curl_setopt($ch, CURLOPT_HTTPHEADER, $request_headers);
                curl_setopt($curl, CURLOPT_POST, true);
                curl_setopt($curl, CURLOPT_POSTFIELDS, $content);
                curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
                // Execute
                $result = curl_exec($ch); // Performs the Request, with specified curl_setopt() options (if any).
                // Closing
        curl_close($ch);    

        curl_error
?>

但是我只想从数据条目中获取特定的值，例如“ @type“ person”variantName。Json-Code的一部分如下所示：

@context    "http://hub.culturegraph.org/entityfacts/context/v1/entityfacts.jsonld"
@id "http://d-nb.info/gnd/118640445"

44  "Leonardo, da Vinci, Peintre, Naturaliste, Architecte"
45  "Leonardo DaVinci"

我该怎么做？
