现在我尝试访问第一个密钥lat和lon密钥。为此，我将使用$new_resp=json_decode($response, true)仅返回字符串“数组”来转换它。如何获得第一个 lon 和 lat 值？

试试这个。

    $curlSession = curl_init();
    curl_setopt($curlSession, CURLOPT_URL, 'https://nominatim.openstreetmap.org/search?email=[e-mail]&format=json&q=Berlin');

    curl_setopt($curlSession, CURLOPT_BINARYTRANSFER, true);
    curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, true);
    
    $jsonData = json_decode(curl_exec($curlSession),true);

    print_r($jsonData[0]['lat']); //This prints your first lat
    print_r($jsonData[0]['lon']); //This prints your first lon
    //if you want lat & lon for every record then use foreach loop. 

    curl_close($curlSession);
