php - PHP JSON：从 Yahoo JSON 响应联系人对象中读取联系人详细信息

Question

将 Yahoo Contact API 集成到我的网站后，我开始获取用户联系人列表作为 Yahoo JSON 响应联系人对象。

以下是响应格式：

{"contacts":{"start":0,"count":5,"total":110,"contact":[{"isConnection":false,"id":16777250,"fields":[{"id":16777292,"type":"yahooid","value":"ahmed_love7353","editedBy":"OWNER","categories":[]},{"id":16777291,"type":"name","value":{"givenName":"ahmed","middleName":"","familyName":"_love","prefix":"","suffix":"","givenNameSound":"","familyNameSound":""},"editedBy":"OWNER","categories":[]}]},{"isConnection":false,"id":52,"fields":[{"id":124,"type":"email","value":"15688708283341592078@mail.orkut.com","editedBy":"OWNER","categories":[]}]},{"isConnection":false,"id":16777271,"fields":[{"id":16777343,"type":"email","value":"abcdall4u@gmail.com","editedBy":"OWNER","categories":[]}]},{"isConnection":false,"id":31,"fields":[{"id":69,"type":"yahooid","value":"supriya_9392","editedBy":"OWNER","categories":[]},{"id":70,"type":"name","value":{"givenName":"Supriya","middleName":"","familyName":"Agarwal","prefix":"","suffix":"","givenNameSound":"","familyNameSound":""},"editedBy":"OWNER","categories":[]}]},{"isConnection":false,"id":23,"fields":[{"id":45,"type":"phone","value":"09470657255","editedBy":"OWNER","flags":["MOBILE"],"categories":[]},{"id":44,"type":"name","value":{"givenName":"akhilesh","middleName":"brother()","familyName":"","prefix":"","suffix":"","givenNameSound":"","familyNameSound":""},"editedBy":"OWNER","categories":[]}]}]}}

问题：

无法从上述代码中读取（获取）givenName、familyName 和电子邮件。

试过：

使用json_decode();过，但我再次无法阅读相同的内容。

以下是解码格式：

问题：

如何以简单的方式阅读 givenName、familyName 和 email？
使其更具可读性的最佳方法是什么？

注意：我是 JSON 新手。

试试这个：

<?php
$json = '{"contacts":{"start":0,"count":5,"total":110,"contact":[{"isConnection":false,"id":16777250,"fields":[{"id":16777292,"type":"yahooid","value":"ahmed_love7353","editedBy":"OWNER","categories":[]},{"id":16777291,"type":"name","value":{"givenName":"ahmed","middleName":"","familyName":"_love","prefix":"","suffix":"","givenNameSound":"","familyNameSound":""},"editedBy":"OWNER","categories":[]}]},{"isConnection":false,"id":52,"fields":[{"id":124,"type":"email","value":"15688708283341592078@mail.orkut.com","editedBy":"OWNER","categories":[]}]},{"isConnection":false,"id":16777271,"fields":[{"id":16777343,"type":"email","value":"abcdall4u@gmail.com","editedBy":"OWNER","categories":[]}]},{"isConnection":false,"id":31,"fields":[{"id":69,"type":"yahooid","value":"supriya_9392","editedBy":"OWNER","categories":[]},{"id":70,"type":"name","value":{"givenName":"Supriya","middleName":"","familyName":"Agarwal","prefix":"","suffix":"","givenNameSound":"","familyNameSound":""},"editedBy":"OWNER","categories":[]}]},{"isConnection":false,"id":23,"fields":[{"id":45,"type":"phone","value":"09470657255","editedBy":"OWNER","flags":["MOBILE"],"categories":[]},{"id":44,"type":"name","value":{"givenName":"akhilesh","middleName":"brother()","familyName":"","prefix":"","suffix":"","givenNameSound":"","familyNameSound":""},"editedBy":"OWNER","categories":[]}]}]}}';
$obj = json_decode($json);
foreach ($obj->contacts->contact as $contact) {
    if (isset($contact->fields[1]->value->givenName)) {
        echo $contact->fields[1]->value->givenName . '<br>';
    }

    if (isset($contact->fields[0]->type) && $contact->fields[0]->type == 'email') {
        echo $contact->fields[0]->value . '<br>';
    }
}
?>
