将关联数组中的一项添加到数组的每个关联数组答案

【问题标题】：Add an item from an associative array to each associative array of an array将关联数组中的一项添加到数组的每个关联数组

【问题描述】：

我正在尝试合并来自 2 个 API 调用的数据。第一次调用获得了我需要的大部分数据，第二次调用使用第一次调用中的 item(bill_id) 作为参数，以便为第二次 API 调用获取数据。我只需要第二次调用中的一项，因此我尝试将其添加到第一个数组中，然后将该数组作为 json 传递给客户端。

这是 webmethod 控制器..

    //AJAX calls
    function getUpcomingBills ($params = null) {
        $upcomingBills = $this->CongressAPI->get('upcoming_bills', $params);
        $upcomingBills = json_decode($upcomingBills, true);


        foreach($upcomingBills as $bill) {
            $p = ['bill_id' => $bill['bill_id']];
            $title = $this->CongressAPI->get('bills', $p);

            $bill['title'] = $title[17];
        }

        echo json_encode($upcomingBills);
    }

还有模特……

    public function get($method = null, $params = null) {

        $key = "...";
        $url = "http://congress.api.sunlightfoundation.com/";
        $params['apikey'] = $key;

        $ret = $this->curl->simple_get($url.$method, $params);

        if (!empty($ret)) {
            $ret = json_decode($ret, true);
            $ret = json_encode($ret["results"]);                
        } else {
            $ret = '';
        }

        return $ret;
    }

这将返回一个没有错误的 JSON 对象，但它没有将“标题”附加到第一个对象。

另外，当我尝试使用第二次调用的关联数组的标题（而不是 $title[17]）时，我得到了错误：

消息：非法字符串偏移 'short_title'

第二次 API 调用返回以下内容：（尝试获取 'short_title'）

感谢 GreeKatrina 的参考，我通过将我的方法更改为以下方法使其正常工作。

function getUpcomingBills ($params = null) {
            $upcomingBills = $this->CongressAPI->get('upcoming_bills', $params);
            $upcomingBills = json_decode($upcomingBills, true);


            foreach($upcomingBills as $bill => $val) {
                $p = ['bill_id' => $upcomingBills[$bill]['bill_id']];
                $title = json_decode($this->CongressAPI->get('bills', $p), true);
                $upcomingBills[$bill]['title'] = $title;
            }

            echo json_encode($upcomingBills);
        }

它现在传递对象中的 who json 数组
