Php 是否可以在foreach in codeigniter中使用foreach

这是我的函数-我得到一个错误

在变量

$data['stars']

中，我得到的最大星星数无效

我想从数据库中得到正确的星号，因为实际上星号表是不同的，所以这就是为什么

是否有可能从这个foreach中的另一个表中获取星星以获得准确的值

public function dbmovies()
{
    $this->db->order_by("videos_id", "desc");
    $this->db->where(array('publication' => 1, 'is_tvseries' => 0));
    $query = $this->db->get('videos');

    //get stars
    foreach ($query->result() as $key => $value) {
        $this->db->where_in('star_id', $value->stars);

        $queryStars = $this->db->get('star');
            $stars=array();

        foreach ($queryStars->result() as $star) {
            $stars[] = $star->star_name;
            $starone = implode(", ", $stars);

        }

        $data['videoId'] = $value->videos_id;
        $data['imdbid'] = $value->imdbid;
        $data['title'] = $value->title;
        $data['description'] = $value->description;
        $data['duration'] = $value->runtime;
        $data['views'] = $value->total_view;
        $data['stars'] = $starone;

        $alldata[] = $data;
    }

    $get['data'] = $alldata;
    echo json_encode($get, JSON_PRETTY_PRINT);
}

我得到的输出是这样的

有人能帮我吗？

在foreach$stars=array（）之前添加空数组；

           $stars=array();
        foreach ($queryStars->result() as $star) {
            $stars[] = $star->star_name;
            $starone = implode(", ", $stars);
        }

您必须将

$starone

变量移动到

foreach

循环的外部，以便它不会在循环内部被覆盖：

foreach（$queryStars->result（）作为$star）{
$stars[]=$star->star\u名称；
}
$starone=内爆（“，”，$stars）；

您可以使用join Query进行此操作！无论如何，我更新了您的问题，试试看！！虽然有效，但我只得到了一颗星，而且每个视频几乎至少有两颗星。实际上，它包含类似于“156720620972098”的星号这和我们从db检查id并获取星号请分享更多详细信息-您问题的标题不反映您提供的代码
