php - Codeigniter db 选择哪里作为数组

Question

我有这段代码需要用来从数据库中获取结果，我在使用 codeigniter。这是查询的样子，

        $this->db->select('*');
        $this->db->where('broadcast_id', $bid);
        $query = $this->db->get('ih_noticeboard');
        $result = $query->result();
        if($query->num_rows() < 1){
            $data = "no feed ";
        }else{
            $data = $result;
        }

where子句中的$bid就是从这段代码中得到的，

    $this->db->select('broadcast_id');
    $this->db->where('broadcast_subscribers', $id);
    $query = $this->db->get('ih_broadcastors    ');
    if($query->num_rows() < 1){
        $data = "user not subscribed to any broadcasting";
    }else{
        $ress = $query->result();
        foreach ($ress as $row){
            $bid = $row->broadcast_id;
        }`

现在 select 只使用一个 $bid，如何将 $bid 用作数组？

Answer 1

这很简单。只需使用 $this->db->where_in('broadcast_id', $bid);

相反，如果 $this->db->where('broadcast_id', $bid);
