如何在單個數組中顯示更多數量的數組結果？

Question

我有兩個表：login and follow`。

• 表名： login
  欄位： id,email,username,imageurl

• 表名： follow
  欄位： id:user_id:follow_id

這就像Twitter追隨者的概念。 我想獲取myfollower名稱的詳細信息，以及myfollower的跟隨者的姓名。

為此，我編寫了如下代碼。

public function follw ()
{
    if( $this->input->get("userid")  )

     {          

    extract($this->input->get()); 

    $followers_list = array();

    $follower = array();

    $query = $this->db->query('select follow_id from follow where user_id = '.$userid.'')->result();

    foreach($query as $row)

    { 
        $follower['follower_id'] = $row->follow_id;

        if($follower['follower_id'] == "")
        {
            echo "hi";
        }

        else
            {
        $query3 = $this->db->query('select username from login where id = '.$follower['follower_id'].'')->result();

        foreach($query3 as $row3)

            {
                $follower['followuser'] = $row3->username;
            }

        $query1 = $this->db->query('select follow_id from follow where user_id = '.$follower['follower_id'].'')->result();

        foreach($query1 as $row1)

            {
                $follower['follow_id'] = $row1->follow_id;

            if($follower['follow_id'] == "")

            {
                echo "jeeva";
                }


            else
            {
        $query2 = $this->db->query('select username from login where id = '.$follower['follow_id'].'')->result();

        foreach($query2 as $row2)

            {
                $follower['username'] = $row2->username;


            }

            }//second for each in else loop
            }//first foreach in else loop

            }//main else
        $followers_list[] = $follower;

        }

        $str = json_encode($followers_list);
    echo stripslashes($str);
}

else
{
    echo '[{"status":"Failure  - Error Occured - Not Enough Details provided"}]';

    }
}

我得到這樣的輸出：

[{"follower_id":"12","followuser":"janmejoy","follow_id":"24","username":"sarvana"},{"follower_id":"10","followuser":"jeeva","follow_id":"23","username":"selva"},{"follower_id":"6","followuser":"raj","follow_id":"17","username":"jeeva"},{"follower_id":"23","followuser":"selva","follow_id":"22","username":"guru"}]

此輸出顯示myfollower的名稱和myfollower的跟隨人的名字，但是問題在於它僅顯示myfollower的跟隨人的名字的一個成員。

但是，我想要這樣的輸出：

[{"follower_id":"12","followuser":"janmejoy",{"follow_id":"24","username":"sarvana",follow_id":"13","username":"jai",follow_id":"9","username":"raj"}},{"follower_id":"10","followuser":"jeeva","follow_id":"23","username":"selva"},{"follower_id":"6","followuser":"raj","follow_id":"17","username":"jeeva"},{"follower_id":"23","followuser":"selva","follow_id":"22","username":"guru"}]

Answer 1

[{“ follower_id”：“ 12”，“ followuser”：“ janmejoy”，{“ follow_id”：“ 24”，“用戶名”：“ sarvana”，follow_id“：” 13“，”用戶名“：” jai“， follow_id“：” 9“，”用戶名“：” raj“}}，{” follower_id“：” 10“，” followuser“：” jeeva“，” follow_id“：” 23“，”用戶名“：” selva“} ，{“ follower_id”：“ 6”，“ followuser”：“ raj”，“ follow_id”：“ 17”，“用戶名”：“ jeeva”}，{“ follower_id”：“ 23”，“ followuser”：“ selva “，” follow_id“：” 22“，”用戶名“：”專家“}]

此代碼是無效的JSON變量。 我不能為你解決這個問題。 請更新您的問題。
