如何在单个数组中显示更多数量的数组结果？

Question

I have two tables: login and follow`.

• Table name: login
  Fields: id,email,username,imageurl

• Table name: follow
  Fields: id:user_id:follow_id

It's like a Twitter follower's concept. I want to get the details of myfollower name and also myfollower 's following person's name.

For that I have written the coding as like below.

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"}]';

    }
}

I get the output like this:

[{"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"}]

This output displays myfollower 's name and myfollower 's following person name, but the problem is it displays only one member of myfollower 's following person name.

However, I want to the output like this:

[{"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","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"}]

This code is invalid JSON variable. i can't solve this question for you. Please update your question.
