php ci框架 查询mysql 返回json数组

saszr

输入网站，
我要获得的效果是  [{"name":"aaa","id":"1","sex","man"},{"name":"bbb","id":"2","sex","woman"},{}...]
我现在的显示是  {"name":"aaa","id":"1","sex","man"}{"name":"bbb","id":"2","sex","woman"}{}...

这是我的代码：
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Demo extends CI_Controller {

    public function index() {
       $this->load->database();
       $query = $this->db->query('SELECT name, id, sex FROM user');

       foreach ($query->result() as $row){
       echo json_encode($row);
        }

    }
}


因为新手，看了一大圈，不是很明白怎么来实现，卡了好几天。

求指点。

不需要 foreach，直接 echo json_encode($query->result()); 试试
