php - 当我加载到 CI 框架中的 Controller 时出现调用未定义函数模型()的错误

Question

我刚刚学习 codeigniter，这是我的

模型 second_con.php

class second_con extends CI_Model 
{  //CI version 3.0

public function second_mod() 
{

    $query = $this->db->query('SELECT * FROM subdepartment');

    if($query->num_rows() > 0) 
    {

        foreach($query->result() as $rows)
        {
             $datas[]  = $rows;
        }
        return $datas;
    }
   }
   }

Controller second.php

class second extends CI_Controller {  

public function index() {

    $this->load-model('second_con'); //line 7

    $this->load->view('home1');
}
}

在此之后，当我尝试查看此页面时。它显示错误如下。谁能找出我哪里出错了？

您在此处load-model缺少>

应该是

$this->load-model('second_con'); # wrong

改成这个

$this->load->model('second_con'); # correct
