Codeigniter - Parse error: syntax error, unexpected '$this'

Question

我开始学习 codeigniter。我在尝试 运行 项目时遇到此错误。

Parse error: syntax error, unexpected '$this' (T_VARIABLE), expecting ';' or '{' in C:\xampp\htdocs\Codeigniter\application\models\post.php on line 5

我的模型-post.php:

class Post extends CI_Model{
    function get_posts($num=20, $start=0)
        $this->db->select()->from('posts')->where('active',1)->order_by('date_added','desc')->limit($start,$num);
        $query=$this->db->get();
        return $query->result_array();
    }
}

我的控制器-posts.php:

<?php
class Posts extends CI_Controller{
    function index(){
        $this->load->model('post');
        $data['posts'] = $this->post->get_posts();
        print_r($data['posts']);
    }
}

Answer 1

function get_posts($num=20, $start=0)

您缺少此函数中的大括号。应该是；

function get_posts($num=20, $start=0) {
