如何使用mamp连接数据库与codeigniter

Question

我想连接我的数据库在mamp服务器中的代码点火器。 这里是我的配置文件

$active_group = 'default'; 
$active_record = TRUE; 

$db['default']['hostname'] = 'localhost:3306'; 
$db['default']['username'] = 'root'; 
$db['default']['password'] = ''; 
$db['default']['database'] = 'lalcoresidency'; 
$db['default']['dbdriver'] = 'mysqli'; 
$db['default']['dbprefix'] = ''; 
$db['default']['pconnect'] = TRUE; 
$db['default']['db_debug'] = TRUE; 
$db['default']['cache_on'] = FALSE; 
$db['default']['cachedir'] = ''; 
$db['default']['char_set'] = 'utf8'; 
$db['default']['dbcollat'] = 'utf8_general_ci'; 
$db['default']['swap_pre'] = ''; 
$db['default']['autoinit'] = TRUE; 
$db['default']['stricton'] = FALSE; 

我把本地主机：3306，因为在数据库MAMP服务器端口号给出3306。

这里是我的控制器

class Testimonials extends CI_Controller{ 

    public function __construct() { 
     parent::__construct(); 
     $this->load->library('database'); 
    } 

    public function index(){ 
     $data=array(); 
     $this->load->model('testimonial_model'); 
     $this->load->database(); 
     $data['result']=$this->testimonial_model->get_testimonial(); 
     $this->load->view('testimonials_view',$data); 
    } 
} 

这里是我的模型

class Testimonial_model extends CI_Model{ 
    function get_testimonial(){ 
     $this->db->select('*'); 
     $this->db->from('testimonial'); 
     $this->db->order_by("r_id", "desc"); 

     $query=$this->db->get(); 
     return $result=$query->result(); 
    } 
} 

当我运行此代码，然后它显示下面的错误

A Database Error Occurred 

Unable to connect to your database server using the provided settings. 

Filename: C:\MAMP\htdocs\lalcoresidency\system\database\DB_driver.php 

Line Number: 125 

请帮我找到解决方案

Answer 1

$db['default']['db_debug'] = FALSE; 

而不是

$db['default']['db_debug'] = TRUE;
