php - 如何同时运行两个数组

Question

嗨， friend 们，如果我用 codeigniter 运行 php，我会收到以下错误:

A Database Error Occurred Error Number: 2014 Commands out of sync; you can't run this command now CALL get_sub_menu(3) Filename: C:\xampp\htdocs\ci\system\database\DB_driver.php Line Number: 330

Controller :

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class Learnersway extends CI_Controller
{
    function __construct()
    {
        parent::__construct();

        $this->load->model('home');
    }
    function index()
    {
         $data['main_menu'] = $this->home->select_main_menu();
         $data2['sub_menu'] = $this->home->select_sub_menu();
        $this->load->helper('url');
        $this->load->helper('html');
        $this->load->view('home',$data,$data2);

    }
}
?>

注意:

1. 如果我同时运行数组 $data 和 $data2。我遇到了以上错误。
2. 但我可以一次运行一个。

请告诉我如何同时运行数组 $data 和 $data2。

Answer 1

就用

$data['main_menu'] = $this->home->select_main_menu();
$data['sub_menu'] = $this->home->select_sub_menu();
....
 $this->load->view('home',$data);

你可以通过以下方式让他们看到

print_r($main_menu);
print_r($sub_menu);
