如何在 CodeIgniter 中使用 MySQLi 驱动程序

如何在 PHP 原生查询中使用 mysqli 驱动程序?

How can I use mysqli drivers in PHP native query?

例如.我的代码:

型号

class Home_model extends CI_Model{
    public function getusers(){
        $q = "SELECT * FROM `users`";
        return $r = mysqli_query($q);
    }
}

控制器:

class Home extends CI_Controller{
    public function iterateuser(){
        while($row = mysqli_fetch_object($this->Home_model->getusers())) {
            echo $row->username;
        }
    }

我上面的代码有一个错误，说:

My code above has an error, saying:

mysqli_query 需要至少 2 个参数

mysqli_query expects at least 2 parameters

CodeIgniter 中是否有一种方法可以传递 mysqli_query() 第一个参数上的链接，如 php.net 文档中所述http://php.net/manual/en/mysqli.query.php

Is there a way in CodeIgniter to pass the link on the mysqli_query() first parameter as described on the php.net documentation http://php.net/manual/en/mysqli.query.php

推荐答案

转到:

yourproject/application/config/database.php

变化:

$db['default']['dbdriver'] = 'mysql';

与:

$db['default']['dbdriver'] = 'mysqli';
