CI配置多数据库访问的方法,ci数据库访问

本文实例讲述了CI配置多数据库访问的方法。分享给大家供大家参考,具体如下:

1、修改datebase.php文件,将:

$db['XXX']['pconnect'] = TRUE;

Copy after login

修改成:

$db['XXX']['pconnect'] = FALSE;

Copy after login

2、将原来的数据库链接定义复制一份,如当前

$db['bbs']['hostname'] = '你的数据库IP地址';
$db['bbs']['username'] = '链接用户名';
$db['bbs']['password'] = '数据库连接密码';
$db['bbs']['database'] = '数据库名';
$db['bbs']['dbdriver'] = 'mysql';
$db['bbs']['dbprefix'] = 'cg_';
$db['bbs']['pconnect'] = FALSE;
$db['bbs']['db_debug'] = TRUE;
$db['bbs']['cache_on'] = FALSE;
$db['bbs']['cachedir'] = '';
$db['bbs']['char_set'] = 'utf8';
$db['bbs']['dbcollat'] = 'utf8_general_ci';
$db['bbs']['swap_pre'] = '';
$db['bbs']['autoinit'] = TRUE;
$db['bbs']['stricton'] = FALSE;

Copy after login

其他的都不需要修改,然后在你的控制器里面加载 构造函数:

function __construct()
{
  parent::__construct();
  $this->XXX= $this->load->database('XXX', TRUE);
  //注意,这里的XXX代表上面的bbs,修改成bbs就行了
}
Copy after login

使用方式:

$query = $this->bbs->query($sql);
//和以前一样,就是这里用到了$this->XXX-> XXX就是你定义的bbs
$rs = $query->result();

Copy after login
