ci framework mysql database Solution

本文实例分析了CI框架出现mysql数据库连接资源无法释放的解决方法。分享给大家供大家参考,具体如下:

使用ci框架提供的类查询数据:

$this->load->database();
$query = $this->db->query($sql);

Copy after login

程序运行一段时间之后,报错,告知数据库too many connections

很明显MySQL数据库连接资源超过了 max_connections 设定值。立马在每个查询之后,添加资源释放脚本:

$this->db->close();

Copy after login
Copy after login

仍然无法释放资源,怎么办呢?查看手册之后,知道了,只要把pconnect设置为false就可以了,设置大致如下:

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

Copy after login

设置 过之后,无需调用

$this->db->close();

Copy after login
Copy after login

即可自动关闭连接。
