v9数据模型功能，允许用户把不同的数据表，分离到不同的数据库服务器上。以实现负载的分离，更加的符合大访问网站的需求。
数据分离方法1.数据库连接配置配置文件路径：caches\configs\database.php
- return array (
- 'default' => array (
- 'hostname' => 'localhost',
- 'database' => 'phpcmsv9',
- 'username' => 'admin',
- 'password' => 'admin',
- 'tablepre' => 'v9_',
- 'charset' => 'gbk',
- 'type' => 'mysql',
- 'debug' => true,
- 'pconnect' => 0,
- 'autoconnect' => 0
- ),
- /*可以根据自己需求设置多个数据库链接配置*/
- 'link1' => array (
- 'hostname' => 'localhost',
- 'database' => 'comment',
- 'username' => 'admin',
- 'password' => 'admin',
- 'tablepre' => 'v9_',
- 'charset' => 'gbk',
- 'type' => 'mysql',
- 'debug' => true,
- 'pconnect' => 0,
- 'autoconnect' => 0
- ),
- 'link2' => array (
- 'hostname' => 'localhost',
- 'database' => 'workflow',
- 'username' => 'admin',
- 'password' => 'admin',
- 'tablepre' => 'v9_',
- 'charset' => 'gbk',
- 'type' => 'mysql',
- 'debug' => true,
- 'pconnect' => 0,
- 'autoconnect' => 0
- ),
- );
2.数据模型配置
配置文件路径：phpcms\model中所有文件
该目录下所有*_model.class.php都是数据模型文件
例如：workflow_model.class.php
- defined('in_phpcms') or exit('no permission resources.');
- pc_base::load_sys_class('model', '', 0);
- class workflow_model extends model {
- public function __construct() {
- $this->db_config = pc_base::load_config('database');
- $this->db_setting = 'link2'; //可以通过修改db_setting设置该数据表所链接的数据库服务器
- $this->table_name = 'workflow';
- parent::__construct();
- }
- }
