tp3.2中配置链接多个数据库

config.php

return array(
   //'配置项'=>'配置值'

   //缓存
   //'DATA_CACHE_TYPE' => 'Memcache', 
    //'MEMCACHE_HOST'   => 'tcp://192.168.0.227:11211',  
    //'DATA_CACHE_TIME' => '3600',

   'DEFAULT_CONTROLLER'    =>  'Index', // 默认控制器名称
   'DEFAULT_ACTION'        =>  'index', // 默认操作名称

   //数据库配置 beruiuser
   'DB_CONFIG1' => array(
      'db_type'  => 'mysql',
      'db_user'  => 'root',
      'db_pwd'   => 'aisijkl81',
      'db_host'  => '192.168.0.111',
      'db_port'  => '3306',
      'db_name'  => '2222',
   ),//里面存在跨库操作

   //数据库配置 br_esfmanager
   'DB_CONFIG2' => array(
      'db_type'  => 'mysql',
      'db_user'  => 'root',
      'db_pwd'   => 'aisijkl8*1',
      'db_host'  => '1111111',
      'db_port'  => '3306',
      'db_name'  => '444',
   ),//里面存在跨库操作

   'domain' => 'demo',//这里上线后应该为api

代码里使用

$data=M()->db(2,"DB_CONFIG2")->table("mn_r_house_web")->where($where)->find();
