连接数据库

一、全局配置定义

  1. return array(
  2.     'DB_TYPE' => 'mysql',
  3.     'DB_HOST' => '127.0.0.1',
  4.     'DB_NAME' => 'thinkcmf',
  5.     'DB_USER' => 'root',
  6.     'DB_PWD' => 'root',
  7.     'DB_PORT' => '3306',
  8.     'DB_PREFIX' => 'cmf_',
  9.     //密钥
  10.     "AUTHCODE" => '2oF6v4m67BdQnfwMSf',
  11.     //cookies
  12.     "COOKIE_PREFIX" => '03a9uH_',
  13. );

如果我们已经在配置文件中配置了额外的数据库连接信息，例如：

  1. return array(
  2.     //数据库1
  3.     'DB_TYPE' => 'mysql',
  4.     'DB_HOST' => '127.0.0.1',
  5.     'DB_NAME' => 'thinkcmf',
  6.     'DB_USER' => 'root',
  7.     'DB_PWD' => 'root',
  8.     'DB_PORT' => '3306',
  9.     'DB_PREFIX' => 'cmf_',
  10.     //密钥
  11.     "AUTHCODE" => '2oF6v4m67BdQnfwMSf',
  12.     //cookies
  13.     "COOKIE_PREFIX" => '03a9uH_',
  14.     //数据库2
  15.     'DB_CONFIG2' => array(
  16.         'db_type'  => 'mysql',
  17.         'db_user'  => 'root',
  18.         'db_pwd'   => 'root',
  19.         'db_host'  => '127.0.0.1',
  20.         'db_port'  => '3306',
  21.         'db_name'  => 'repast'
  22.        ),
  23.     );

二、实例化定义

  1. $User = M('User','cmf_','DB_CONFIG2');
  1.                                                                             作者：小夏
