首先我们看下数据库安装表材料sucaihuo.sql和sucaihuo_data.sql

创建表结构sucaihuo.sql CREATE TABLE IF NOT EXISTS `meal_accounts` (

`id` int(5) NOT NULL AUTO_INCREMENT,

`name` varchar(20) NOT NULL,

`name2` varchar(30) NOT NULL,

`key` varchar(50) NOT NULL,

`secret` varchar(50) NOT NULL,

`code` varchar(30) NOT NULL,

`ord` int(6) NOT NULL,

`is_check` tinyint(1) NOT NULL,

`logo` varchar(100) DEFAULT NULL,

`cla` varchar(20) DEFAULT NULL,

PRIMARY KEY (`id`)

) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=4 ;

插入数据表sucaihuo_data.sql INSERT INTO `meal_accounts` (`id`, `name`, `name2`, `key`, `secret`, `code`, `ord`, `is_check`, `logo`, `cla`) VALUES

(1, 'qq', 'QQ登陆', '100433042', 'dd3134e26321bce95a446d659ef0020f', 'qq', 1, 0, 'Public/images/top_qq.png', 'login-type4'),

检查数据库配置 if ($_GET['testdbpwd']) {

创建表 //读取数据文件

读取配置文件，替换真实配置数据，并插入数据 //读取配置文件，并替换真实配置数据
