ThinkPHP的控制器

控制器  
跨模块调用

1、模型的命名  
2、实例化模型  
3、属性访问  
4、连接数据库  
5、创建数据  
6、连贯操作  
7、CURD操作

    		'server' => 'localhost',
    		'port' => '3306',

    		'database' => 'dada' 
    );
    
    
    $conn = @mysql_connect($db['server'].':'.$db['port'],$db['username'],$db['password']);
    if (! $conn) {
    	echo "服务器不能连！" . mysql_error();
    } else {
    	// 声明字符集
    	mysql_set_charset('utf8', $conn);
