    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

    <?php
$db = array (
		'server' => 'localhost',
		'port' => '3306',
		'username' => 'root',
		'password' => 'dada',
		'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', $conn);
	// 选择数据库
	mysql_select_db($db['database'], $conn);
}

    <?php
if (! isset ( $_SESSION )) {
	session_start ();
}
if (! isset ( $_SESSION ['userName'] )) {
	header ( "location:login.php" );
}

// 访问数据库，查询学生表指定学号的学生
