挑战最棒的留言本的源码（四）

config.php文件

// 你的用户名和密码,以及数据库名,和表名,在这里一次定义!!!
// 由于怕用户名和密码被别人通过浏览器看到,所以用了php的扩展名,这样通过浏览就看不到了!!!.

$password='your_password'; //密码

$hostname='localhost'; //主机名,一般都为localhost

$db_name='your_db_name'; //数据库名
$table_name='your_liuyan_table'; //存放留言的表名

$table_name_cOntrol='your_control_table'; //控制表名

$number_records_to_display=5; //每页显示的留言条数!


$hang_zifu_number=50; //换行的一行字符数!



// 连接数据库,在这里连好!!!
