申请了个网站空间（云动力的）做测试，把本地做好的文件上传到网站连不上，连接改了估计是不到位大家帮忙看看！

*******************************************************************************************

开始在本地测试很好一点问题也没，一上到网络空间就有问题想请教大家指点下，困扰几天了
连接网络有两个问题请教（我是学美术的，希望大家不要笑话我！）：
1、数据库我是从PHPadmin管理：http://111.229.239.249:999进入建立的，这样做完不知道数据库位置是不是对的？是不是要放到ftp目录下的databases里面，还是建好就不管了？
2、下面php代码里面连接数据库和unity3d代码中连接地址不知道对不对。帮忙看看各位高手！！
*******************************************************************************************

下面是我网站的基本情况
送的三级域名假设是：wsk94.ydlkfree1.tzhytl.com
ip ：111.229.239.249
假设
PHPadmin管理：http://111.229.239.249:999
数据库地址：111.229.239.249
数据库名称：sp_wsk94
数据库用户名：sp_wsk
数据库密码：123456

假设
网站ftp地址：111.229.239.249
用户名：haha
密码：123
网站目录结构

数据库结构

php代码如下，已经拷贝到ftp的wwwroot下了
