Unity通过Php访问MySql

1.上网下载一个PHPNOW，文件包非常小，但是功能却很强大（下载链接 http://pan.baidu.com/s/1bnpjwUN）。

2.安装PHPNOW,注意不要有中文路径，安装方法也很简单，解压后双击Init.cmd根据提示做就可以。

3.安装后可以在浏览器上输入：localhost/index.php，浏览器会打印出PHPNOW的相关配置信息。

4.安装Dreamweaver CS6,用于编写php代码。

5.使用phpMyAdmin登录数据库,在浏览器中输入localhost/phpMyAdmin

导入一个数据库：附件中有

添加一个用户：用户名和密码要与unity中的登录名和密码一致：wenjian  、1234

6.Unity代码编写
