在编写程序中，写添加和更新SQL语句是一个比较烦琐的过程，特别是在表结构比较复杂的时候 这个程序主要是根据数据表格式自动生成添加/更新的SQL语句，然后由 程序员 直接加入到程序中，方便编程 下面是文件，方法建立一个单独的文件，按照下面的说明建立相关
在编写程序中，写添加和更新SQL语句是一个比较烦琐的过程，特别是在表结构比较复杂的时候这个程序主要是根据数据表格式自动生成添加/更新的SQL语句，然后由程序员直接加入到程序中，方便编程
下面是文件，方法建立一个单独的文件，按照下面的说明建立相关文件，运行即可
index.php 索引文件
config.php 配置文件，转换get/post数据
addxxx.php 根据提交表格数据生成SQL语句
addxxx2.php 根据数据库表信息生成SQL语句，配置数据库在文件内部
