数据|数据库|语句

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

自动生成添加表格，并产生相关sql添加语句，生成UPDATE语句（简单版）
