站长图库向大家介绍了mysql数据库,mysql数据字典生成等相关知识,希望对您有所帮助
这篇教程教大家做一个自动生成数据库数据字典HTML文件的代码，有时候在开发系统制作系统说明的时候很有用。不多说了，直接上代码：
mysql字典生成代码

php dict.php -h 127.0.0.1 -u root -p 123456 -P 3306 -d blog_service
参数说明
-h mysql服务器地址 -u mysql用户名 -p mysql密码 -P mysql端口 -d mysql数据库名
参数都有默认值，-d参数必传 最简单的用法：
php dict.php -d blog_service
执行命令后生成一个以数据库名命名的html文件
