把mysql数据库生成数据字典，直接可用便于查看数据库表、字段，做一个数据字典是很有必要的，下面只需要简单更改下配置就可以用了，样式也是挺好的。
<?php header('content-type:text/html;charset=utf-8'); define('DB_HOST','localhost'); define('DB_USER','root'); define('DB_PASS','root'); define('DB_NAME','test'); define('DB_PORT',3306); define('DB_CHAR','utf8'); define('APPNAME',''); $conn=mysql_connect(DB_HOST.':'.DB_PORT,DB_USER,DB_PASS); mysql_select_db(DB_NAME); mysql_query('set names ' .
