php生成数据字典

2016-10-17 liyangweb.com 李杨 PHP

开发中数据库必不可少,关于数据字典,独自开发的小项目还好 ,一旦项目大起来,或者其他开发人员参与进来,那么数据库就像是一本天书,尤其一些状态值,更是猜不透什么意思,这时候一个完善的状态字典就显得意义非凡了,而编写数据字典又是一件异常繁琐的事,尤其是数据库结构出现变动的时候。不过有了这个,生成数据字典将是一件非常享受的事情。

代码是网上找的,非原创,效果图如下:

代码如下:

<?php  
 /**

 $dbusername = "账号";  
 $dbpassword = "密码";  
 $database      = "数据库";  
 //其他配置  
 $title = '数据字典';

 mysql_query('SET NAMES utf8', $mysql_conn);  
 $table_result = mysql_query('show tables', $mysql_conn);

     $tables[]['TABLE_NAME'] = $row[0];  
 }

 foreach ($tables AS $k=>$v) {  
     $sql  = 'SELECT * FROM ';  
     $sql .= 'INFORMATION_SCHEMA.TABLES ';
