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','pwd');
    define('DB_NAME','dbname');
    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 ' . DB_CHAR);
    $sql="SHOW TABLE STATUS FROM " . DB_NAME;
    $result=mysql_query($sql);
    $array=array();
    while($rows=mysql_fetch_assoc($result)){
    $array[]=$rows;
    }
    // table count
    $tab_count = count($array);
