php 读取表结构自动生成php类-php教程-PHP中文网

平时写项目的时候经常会碰到操作数据库，每次操作数据库的时候最麻烦的就是要写一个表映射的类，根据规律总结写了一个自动生成的小demo：

<code><span><?php</span><span>// 数据库配置参数</span><span>$db_config</span> = <span>array</span>(

    <span>'password'</span> => <span>''</span>,
    <span>'dbname'</span> => <span>'joe_db'</span>,
    <span>'charset'</span> => <span>'utf8'</span>
);
