今天偶尔兴趣，调试一下以前在Win下写的数据库封装类，结果出现Fatal error: Class 'option' not found的奇怪错误，很郁闷，前面是打印了一大片optin类的源代码，然后就是Xdebug的错误报告，这到底嘛子问题，以为是类声明的问题，然后用require_once加载了所有文件，还是不行
我的数据库类执行顺序是：mysql extends db; db extends option;调用方法是$db = db::getinstance('mysql'); $db -> Config($config); $db->find();
为什么在Win下可以，在Linux下不行，测试过，不是文件权限的问题，也不是文件命名的问题；用过直接加载，也用过__autoload;为什么会把option整个文件的代码都打印在网页上面？
实在没办法了
求解答！

会不会是<?php写成<?样了？
使用绝对路径的？
