}追问
我按你的方法写了，但是还是没有输出内容
追答那就是说明你根本没进入这个方法
你创建这个类了吗？
我是新手，还在学习中，所以不是很明白，我现在改了代码，你帮我看下对吗？能把数据库查的东西放入方法里面吗
追答类要先生成才能使用像这样
$goods=new Search_goods();
$goods_list=$goods->search_goods_list($bn,$price,$cost,$weight,$name,$cat_name,$store,$unit,$brand);
只有这样才是整个运行类里面方法的过程
不经过这样是不能运行类里的方法的
如果你是想做个判断，可以
if( isset($g_res['bn']) && $g_res['bn'] != '')
来做判断
问题在于在这个函数里面调用自己时参数个数完全不对，函数没有形参，调用时实参也驴头不对马嘴，这样都不报错？？
