摘自ecshop的一个删除商品记录的函数，比较完整的说，其中后台所调用的删除方式都已经有了，如实现的从回收站删除多个商品、取得有效商品ID、删除商品图片和轮播图片文件、删除商品、删除商品的货品记录、删除商品相册的图片文件、删除商品相册、删除相关表记录、删除相应虚拟商品记录、清除缓存，看起来好完整的说，在这里记录下来，待到二次开发的时候可以直接进行实例化应用，当然，如果这个函数不能够满足我们的需求，还可以在函数里面再添加相应的方法，夏日博客摘出来的完整函数代码如下:

/**

 * @param   mix     $goods_id   商品id列表：可以逗号格开，也可以是数组
 * @return  void
