你可以把代码写在首页的里面，每次有人访问网站都去检查一下是否有需要确定收货的订单，定时上下架就是这么做的
自动确认收货这个状态如果仅仅是让客户端看的话，等用户下一次上线的时间，做一次运算就可以了。
如果有其它用处的，建议分开用途。
每天定时半夜筛选第二天 可以自动确认收货的订单
然后第二天 每10分钟 执行一次确认收货 开销不会太大吧 时间也相对精确
送货人员确认已经送到，就确认收货。
客户没点确认收货，不代表就是自动确认收货的。
定义一个最后自动收货时间这么个东西，通过下单时间和这个时间进行操作。在此订单超时之后第一次出现在人们眼前(任意方式)的时候修改状态。
如果你想以PHP来实现，定时脚本应该是最佳选择，虽然性能和消耗上要稍微高一点，但是可靠性较高，与其他模块和页面也无耦合。
不过这块最佳的方式还是以守护程序的方式实现，这可能就需要其他编程语言程序的支持了，在守护程序中，可以建立队列等复杂的数据模型，并且能够与请求处理程序间相互通信，就能够解决定时脚本轮询中性能消耗和浪费的问题了。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
