让PHP在特定日期运行一次[关闭]

Question

I've looked into this, and I've found out about Cron jobs - but the thing is that it only has to run once ever.

Background: My users can create something that expires - and they choose when it expires.

One of my solutions: Maybe I don't have to expire it on that day - whenever someone requests that thing, then I can check whether or not it has already expired, and if it has, then I can change that thing accordingly.

Why it wouldn't work: I'd also like to send an email out when that thing expires.

Thanks for any help!

Answer 1

You could save a time-stamp together with the user item, that you call expire for example

then you could run a cron job that removes all items that has passed the expired time.

if($item.expire < time())
{
   // Item has expired, remove it
}
