How to make a self-deleting link live in time?

Question

PHP

Hello!

Tell me how to make the link live for a specific time, from the moment of entry, and the time was fixed according to the time spent on it.

Answer 1

Since the MySQL tag is worth it, I assume that the links are stored in the database?
So for each link you need to make a column with the time the link was created and the time of the first click (visit) on it.
Link creation time can be used if it is necessary, in principle, to limit the link in time, regardless of whether it was visited or not.
Default entry time null. When opening a link, we look at this value, on the first visit we fill in the current date, on repeated clicks we compare the date and current time.
If more than a certain time has passed, we consider that the link has been deleted.
You can also actually delete links with an expired date from the database, while links where the visit date nullis considered not visited and are not deleted. It already depends on your requirements.

Answer 2

Create links on time? Probably not a link, but the provision of content in accordance with the lifespan?
If yes, then create a token and lifetime. When prompted, check the deadline. If the deadline has passed, then the error 404.
