php - Remove Mysql row after specified time

I'm trying to create a computer reservation system, where user chooses a computer and select the time how long he will be using this PC. In that time other persons can't reserve this pc, I need to find a solution, how to automaticaly delete all rows containing reserved pc's after their time expires. Thank you for the advice.

The common way to handle this is to store an expires_at timestamp on the reservation row. Then your query to find any "open" reservations would have WHERE 'expires_at' < NOW() or something similar.
