如何使用php检查请求日？

Question

For example: x user booking ticket on monday and ticket status changing as book. After three days, ticket status will change as free(empty) automatically. How can I do this?

Answer 1

Try something like this (using strtotime ):

if ($ticket_timestamp < strtotime("-3 days")) {
  // ticket is expired
}

Answer 2

You will usually want to check this by date. If you don't care about the actual date but just need to compare, you can use the time() function. The day is time()/60/60/24 .

You can store the timestamp of the order in the database and then compare it with the current time.
