I am very wonder how to run php script always or specific time WITHOUT connection or call of user/admin. For example, I am making a push-messaging alarm application. This app sends message to user when time is 5:00 PM. But push-message system requires php server page that requests FCM(push-message server) request.(This app is just example, so please don't answer me how to make push message.)
This is not the only situation I have to solve. If I have many advertisers who want to advertise on my website, and some of advertisers pay for limited-time advertise, I have to stop providing that AD after 5:00 PM.
What I want to ask is: How to run php code in background? (likely purpose to make time-alart push message) and run code in PARTICULAR TIME or ALL TIME?
