Question

I am using php any mysql. I would like to create a timer that operates in the server side, and when time reaches a certain value (e.g. 06:00:00), it can trigger the running of another file (such as, update data of a table).

Actually, what kind of technique I shall use apart from php?

Thankyou…

Obviously if you can use them – cronjobs are the correct solution. But if you just have a little webspace or something where you cant setup cronjobs you need something else. You could of course just do it in php but this istn nice, as you have no guarantee that it runs at specified time, maybe it will much later.
The perfect solution to that scenario ist something like a webcron:
