How can I make my PHP script run at a certain time everyday? [duplicate]

Answer 1

You can easily use your database to save the last execution of the script.

Each execution of a certain page you run a script that does the following :

• Check if more than 8 hours (example)

• Checks in the database if the script has already been executed

If executed: does nothing.

If not executed: starts and updates the date last execution in database.

Answer 2

There's a cli interpreter called php. Run your script through that as a cron job.
