do they need to be declared somehow? integrate time into the script or takes it from the server?

I... I don't understand what it is you're trying to do.
A variable in PHP is only going to exist for as long as the script is running.
E.G.
When you call that script $var will only be set to "foobar" until the script finishes. You can't then change the value of it somewhere and it will be a different value.
Even when building plugins in things like Wordpress there is still a script lifecycle. It sounds like you want to be reading something in from your filesystem at midnight every day, or want a script to react differently if it's run on two different days.
Either way, I think your approach is probably wrong.
Will run your script once a day at midnight, which might be exactly what you're after.

That still doesn't answer the question. Where is that variable getting stored? Is it in a database?

You are looking for a storage for your variable. Php variables will only exist for the session at max. Store the variable in a db table/inside a file. Then, have it resetted with a php script that is ran by a cron job at midnight, everyday.
Edit: example
Store n retrieve variables in file
Run cronjob every midnight

You want to keep that information stored in the DB along with a date. Just check the most recent row in the DB for the user, and then if the dates are different, insert a new row (e.g. start from 0). Otherwise update the existing row for the current day.
