Answer 1

write a record in your database for visitor which contain, the date they're visited and their ip (https://stackoverflow.com/questions/3003145/how-to-get-the-client-ip-address-in-php )

now you can check if the visitor was visited before in that day, by looking at your database

to get how much visitor just count the record
