How can I track u

Answer 1

The simplest method would be cookie checking.

A better way would be to create an SQL database and assign the IP address as the primary key. Then whenever a user visits, you would insert that IP into the database.

1. Create a function included on all pages that checks for $_SESSION['logged'] which you can assign whatever 'flag' you want.
2. If $_SESSION['logged'] returns 'false' then insert their IP address into the MySQL database.
3. Set $_SESSION['logged'] to 'true' so you don't waste resources logging the IP multiple times.

Note: When creating the MySQL table, assign the IP address' field as the key.
