This is not yet an OOP thingie.  It is a simple programming thingie.  If you Want to use OOP, fine, but first put some code together to show us what you are having problems with.   That will answer the question whether it is your algorithm or you knowledge of using OO

How about a database table with a column called "logins".

Add 1 to the user each time there is a successful login.

Then, if logins == 3, create a warning message that indicates they've reached the limit.

(Heck, you can even use this to create a message at every visit to indicate how many visits are remaining for that user.)

I think you mean, add 1 when there is an UNsuccessful login.

...and then, the next step is to set the counter to zero if there's a successful logon. 

A less secure way would be to store the count as a cookie, but if you've got a tech savvy user they can just delete it and have infinite attempts.

OR make the login process an Ajax POST and do the counting with in-page javascript, though there's no long term storage for that beyond cookies.

DB is the best answer, frankly.
