PHP appointments control

[prometeus68]

I need to implement this function for my program.

It's about appointments and dates.

Client will get X appointments. 3,, 6, 9, ...any amount of dates.

It's like credit.... X=3 means 3 appointments.
Then, when 3rd appointment is reached , client can not get more appointments until client gets a new code with more "X" appointments.

Whats the path to follow ? Im new on PHP....

Thanx

If you are new in php it will be difficult for you.
First of all describe the form of setting the appointment count, who will be set that and where the user can found that setting.
What do you have now in your app?
What kind of app it is?
Who will attend for the appoinment (the client and who)?
What type of user do you have (admin, client, any else)?
