PHP-Script paid subscriptions to the site service [closed]

[moh301]

I search a script with follow features:[*]The user can pay the full functional website for some time (week, month, six months, a year - for example).[*]After payment, the script pass a parameter that the user has paid, and the user data insert into the database mySQL (name, start subscription date, the subscription end date).[*]Each time when user is authenticated on the site checking valid or not the subscription.[*]For some time before the end of the subscription script notifies the user via e-mail that the subscription ends (for example, a message comes once a day for a week before the end of the subscription).[*]If the user does not prolong their subscription, then script closes access to the site. If prolongs, then change the values in the database.Maybe there are already existing solutions?
