Hi, My company provides software solution to our clients, I have come across with one problem of how to control software licensing? For example, the client buys only 5 user license from me then how can I implelement this functionality in my php code that only five users can access to my web based application and the 6th user will not be able to access my application. Basically I need a method to implement software license control to enforce my licensing. If anyone knows the implementation of software licensing, please share. Thanks.
