Hello,
I'm writing a sophisticated e-commerce software suite in PHP. What I want to be able to do is have customers use my software but not have access to the source code of my PHP so they can't copy it etc... So, I figured I'd use the file_get_conten ts(); function to get the data I need from my software to display it on their custom store page. I created the following script to do it.
While doing this, I came across a big show stopper, $_SESSION variables. When I add an item to my shopping cart, it creates a session variable with the new order number. If I use the script above, of course the session variables will not get sent over because file_get_conten ts(); only gets HTML content, so the SESSION variables I imagine are only being created on my server side and not on the customers web site...
I was then thinking of just redirecting to my cart software on my server, but that negates the idea of having the customers clients log in themselves and have the feature of customers logging in to their store.
I'm extremely confused... How should I approach developing my software so it can't be stolen?? I put a lot of work into this.
Thanks!
