it depends. the script i gave has you just place it on the page. playing a little you could probably make each into an small php file and access each with an "include" then create a folder and add each in it, a php with txt will be very small so you wouldn't need a ton of space.
Creating a form could work and it can function to store each on submission to your Database but this route is a lot more technical, you would have to create the DB tables, the script to send and receive the information, and keep it condensed ... this is not my area and I wouldn't be able to assist.
But I am sure it is possible... honestly I think it would be easy enough to just save them as individual php files and run with it. ...<this route.. you would need less script and a simpler to edit in my opinion.
