Sorting scanned documents

Hi folks, I have a project at hand and I don't really know how to go about it. The goal is to come up with a design that can search through and retrieve some scanned documents. I'm to scan those sheets and keep them in different folders, then design an interface that can search through the folder names, retrieves it, then displays the folder to the user! I was thinking PHP can do it. Please kindly help to come up with a better design, i'll be presenting it pretty soon. You might refer me to a forum that can help. Thanks in advance!

Pencil and paper. Write down how you are scanning the documents, how you are labelling them at the time, how you are storing them, etc.

Scanning is poor computing in the first place. You are recording something and not processing any data nor analysing it.
Have you considered a database? That may be a good way to store documents.
