Simple php page to display sharepoint files

I just need a single page maybe using some small db so i can link a sharepoint list of files into a select list. i want to click a button, login, and view my files in a list. thats it. i want ot be able to unlink or logout the account and have someone else login into their sharepoint and get their files. So not just my sharepoint account. you should know how to implement the sharepoint api and create a php page with a simple connection a mysql db. thats all im asking for. please dont give me fake bids, or ask me what my budget is. its clearly there what the range is. we can use my server to host this page. 1. click a button 2. login into sharepoint and store the information to remain logged in 3. display list of files 4. log out 5. login with new credentials to view files. files list should be saved per new userid.
