need this in PHP, css

I been asked to create a web application that will allow customers to upload files to the web server.

The web application must be able to do the following:

• Determine from a configuration file stored as a text file (created in a text editor) on the web server the following:
  • The name of the business.
  • The path of the folder where uploaded files are to be placed in.
  • Valid user names and password combinations.
• Prompt for a user name and password.
• Validate the user name and password.
• List files in the upload folder.
• Upload files to the upload folder.
• Delete files in the upload folder.
• Provide a logout option.

The web application should only prompt for a user name and password once. When the user has successful logged in, display the list of files already in the upload folder and allow for only logged in users to be able to upload and/or delete files..I also need the page to be styled
