Simple 20 Minute PHP Project

I have a very simple 20-minute PHP project that does the following. In the php files there is a list of text files available to edit in an include file - like [login to view URL] and that include file simply includes the path to the text file which should be editable so an example of that file is like. /path/to/[login to view URL] /path/to/[login to view URL] etc... When the main php is run it creates a drop down menu of the files listed: file1 file2 and when one is selected it looks for the part in the file that reads whitelist= and then has a array separated by space. For example whitelist=[login to view URL] funiz [login to view URL] sugarcookies [login to view URL] and it displays them in a text box one per line: [login to view URL] funiz [login to view URL] sugarcookies [login to view URL] Which allows the user to add or delete entries. SIMPLE AS CAN BE. When they are entered or deleted it saves the file, ignoring all other data in the file leaving it untouched but adds any added data or deletes any deleted data from the whitelist= line. All still [spacebar] separated. It could no be any more simple. Please bid accordingly and make a specific, non-generic bid and a time when exactly this will be complete. This is it, this is the entire program and a great chance to get some starting feedback and to work in the future with a top-rated buyer. Any questions, ask. No, I cannot give server details. I have attached an example file.
