Best way to read file

Hi all. I am using readfile() to read and print the entire content of a .txt file into a site, but need to use </p> tags to break down the lines. I intend to be able, as an Administrator, to edit these text files later. What is the best way to accomplish this? Should I keep using readfile() or should I use any ther better way of doing this?
