2. How can I use the echo() function and then once it's displayed the text to save the file? To be more clear, I have a form. The user enters their username and comments. When they submit, they're brought to a page called comments.php, and they'll see their username and comments displayed on that page. I know how to do all that. What I'd like is for it to display their form info, and then save it to the file, so when someone else comes along, they'll see their info PLUS the first user's info.
I hope I was clear enough.
