Display Problemo

I have a small php app that I'm building to display, insert, edit, etc... various types of code snipits (asp, php, html, etc...) in a db. I also have a download option that creates a text file with the code that they've selected. I have 2 problems...the first is that when I go to view the text file I have all sorts of <BR> tags within the text, this is due to the nl2br function I used prior to the db insertion. How would I get rid of those? The seond problem is when a user goes to view an html code example on the webpage, say with a hyperlink, the hyperlink is made active replacing the code with the actual <a href> tag. Thx in advance, Lerp
