Replacing newlines (\n) with smething else

Hi, I'm trying to replace newlines with something else. For this example I'll use <br> as the thing to replace a newline with. This is what I tried and it doesn't work. $article = str_replace("\n", "<br>", $article); What am I doing wrong? $article is the string to replace the newlines in. I tried this with a period and that works as expected. Can I not replace newlines this way? Thanks, Jason Giangrande
