Ok, first off there are builtin functions to do this kind of thing: http://www.php.net/htmlspecialchars http://www.php.net/nl2br Secondly, think about what your code is doing, and the order that it's doing the replacements. The first thing you're doing is replacing the newlines with <br> tags. The second and third things you're doing will disable all the tags including the <br> tags you've just inserted, by replacing '<' with &lt; and '> with &gt html entities; The fourth thing you're doing is disabling the html entities by replacing '&' with &amp; including the entities you've just inserted as steps two and three. -robin
