RE: php discussion online
couple of things...I would use $_POST rather than $HTTP_POST_VARS. Also, I would do an if(isset($_POST)). This is a small program, but preserving memory anywhere you can is a good thing..I would do this:
echo "<br>".(htmlspecialchars($name))."<br>".$subject."<br>".(nl2br($message)); and get rid of the: $new_name=htmlspecialchars($name); $new_message=nl2br($message); unless you plan on using $new_name and $new_message again in the script. As it is, you are defingin two new variables (and using memory), when you don't really need to.
