The leading whitespace that Notepad inserts causes PHP to echo out that whitespace before any PHP processing has occurred. Basically this (note leading space): <?php Is the same as this: <?php echo(' '); Then, since the page output has already started, it's too late to perform any tasks that require HTTP headers such as setting cookies or establishing a session. Also, Notepad will not display this leading whitespace that it adds, so to see it you'll need to use a better text editor. For editing PHP files on Windows, I use Notepad++ (a popular open-source text editor for windows). http://notepad-plus.sourceforge.net/uk/site.htm On 2/6/07, Rob Church &lt;robchur(a)gmail.com&gt; wrote:
