First, is the 'headers', which are called 'headers' because they come at the head (beginning) of the data. Then comes a blank line, to signify the END of headers. Finally, the 'body' comes out, which is what you see when you do "View Source" -- It's the actual HTML. Headers include meta-information such as the type of Content (text/html or image/jpeg or image/gif or ...) In your case, test.php has something on line 9 that is sending out some HTML (or blank lines or ...) Once that happens, PHP has to dump out all the headers collected so far, and then a blank line, and then start your content. If you try to set a cookie *AFTER* that, when the headers are already gone, and the blank line has gone out to signify the end of headers, IT'S TOO LATE. You have to re-arrange your code to get the Cookies and any other headers to happen *FIRST* and then your HTML after that. You can cheat and turn on "output buffering," but that comes with its own performance penalties and issues. You'll probably have a cleaner, more clear, more easily maintained body of PHP code if you arrange your headers to come out first anyway. -- Like Music? http://l-i-e.com/artists.htm
