RE: [PHP] headers already sent and cookie problem

Thanks for your tips Mike! One nasty thing to debug is that the error only shows up from time to time. So now everything seems OK. What do i have now? I start my code with session_start Then include some files. The last one is get_cartID.php (remember?) Then i use several functions to have cart functionallity. In show_cart i include my page heading and then output further body and footer content. When I put the get_cartID include file AFTER include "heading.php" into my show cart function, the other functions start complaining they can't access the function get_cartID. Lots of text, sorry for that. But I still don't have the clue. Maybe you like to see my code? Any help welcome!

Take a good look at line 188 of store/cart.php to see what you can do so that it is not starting HTML output, or move the header calls above the point where it is included/required. > I know that the problem is the reading of the cookie and then > after some sripting outputting page HTML.

Actually, that should be a preventer for the problem, so long as the ob_start() is executed before output is started -- perhaps your ob_start() should occur earlier in your script? Cheers!
