I am unable to understand when I execute etc.php, it give me the error "Warning: session_start(): Cannot send session cache limiter - headers already sent ....."

You need to have session_start() before _any_ output to the browser (such as HTML, spaces, newlines, etc). Sessions rely on cookies and the cookie must be set in the headers before any output. <?php any_php_code(); session_start(); any_other_php_code(); ?> <html> <body>...</body> </html> Also, this is better posted to php-general@lists.php.net since it has nothing to do with databases. -- ---John Holmes...
