Re: [PHP] Warning: Cannot send session cookie
take the closing php tag from the end of the first line plus the openning
tag from the begining of the second line. that is sending a line feed to
the browser.

You can work around this with the ob_start() and ob_end_flush() functions, but normally you'd want to move the session_start() or session_register() calls up to the top of your script. See below: "Note: If you are using cookie-based sessions, you must call session_start() before anything is output to the browser." http://www.php.net/manual/en/function.session-start.php "Note: In PHP 4, you can use output buffering to get around this problem, with the overhead of all of your output to the browser being buffered in the server until you send it. You can do this by calling ob_start() and ob_end_flush() in your script, or setting the output_buffering configuration directive on in your php.ini or server configuration files." http://www.php.net/manual/en/function.header.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
