This error message is because you are trying to send header information after you already printed some text. The header information have to come before any other information sent to the browser meaning : <?php Print ("hello"); header('Location: http://www.example.com/'); ?> WON'T WORK!!! But <?php header('Location: http://www.example.com/'); print ("hello"); ?> Will work And another ting the <?php should be in the first line of the php file even an empty line will generate the error!. Line 1=> Line 2=><?php Line 3=> header('Location: http://www.example.com/'); . . . WON'T WORK!! And you can use headers_sent() to check if you can send the header information if (!headers_sent()) { header('Location: http://www.example.com/'); exit; } Have a nice day Yaron Khazai -----Original Message----- From: sukalyan banga [mailto:sukalyanb@xxxxxxxxxxxxxx] Sent: Sunday, April 17, 2005 8:46 AM To: php-general@xxxxxxxxxxxxx Subject: chat script Sir, I am hosted a chat script at www.bioraj.net/raj/chat/ but it shows some error what should I do. sukalyan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
