Session_start Problem!!

[obrienkev]

Hi all,
Please could you help me out here. When I put session_start() in my code I get the following when I test my page in a browser:

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at c:\program files\apache group\apache\htdocs\newsite\welcome.php:6) in c:\program files\apache group\apache\htdocs\newsite\welcome.php on line 195

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at c:\program files\apache group\apache\htdocs\newsite\welcome.php:6) in c:\program files\apache group\apache\htdocs\newsite\welcome.php on line 195

Please can you tell me why this happens. When I leave out session_start it works fine! Is there something I should change in my PHP.ini file?? Thanks very much in advance.
Kevin.

The session needs to be started before any html is posted to the page - thats all.

Check for spaces and any include files that are before the session_start()

my suggestion is to put session_start() in the FIRST line
