Session Issue !

[121212]

Hello every1,
I've just started around with PHP, so please forgive my poorly knowledge ...
i'm making a login page, the other parts is ok, but when i try to write a session to recognize the user, i receive this error :

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /www/vndv.com/d/4/r/d4rk/htdocs/Login.php:3) in /www/vndv.com/d/4/r/d4rk/htdocs/Login.php on line 90

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /www/vndv.com/d/4/r/d4rk/htdocs/Login.php:3) in /www/vndv.com/d/4/r/d4rk/htdocs/Login.php on line 90

Thanks for reply !

Try searching these forums for the text of the error message (e.g, "Cannot send session cookie - headers already sent"). Short answer is that your page is producing output before you start the session. Long answer can be found by searching.

Check that the session data is at the top of the document as well.
