session_start();

[agmorgan]

I am following a teach yourself book on PHP..

The books program comes up with the following

session_start();

However, when up run it i get the following error message

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/cale63/public_html/gbler/Login.php:10) in /home/cale63/public_html/gler/Login.php on line 18

Can some one give me an explanation as to what I may be doing wrong..

[man]session_start/man has to be called BEFORE anything is output. That even means a white space, check your file to make sure that nothing is sent to the browser before it is used.
