This error occurs because you are logging in after you have submitted data to the browser.

When defining a session you are creating a cookie on the client machine with the session id via HTTP header, so if you have already sent data to the browser, the header has already been closed and sent, so you can not request the beginning of the session.

As a workaround, you can put session_start right at the beginning of your code, or set the session.auto_start directive in php.ini to true or in .htaccess if you are running an Apache server. This rule makes the session start automatically, without having to use session_start ()
