you've got to start the session before you output anything to the browser. it's best to do it right after you set the <?php tag.

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\wamp\www\contacts\app.php:13) in C:\wamp\www\contacts\app.php on line 15

you get this error because something's already been sent to the browser. you've either echoed/printed something, or you included an external file that writes to the browser, like an html include.

you can use the $_SESSION variables anytime through the script, but you have to declare it right at the beginning.
