PHP Session not Saving

Question

I have this written at the very first line on every page of my website.

include(\"restd.php\");

and restd.php contains the following lines

Answer 1

Do you actually set $_SESSION['id'] on a page...

What you are trying to do here is:

1. Start a session and load the $_SESSION from the session handler
2. Check if $_SESSION contains key 'id'
3. Redirect to index.php if $_SESSION['id'] is not set

Do you actually do this in index.php?

session_start();
$_SESSION['id'] = something;
