PHP Session vars disappear

When PHP Session vars disappear from one script to another

One reason might be that you tried to define a numeric session variable like $_SESSION[1]=100. This easily happens when you write $_SESSION[$x]=100 instead of $_SESSION[x]=100 (x would be 1 here). All session vars afterwards will still be available in the same script. But after the next session_start on the next site they will be gone.
