Well at http://www.php.net/manual/en/session.examples.php there's a big fat Note at the top of the page which includes the following: "The keys in the $_SESSION associative array are subject to the same limitations as regular variable names in PHP, i.e. they cannot start with a number and must start with a letter or underscore.".

One word suffices here: register_globals! Or, if that doesn't suffice: if register_globals is turned on, all the $_SESSION entries are automatically registered as global variables -- so any numeric indexes will obviously be invalid and will "disappear". For consistency's sake, PHP enforces the restriction even with register_globals off. Cheers!
