Read over some of the examples at:
http://us4.php.net/types.array
If you don't set a key, PHP starts with '0' and increments as you add
more elements to the array.
If you have "NOTICEs" turned on, I believe you'll get a notice saying
that $arrlevels[99] doesn't exist. It's not a fatal error, so PHP just
passes over it and doesn't say anything unless you tell it to.
# One dimensional array
$arrlevels = array(1,2,3);
# Three dimensional array. $lvl_guest is a key and 'levelname' is a key
$arrlevels[$lvl_guest]['levelname'];
