Re: using integers as array keys

Carroll: Thanks for the example. I stand corrected. To the list: I apologize for the noise. I don't know how I got so completely confused and worked up about this issue. I must be a) thinking in Perl (@ vs %) and b) must have actually been using $myarray[] instead of $myarray[$id], thus seeing keys which I did not expect to be defined yet. I've actually been using PHP, on and off, for a couple of years, if you can believe it :-) Thanks for not flaming me all to hell!
