Re: [PHP] using integers as array keys From: Alex Rice (alex <email protected>)
Date: 07/07/00

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!

Alex
