I believe the behaviour of unset for array values changed between PHP
versions.
Check the ChangeLog to be sure.
Also, search PHP-Dev archives if you want all sorts of gory insider details
about why/when/who/what/where changed it, and maybe even a good argument, or
at least a couple flames, IIRC :-)
Meanwhile, you may want to consider upgrading if it's the older version not
behaving like you want...
I do think that in at least one version, you get NULL back if you ask for it
by key, but it won't show up in a foreach or each... But we're now getting
way too specific to trust my memory. I'm a big-picture guy.
