uhm, forgive me for being stupid, but why not? I was trying to use
numeric keys to store the id of db records that didn't start at 0.
using array_merge_recursive destroyed this information, so I have
to store it in the array itself, which in turn means I can't do stuff
like "if ($records[$id]['someval'])", or ksort on $records, or do
"foreach ($records as $id => $values)" and other nice things like
that after I've used array_merge_recursive.
and do you think, perhaps, it might be worth noting this in the man
pages?

peter lowe.
