Hi All!

Well first I would like to warn you that serialize/unserialize
functions are buggy with some php4 releases. This is the case
till 4.0.6 (as far as I remember) with objects but it's also
the case with complex arrays (I mean associative ones) at least
with one of the php release I can't remember the number. Check
the official php bug tracker to find it.

This scheme sounds right to me.

IMHO TEXT type is required, even if a varchar sounds enough at this
time: using TEXT will allow us to add as much settings as we want
later without having to change the table structure.

I also agree with sessions but we must be warn that it'll be a
hard work to take into account each possible php configuration.

I agree, it's a "very poor substituate" BUT I can't imagine an
other way to do it. We already have widely debated about the "SHOW
GRANTS" limits in one hand, we can't rely neither on the "SHOW
DATABASE" query neither on the "mysql_db_list" function on the
other hand (since lots of shared server disable this features for
security and server charge reasons).
That's a real and annoying problem...
