Indeed! The "flat table model" is simple, efficient and - I think -
sufficient. Thanks!
I also found this article which explains the "fourth" method not reall
I did one once where the key to the table was a string, and the string
contained 1 to n Node Numbers separated by a separator character.
"1"
"1.1"
"1.1.1"
"1.2"
select data from table where node between (1 and 2)
resulted in an entire limb of the tree being retrieved. Limitations were
the size

Hi,
I wonder what you think are the best (or "least worst") strategies to
store and retrieve hierarchial data (such as a "threaded" discussion or
a multi-level menu tree) in MySQL using PHP?
I have been using table structures where each row contains a parent
reference, such as:

Flexibility, I would guess. With PHP's current behavior one can:

As far as I know, this is fairly common in most programming languages

force the child class to override what the parent class's default
