friend system?

[eluser]xwero[/eluser]
two tables is all you need to start

persons : id, name, ...
friends : person_id, friend_of

You could put the friend_of field in the persons table, as long text field filled with a comma separate list, but then you would have to use sql statements like

Code:

select name from persons where friend_of like '%?%'

which aren't that fast as

Code:

select person_id from friends where friend_of=?

I hope this gets you started.
