Clean keys should return the whole arrays not one item :-)

Rob, you left out that "by reference" (BTW a trick that i didn't really knew/used before. Learning from your code :-) ) foreach( $arrays as &$blah){}

I think i'm gonna re-do all of this and have the aliases go into the sql query itself, which should perform better than changing the keys after the fact.

first pull, then destroy :-)
