If you meant to type "Phineas" as in the cartoon show "Phineas and Ferb", he is voiced by Vincent Martella.
If you mean Isabella, then the voice of Isabella is Alyson Stoner.
yes, yes they are. ;) yea, they're friends, but they're stepbrothers too. Linda (Phineas' mom) married Laurence (Ferb's dad) so now they are stepbrothers.
Bobby Gaylor voices Buford. He was one of the writers on Phineas and Ferb first season and he was the visual inspiration for the character Bobby Fabulous in the Love Handel episode. He also voices "Stanky Dog" in the Beach episode.
