Book excerpt: The authors present preliminary measurements of branching fractions of the b[yields] s[bar s]s penguin-dominated decays B[sup[+-]][yields][phi]K[sup[+-]] and B[sup 0][yields][phi]K[sup 0] in a sample of approximately 89 million B[bar B] pairs collected by the BABAR detector at the PEP-II asymmetric-energy B-meson Factor at SLAC. They determine[Beta](B[sup[+-]][yields][phi]K[sup[+-]])= (10.0[sub -0.8][sup+0.9](stat.)[+-] 0.5(syst.)) x 10[sup -6] and[Beta](B[sup 0][yields][phi]K[sup 0])= (7.6[sub -1.2][sup+1.3](stat.)[+-] 0.5(syst.)) x 10[sup -6]. Additionally, they measure the charge asymmetry[Alpha][sub CP](B[sup[+-]][yields][phi]K[sup[+-]])= 0.039[+-] 0.086(stat.)[+-] 0.011(syst.) and set an upper limit on the CKM- and color-suppressed decay B[sup[+-]][yields][phi][pi][sup[+-]], [Beta](B[sup[+-]][yields][phi][pi][sup[+-]])
