  The fully relativistic multiconfiguration Dirac--Hartree--Fock method is used
to compute excitation energies and lifetimes for the 143 lowest states of the
$3s^23p^3$, $3s3p^4$, $3s^23p^23d$, $3s3p^33d$, $3p^5$, $3s^23p3d^2$
configurations in P-like ions from Cr X to Zn XVI. Multipole (E1, M1, E2, M2)
transition rates, line strengths, oscillator strengths, and branching fractions
among these states are also given. Valence-valence and core-valence electron
correlation effects are systematically accounted for using large basis function
expansions. Computed excitation energies are compared with the NIST ASD and
CHIANTI compiled values and previous calculations. The mean average absolute
difference, removing obvious outliers, between computed and observed energies
for the 41 lowest identified levels in Fe XII is only 0.057 \%, implying that
the computed energies are accurate enough to aid identification of new emission
lines from the sun and other astrophysical sources. The amount of energy and
transition data of high accuracy is significantly increased for several P-like
ions of astrophysics interest, where experimental data are still very scarce.
