Phillips was also sentenced to two years of probation during a court appearance Wednesday near Corpus Christi, where he grew up. Phillips must abide by other conditions, such as completing a DWI education program.
The Philippines-born actor had traveled from his home in California for a speaking engagement in November when he was arrested on suspicion of drunken driving.
Police said an officer suspected the 56-year-old Phillips had been drinking when he stopped to ask the officer for directions.
He later apologized for his actions, saying "it will never happen again."
