The 23-year-old has moved to Craven Cottage for an undisclosed fee.
Halliche told Fulham's official website: "I'm so happy that my transfer to Fulham has been finalised.
"For me, the Premier League is the best league in the world and to be able to play alongside some wonderful players and to be given an opportunity to compete against some fantastic teams for a team like Fulham is something that I've always dreamed of doing."
