The new deal will keep the 33-year-old at Craven Cottage until at least the end of next season.
“I’m delighted to have signed a contract extension this morning,” Murphy said on Saturday.
“As a club we’ve achieved great things during my time at Fulham so far, not least our highest ever League finish and reaching the Europa League Final.”
“It is a great source of pride for me, as club captain, to have played a role in some truly historic moments for Fulham Football Club.”
“On Sunday we’ve got a massive game against Spurs in the FA Cup and as a team we will give our all tomorrow afternoon to earn a place in the fifth round.”
“I’m sure it’s going to be a great atmosphere at the Cottage and hopefully we can continue our impressive start to 2011.”
