array_walk inside class method

Hi All, I want to use "array_walk" function inside a class method. But the problem is i want the second argument to array_walk ( function name ) be a another function of the same class. when i gave like that its telling Error : function not exist. class some() { function func1() { } function func2() { array_walk($array,"func1"); } } What is the syntax or way to do this.
