This study bases attention on new similarity solution and new similarity reductions of Phi-four equation has been subjected to Lie’s group theoretic method of infinitesimal transformation (Transformation from nonlinear PDE to nonlinear ODE) .Also produce another new similarity reduction of that equation obtained by direct method. To the best of our knowledge, we are first to obtain a new similarity solution is expressed in terms of trigonometric function and new similarity reductions are successfully reported. Therefore we reported Intermediate integrals of reduced ordinary differential equation
