How do I verify Philips curve empirically for recent years?
Simple correlation is not a good approach to evaluate the Phillips curve, because you are mixing many periods together. To get a better grasp of what this relationship might have been in the past, use a graphical approach. 

I suggest you to do something like this:



So basically, you plot the points, but add a line that connects them temporally. This might give you a better idea of some dynamics. It is clear from that graph that a simple correlation cannot capture the complex dynamics of inflation and unemployment.

For example, this is an animation of the evolution of the Phillip curve for the US:



The author identifies three or four PC over 40 years, reflecting different political/economic periods. A simple correlation analysis however would show none.
