Do you have any unused variable, please?
By Ondrej Brejla on Sep 21, 2011
Today we would like to introduce you a very useful feature, which is well known by most of you. Do you know experimental hint which tried to check your unused variables? I hope you do. But almost noone used it. And why? Because it was slow, unstable and, unfortunately, it didn't work :/
But now we threw it away and we made a pretty new implementation. It is fast, stable and, fortunately, it works ;)
You can enable/disable that in Tools -> Options -> Editor -> Hints -> PHP -> Stable -> Variable does not seem to be used in its scope.
