When I say efficiency, I mean in the economic sense. That the ratio of input it takes to develop some things in PHP is lower than it would be for other languages.
When I say exactly, I mean a precise, concrete example. I've used PHP for over a decade. I have yet to encounter a case where using it was optimal, only cases where using it was required by customer demands. That is why I am asking for a real example of something that is easier in PHP, instead of a vague "some stuff".
