PHP.

PHP is still the king at web, php5-cli might not be as popular as Python.

Python seems more popular at Academics, and it's essentially the Basics for the generic public, or replacing Java at colleges nowadays.

That been said, I use PHP myself, PHP7 looks promising.

Python 2 vs 3, AnguarJS 1 vs 2, the self-conflicted "upgrade" is double-sided.

PHP7 new features are very welcome and look great.

Speed improvement is great as well. Seeing 2-5x speed improvements. :)
