This site provides a nice overview, cool. It makes me wonder though, because IMHO PHP is adding too much new features that are often somewhat half-baked. What would be better is to have an actual specification to improve the core language. IIRC, Python gradually adds features where they are opt-in first (from __future__ import foo).

I'd gladly take a language which offers stability and gradual improvement over a language that just keeps adding new toys to play with. The software development cycle can take many years and from my experience, changes in the language or runtime are a burden.

But my biggest gripe isn't with PHP, it's that cheap web hosting still comes with PHP and MySQL. And I honestly can't blame them.
