What is inaccurate about it? Maybe it is out of date now, but when I first read it about a decade ago, when I did a fair amount of PHP development, I had personally encountered most of the issues mentioned in there.

I've heard that PHP has improved a lot since then, but I don't see how you could really fix all the inconsistencies, global state, and "oddities" without a lot of breaking changes and really making it into a different language.
