No. Fact is, the language is used by a lot of people who have no clue what they're doing. This article is not for them. Come to think of it, it's not for you either. It's for people who use PHP with some degree of competence.

I think PHP is to a large degree a victim of its own success. The runtime's ubiquity means that a lot of very incompetent people are fiddling around with things they don't understand. If you look at, say, PHP-related questions on Stack Overflow, you'll notice they are of extremely low quality that have nothing to do with PHP itself, but have everything to do with the person behind them not understanding the simplest things about programming.
