Basically, Wordpress is written in PHP and this is the root of all evil.

Let's look at the roots of PHP: it was never designed as a programming language, it was a tiny script language used to create Rasmus Lerdorf's website. Thus, it has a lot of oddities like the === operaor.

Do you know why it it is there? Because they wrote a broken instr() wrapper and messed up the error handling. And instead of doing one thing right, they added another obfuscation layer. Great design.

Then, PHP was traditionally used by webdesigners, not programmers. This lead to tons of bad code and bad practices. It is not that you cannot write elegant code in PHP, but there is so much more bad code around that it is hard to find the good code.

So, why do wonder about this?
