They're not showstoppers, but there are a lot of them and it makes the language that much more annoying to use. They don't prevent me from using PHP, but they make it unpleasant. A lot of mental effort that could be going into making sure my own code makes sense has to go into making sure that PHP's behavior makes sense and matches my mental model, more so than with many other languages. It increases friction.
