Couple reasons:

* It's waning in popularity, new programmers aren't being taught and there isn't a lot of incentive for them to seek it out * Other languages are also good at making websites but many are more popular and more flexible - machine learning, video games, front-end web development, enterprise services (and sure PHP can be "enterprise" but many new cloud/apache projects are java first)

So yeah, I'm not saying PHP is dead...just that it's not a good investment for new developers and it's questionable for new projects.
