Why do you think PHP is still worthy in this mobile ages? I haven't been convinced myself to choose PHP despite did Laravel for some websites and PHP7 isn't a reason for me as well.
PHP is just another tool. If we're talking about backend, then its perfomance is good enough for small to middle sized applications. PHP borrowed a lot of language features from other languages in the last decade, it's a different language now, still there is a lot of old poor written code.
PHP 7 is great for those who are already used PHP for years, cause it uses half of CPU resources doing the same tasks as PHP 5.6. I don't think there is any good reason switching from Golang for example if you are aiming for writing scalable applications; still, every experienced PHP dev I know are still getting their things done and doesn't consider switching.
True, but I'm concerning Wordpress are popular and Drupal 8 have revamped for the better or worst.
On the Node.js side, Coffeescript or Typescript write less code if confidence enough to be careful, won't it be better if PHP have a way to write less and more secure?

Looks interesting! I'm all in for writing secure code. Sadly, Zend said that they don't want PHP to change a lot because of backwards compatibility, and that's why we are still stuck with different bad ideas that appeared in its first versions...
PHP 7 will help to speed up Wordpress sites twice, but it doesn't help with code itself anyhow. I haven't looked at it for a long time, but back then its code was pretty bad. Drupal 8 built on top of Symfony 2 components is terrifying, as PHP's main selling point (and Drupal specifically) alwasy was simplicity.
Yeah, right thinking, I'm disappointed without Drupal 8 after waiting all these years. Wordpress could be where at PHP5.x native speed if they are on PHP7.
After that tweaking, I think you might be interested in SIMD for Javascript and hopefully, WebAssembly will make PHP even speedier performance.
