Even with PHP7, PHP still feels like it is playing catch up. There is nothing new or revolutionary in PHP7, just adopting features present in other major languages. Adopting as other newer languages like Go and Rust seems to be moving beyond those features. A catch up into a world that's on its way out, if one will feel so blunt. PHP's raison d'être remains its ease of getting an instance running on a webserver. But…
Wait, Go hasn’t had any revolutionary change since it arrived 10 years ago. It is still basically the same language/package. I’m not saying that is bad, but why does a language need to be constantly revolutionary if it solves what it sets out to solve well? Catch up to other languages? You can easily argue the opposite, that other languages has finally catched up to PHP, ease of deployment, ease of horizontal scaling…
If you need a fast hot reload, it isn't trivial in other languages. PHP does it with no effort. Save and refresh runs the updated code instantly, not to mention asking people to run PHP app is far easier as every general hosting provider has PHP installed.
On the other hand, language structure is quite behind others but can't blame when it had been around since 20+ years ago.
The new type hinting is so basic, not sure how realistically useful it is compared to typing in TypeScript.
