PHP picks up ideas and syntax from many other languages. I'm happy about it, because it popularizes and normalizes concepts that used to be niche or advanced.

PHP picks up ideas and syntax from many other languages. I'm happy about it, because it popularizes and normalizes concepts that used to be niche or advanced. C established a lot of common syntax, and there's some consensus for post-C syntax emerging, like `name: type` syntax, `match` expressions, non-nullable types and operators for them. Nowadays `[1,2,3]` seems like an obvious syntax for array literals, but it wasn't obvious before JSON and other languages converging on it.
