A few months ago I was tasked with porting an internally used Node.js script to PHP 5.6. The code made heavy use of nested async callbacks and other patterns frequently only seen in Javascript codebases. I thought I'd have to rewrite most of it from scratch, but the PHP code ended up nearly identical to the original Javascript. Line-for-line, ignoring minor syntactical differences (like the $ in vars), these two ~400 line scripts ended up being 98% identical. Anonymous functions, closures, async calls, syntax short-hands... PHP has it all.
