Yes, Racket is Scheme, but it's much more practical than a vanilla R6RS implementation, and it packs a lot of libraries, tool support, and clear and simple end-user documentation, exactly the kinds of things that people mean when they say 'user-friendly'

What, specifically, makes PHP easier to pick up than Racket? Everyone I know who got started with PHP took an off-the-shelf lamp installation and started spitting out simple webpages. By that measure, Racket is at least as easy - download it, and you have a webserver, templating language, and a package manager with plenty of database toolkits.

If you're simply saying that PHP doesn't burden a noob with features like macros and continuations: You can write Racket code that's just as stupid as what you have to write in PHP, but unlike PHP, once you've gotten over the learning hump, there's a nice language waiting for you on the other side.
