If you want to ride a bike, you can ride the bike. If you want to do tricks, you can do tricks.
PHP makes simple stuff easy and difficult stuff possible. (But you're not going to win the Tour de France on a BMX bike.)
Nowadays, a lot of other things also do this, but PHP was the first to really "get" this. I understand it's not for everybody, and for certain things, other languages are certainly better. But there's precious little that you can't do with PHP, since it's been around for so long and has been growing with the Web from pretty much the very beginning.
How should I interpret this? The language is cool? Can perform cool tricks?
