Having actually deployed a PHP project on Heroku, this would have been a godsend at the time I started. While Heroku unofficially supports PHP (for Facebook apps), their default PHP stack leaves a lot to be desired. In particular, lack of default zlib and multi-byte string support caused all sorts of chaos. I don't blame Heroku for this, since they don't officially support PHP, but it was a PITA. Luckily, someone else had already encountered these issues, and I was able to plunk in some pre-built libs. I chose Heroku because I wanted to familiarize myself with the top PaaS provider, but if I had to do it again, I would have bitten the bullet, learned a new language, and not mentioned it to the client. Or, if I were forced to use PHP, I'd have gone with a provider where it's a first-class citizen.
