plug: i'm co-founder of PHP-only-PaaS fortrabbit — seeing Heroku move in our direction shows me that we are doing something right. We see a lot of momentum in the PHP community — some call it a PHP renaissance. Laravel, Composer and lately Facebooks input with HHVM (& Hack) are the cornerstones. Of course PHP is not everyones cup of tea, but something to be taken seriously.
