Heroku PHP and Node.js in the same app

You'll need to inform the build API that you'd like to use multiple buildpacks. Try:

$ heroku buildpacks:clear$ heroku buildpacks:add heroku/php$ heroku buildpacks:add heroku/nodejs

Then you can inspect the compiled slug via heroku run bash to verify that the bins are where you expect them to be.

php node.js heroku

The bin directory in heroku is : .heroku/php/bin/php
