如何在heroku中添加并发到php应用程序？

Question

i'm developing a simple php app for SEO data retrieval, using this library: https://github.com/eyecatchup/SEOstats

You can check the web app here:

I'm deploying it to heroku, looking to run multiple php processes in a single dyno. Is there anything similar to unicorn for php in heroku[1]?
