Deploy PHP to Heroku
You need to create your Heroku app on the new Cedar stack. Cedar stack apps reside on the domain herokuapp.com rather than heroku.com, so you'll know if you've got the right one. Then it's really as simple as pushing your PHP files. To create an app on the Cedar stack, use:
heroku create
Or, if you'd like to set a name, (i.e. myname.herokuapp.com) use:
heroku create myapp
For the benefit of others who are not as au fait with Git, you will also need to set up, commit and push your Git repository:
git initgit add .git commit -m 'Initial commit'git push heroku masterThat's it! Good luck and have fun.
You don't need to do anything - just push your PHP code up and Heroku magic will occur - I'm no PHP guru but recently had to deploy a PHP site and I just pushed the code as is to a new Cedar app, no changing of directory structures etc and it works.
Heroku now has a guide for deploying PHP, Getting Started with PHP on Heroku, which explains that Heroku depends on Composer.
