I can't deploy my php app to Heroku

Question

This is the first time I get in touch with Heroku (it's really amazing). I followed these steps to deploy my very first app to heroku.

git init
git add .
git commit -m 'first commit'
heroku create abcfirstapp
git remote add origin git@heroku.com:abcfirstapp.git
git push heroku master

And I got the error like

Heroku push rejected, no Cedar--supported app detected To git@heroku.com:abcfirstapp.git [remote.rejected] master -> master (pre-receive hook declined) error: failed to push some refs to 'git@heroku.com:abcfirstapp.git'

I'm quite sure that my php file is written probably since it runs well with my local xampp server

<?PHP phpinfo(); ?>

One more problem is: when I try to pull from heroku using

git pull heroku master

I got an error

fatal: couldn't find remote ref master

Could anyone help me out please?

Thanks

Answer 1

The default PHP buildpack detects PHP apps by looking for index.php in the repo root. Do you have one of those?

Alternatively, you can hardcode the buildpack:

heroku config:add BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-php

Answer 2

no Cedar--supported app detected

PHP is not a natively supported language on Heroku, outside of Facebook apps I suppose. You'll need to utilize something like a Third Party Buildpack .

Answer 3

It looks like the docs (Apr 2015) recommend you set a custom buildpack via:

heroku buildpack:set https://github.com/heroku/heroku-buildpack-php

https://devcenter.heroku.com/articles/buildpacks

需要的是至少一个空的composer.json推送这个，然后重新部署
