Can't push PHP application to heroku

Question

I'm having trouble pushing my PHP project to Heroku. Every time I try to push I get this error:

----> Heroku receiving push
 !    Heroku push rejected, no Cedar-supported app detected.

To git@heroku.com:intense-hamlet-7552.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@heroku.com:intense-hamlet-7552.git'

It's my first time using Heroku, so here's what I've done (tried to follow this) :

1. I've created a new folder in my Eclipse workspace.
2. In this folder I've run git init.
3. I created a new PHP project (in Eclipse) in this folder.
4. I run heroku create.
5. I commit my files with TortoiseGit (I've also tried with the command-line, no difference).
6. I push the repository with git push heroku master
7. Then I get the error described above.

I've tried several times with new folders, new repositories but it happens every time.

What am I doing wrong?

EDIT: For people suggesting duplicated post:

I've seen the post Heroku push rejected, no Cedar-supported app detected which describes a problem for a Ruby application, where a Gemfile is miss-spelled. My application is a PHP application and does not have a Gemfile.

Answer 1

I figured, that Heroku didn't regonize my application as a PHP app. I created an index.php with a hello world script, and boom! Everything worked.
