PHP formatter not working

[Deleted user]

With the following configuration for php formatter:

    "php": {
        "@completion": true,
        "@formatOnSave": true,
        "@formatter": "/usr/local/bin/php-cs-fixer fix \"$file\" --rules=@Symfony,@PSR2",
        "@path": ".:./vendor"
    },

I confirmed that the php-cs-fixer runs:

docker@e5bbf908f4c3:/home/verbral/drupal-project$ /usr/local/bin/php-cs-fixer fix /home/verbral/drupal-project/src/TaskRunner/Commands/DrupalCommands.php --rules=@Symfony,@PSR2                                                            
Loaded config default.
   1) src/TaskRunner/Commands/DrupalCommands.php

Fixed all files in 0.118 seconds, 12.000 MB memory used

I'm still getting the notification that php is not supported yet:
https://github.com/c9/core/blob/master/plugins/c9.ide.format/format.js#L88-L93
Does the !emit mean that the file is not recognized as php maybe?

Error
This code could not be beautified
"php" is not supported yet

I'm having the same problem. I'm only have the problem with self-hosted Cloud9. If I use Cloud9 through AWS it works fine.

I've gone ahead and made an issue on the plugin itself in case that's where the attention is needed: c9/c9.ide.format#3
