This simple command-line application demonstrates how to invoke Google IOT API from PHP. These samples are best seen in the context of the Official API Documentation.

1. Enable APIs - Enable the IOT API and create a new project or select an existing project.
2. Download The Credentials - Click "Go to credentials" after enabling the APIs. Click "New Credentials" and select "Service Account Key". Create a new service account, use the JSON key type, and select "Create". Once downloaded, set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of the JSON key that was downloaded.
3. Clone the repo and cd into this directory

    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
    $ cd php-docs-samples/iot

4. Install dependencies via Composer. Run php composer.phar install (if composer is installed locally) or composer install (if composer is installed globally).

5. Run php iot.php. The following commands are available:

   create-es-device      Create a new device with the given id, using ES256 for authentication.
   create-registry       Creates a registry and returns the result.
   create-rsa-device     Create a new device with the given id, using RS256 for authentication.
   create-unauth-device  Create a new device without authentication.

   delete-registry       Deletes the specified registry.
   get-device            Retrieve the device with the given id.
   get-device-configs    Lists versions of a device config in descending order (newest first).
   get-device-state      Retrieve a device's state blobs.
   get-iam-policy        Retrieves IAM permissions for the given registry.
   get-registry          Retrieves a device registry.
   help                  Displays help for a command
