PHP Alexa Helpers
=================

[](#php-alexa-helpers)

A library to ease development when working with the Amazon Alexa API

Installation
------------

[](#installation)

```
composer require nomisoft/php-alexa-helper

```

Usage
-----

[](#usage)

### Requests

[](#requests)

This will capture the JSON from the POST request

```
use \Alexa\Request\AlexaRequest;
$alexaRequest = AlexaRequest::fromRequest();
```

If you've already captured the posted JSON and have it in a variable you can pass it in to the constructor of the AlexaRequest class

```
$alexaRequest = new AlexaRequest($json);
```

The $alexaRequest object now behaves like an object representing the JSON posted by the Alexa API. You can directly access the properties as they match the JSON for example:

```
$alexaRequest->version;
$alexaRequest->session->application->applicationId;
$alexaRequest->request->intent->slots->ZodiacSign->value;
```

There are a few shortcut functions available

**$alexaRequest->getType()** is a shortcut returning the value of request->type from the JSON

**$alexaRequest->getIntent()** is a shortcut returning the value of request->intent->name from the JSON

**$alexaRequest->getSlots()** returns a key/value array of the intent slots. For example `"slots": { "ZodiacSign": { "name": "ZodiacSign", "value": "virgo" } }` would return `array('ZodiacSign'=>'virgo')`

### Validating requests

[](#validating-requests)

Skills being submitted for Alexa approval also need an extra step in verifying the requests come from Amazon. The RequestValidator class will do all necessary timestamp and certificate checks.

```
use \Alexa\Request\AlexaRequest;
use \Alexa\Request\RequestValidator;
$alexaRequest = AlexaRequest::fromRequest();
$validator = new RequestValidator($request);
if (!$validator->validate('YOUR_APP_ID')) {
    print_r($validator->getErrors());
}
```

### Responses

[](#responses)

To respond to the Alexa request you can construct an OutputSpeech object

```
use \Alexa\Request\AlexaRequest;
use \Alexa\Request\OutputSpeech;
$response = new AlexaResponse();
$speech = new OutputSpeech();
$speech->setText('Hello World');
$response->setOutputSpeech($speech);
```

When you invoke your Alexa skill your Amazon Echo (or other Alexa enabled device) will respond by saying 'Hello World'

By default a 'PlainText' type of speech response will be used. You can also respond using SSML

```
$speech = new OutputSpeech();
$speech->setType('SSML');
$speech->setText('Hello world.');
```

If you wish to also send a 'card' response which is shown on screen in the Alexa app you can create a Card object. The below example is for a 'Simple' card with just some text

```
use \Alexa\Request\Card;
$card = new Card();
$card->setContent('Hello World');
$response->setCard($card);
$response->render();
```

As well as setting the cards text content you can also set a title and return images to be displayed

```
$card = new Card();
$card->setType('Standard');
$card->setTitle('Hello World Title');
$card->setText('Hello World Content');
$card->setSmallImage('http://example.com/small.jpg');
$card->setLargeImage('http://example.com/large.jpg');
$response->setCard($card);
```

The AlexaResponse class is JSON serializable so to return your response to Amazon just `echo json_encode($response);` or call `$response->render()`. If you're using Symfony you might return the json with JsonResponse from your controller like:

```
$jsonResponse = new \Symfony\Component\HttpFoundation\JsonResponse($response);
return $jsonResponse;
```
