Responder

Simple PHP Responder Utility Library for API Development

Installation

Begin by installing this package through Composer. Edit your project's composer.json file to require Nathanmac/Responder.

"require": {
	"Nathanmac/Responder": "2.*"
}

Next, update Composer from the Terminal:

composer update

Laravel Users

If you are a Laravel user, then there is a service provider that you can make use of to automatically prepare the bindings and such.

// app/config/app.php

'providers' => [
    '...',
    'Nathanmac\Utilities\Responder\ResponderServiceProvider'
];

When this provider is booted, you'll have access to a helpful Responder facade, which you may use in your controllers.

public function index()
{
    Responder::json($payload);         // Array > JSON
    Responder::xml($payload);          // Array > XML
    Responder::yaml($payload);         // Array > YAML
    Responder::querystr($payload);     // Array > Query String
    Responder::serialize($payload);    // Array > Serialized Object
    Responder::bson($payload);         // Array > BSON
    Responder::msgpack($payload);      // Array > MessagePack
}

Responder Functions

$responder->xml($payload);          // Array > XML
$responder->yaml($payload);         // Array > YAML
$responder->querystr($payload);     // Array > Query String
$responder->serialize($payload);    // Array > Serialized Object
$responder->bson($payload);         // Array > BSON
$responder->msgpack($payload);      // Array > MessagePack

Respond with Automatic Detection

$responder = new Responder();

$body = array(
    'message' => array(
        'to' => 'Jack Smith',
        'from' => 'Jane Doe',
        'subject' => 'Hello World',
        'body' => 'Hello, whats going on...'
    )
);

header("Content-Type: {$responder->getContentType()}");
print $responder->payload($body);

Respond with JSON

$responder = new Responder();

$body = array(
    'message' => array(
        'to' => 'Jack Smith',
        'from' => 'Jane Doe',
        'subject' => 'Hello World',
        'body' => 'Hello, whats going on...'

$responder = new Responder();

$body = array(

        'subject' => 'Hello World',
        'body' => 'Hello, whats going on...'
    )
);

header('Content-Type: application/x-msgpack');
print $responder->msgpack($body);

Custom Responders/Formatters

You can make your own custom responders/formatters by implementing FormatInterface, the below example demostrates the use of a custom responder/formatter.

use Nathanmac\Utilities\Responder\Formats\FormatInterface;

/**
 * Custom Formatter
 */

class CustomFormatter implements FormatInterface {
    /**
     * Generate Payload Data
     *
     * @param array $payload
     *
     * @return string
     *
     * @throws ResponderException
     */
    public function generate($payload)
    {
        $payload; // Raw payload array

        $output = // Process raw payload array to formatted data

        return $output; // return data string
    }
}

Using the CustomFormatter

use Acme\Formatters\CustomFormatter;

$responder = new Responder();
$generated = $responder->generate(['raw' => 'payload', 'data'], new CustomFormatter());

Register the CustomFormatter

use Acme\Formatters\CustomFormatter;

$responder = new Responder();
$responder->registerFormat('application/x-custom-format', 'Acme\Formatters\CustomFormatter');
$responder->payload('application/x-custom-format');

Testing

To test the library itself, run the PHPUnit tests:
