# Mailgun PHP client

This is the Mailgun PHP SDK. This SDK contains methods for easily interacting 
with the Mailgun API. 
Below are examples to get you started. For additional examples, please see our 
official documentation

**This is the documentation for dev-master. You can find documentation for the latest stable 
release [here](https://github.com/mailgun/mailgun-php/tree/v2.1.2).**

## Installation

To install the SDK, you will need to be using [Composer](http://getcomposer.org/) 
in your project. 
If you aren't using Composer yet, it's really simple! Here's how to install 
composer:

```bash
curl -sS https://getcomposer.org/installer | php
```

The Mailgun api client is not hard coupled to Guzzle or any other library that sends HTTP messages. It uses an abstraction 
called HTTPlug. This will give you the flexibilty to choose what PSR-7 implementation and HTTP client to use. 

If you just want to get started quickly you should run the following command: 

```bash
php composer.phar require mailgun/mailgun-php php-http/curl-client guzzlehttp/psr7
```

### Why requiring so many packages?

Mailgun has a dependency on the virtual package
[php-http/client-implementation](https://packagist.org/providers/php-http/client-implementation) which requires you to install **an** adapter, but we do not care which one. That is an implementation detail in your application. We also need **a** PSR-7 implementation and **a** message factory. 

You do not have to use the `php-http/curl-client` if you do not want to. You may use the `php-http/guzzle6-adapter`. Read more about the virtual packages, why this is a good idea and about the flexibility it brings at the [HTTPlug docs](http://docs.php-http.org/en/latest/httplug/users.html).

## Usage

You should always use Composer's autoloader in your application to automatically load the your dependencies. All examples below assumes you've already included this in your file:

```php
require 'vendor/autoload.php';
use Mailgun\Mailgun;
```

Here's how to send a message using the SDK:

```php
# First, instantiate the SDK with your API credentials
$mg = Mailgun::create('key-example');

# Now, compose and send your message.
# $mg->messages()->send($domain, $params);
$mg->messages()->send('example.com', [
  'from'    => 'bob@example.com',
  'to'      => 'sally@example.com',
  'subject' => 'The PHP SDK is awesome!',
  'text'    => 'It is so simple to send a message.'
]);
```

Attention: `$domain` must match to the domain you have configured on [app.mailgun.com](https://app.mailgun.com/app/domains).

### All usage examples

You find more detailed documentation at [/doc](doc/index.md) and on 
[https://documentation.mailgun.com](https://documentation.mailgun.com/api_reference.html).

### Response

The result of an API call is, by default, a domain object. This will make it easy
to understand the response without reading the documentation. One can just read the
doc blocks on the response classes. This provides an excellent IDE integration.
 
```php
$mg = Mailgun::create('key-example');
$dns = $mg->domains()->show('example.com')->getInboundDNSRecords();

foreach ($dns as $record) {
  echo $record->getType();
}
```

If you'd rather work with an array than an object you can inject the `ArrayHydrator`
to the Mailgun class. 

```php
use Mailgun\Hydrator\ArrayHydrator;

$configurator = new HttpClientConfigurator();
$configurator->setApiKey('key-example');

$mg = Mailgun::configure($configurator, new ArrayHydrator());
$data = $mg->domains()->show('example.com');

foreach ($data['receiving_dns_records'] as $record) {
  echo isset($record['record_type']) ? $record['record_type'] : null;
}
```

You can also use the `NoopHydrator` to get a PSR7 Response returned from 
the API calls. 

**Warning: When using `NoopHydrator` there will be no exceptions on a non-200 response.**

### Debugging

Debugging the PHP SDK can be really helpful when things aren't working quite right. 
To debug the SDK, here are some suggestions: 

Set the endpoint to Mailgun's Postbin. A Postbin is a web service that allows you to 
post data, which is then displayed through a browser. This allows you to quickly determine
what is actually being transmitted to Mailgun's API. 

**Step 1 - Create a new Postbin.**  
Go to http://bin.mailgun.net. The Postbin will generate a special URL. Save that URL. 

**Step 2 - Instantiate the Mailgun client using Postbin.**  

*Tip: The bin id will be the URL part after bin.mailgun.net. It will be random generated letters and numbers. 
For example, the bin id in this URL, http://bin.mailgun.net/aecf68de, is "aecf68de".*

```php
$configurator = new HttpClientConfigurator();
$configurator->setEndpoint('http://bin.mailgun.net/aecf68de');
$configurator->setDebug(true);
$mg = Mailgun::configure($configurator);

# Now, compose and send your message.
$mg->messages()->send('example.com', [
  'from'    => 'bob@example.com', 
  'to'      => 'sally@example.com', 
  'subject' => 'The PHP SDK is awesome!', 
  'text'    => 'It is so simple to send a message.'
]);
```
### Additional Info

For usage examples on each API endpoint, head over to our official documentation 
pages. 

This SDK includes a [Message Builder](src/Mailgun/Messages/README.md), 
[Batch Message](src/Mailgun/Messages/README.md) and [Opt-In Handler](src/Mailgun/Lists/README.md) component.

Message Builder allows you to quickly create the array of parameters, required 
to send a message, by calling a methods for each parameter.
Batch Message is an extension of Message Builder, and allows you to easily send 
a batch message job within a few seconds. The complexity of 
batch messaging is eliminated! 

## Framework integration

If you are using a framework you might consider these composer packages to make the framework integration easier.
