|  | 14 | +## Installation | 
|  | 15 | + | 
|  | 16 | +```bash | 
|  | 17 | +$ composer require enqueue/wamp | 
|  | 18 | +``` | 
|  | 19 | + | 
|  | 20 | +## Start the WAMP router | 
|  | 21 | + | 
|  | 22 | +```bash | 
|  | 23 | +$ php vendor/voryx/thruway/Examples/SimpleWsRouter.php | 
|  | 24 | +``` | 
|  | 25 | + | 
|  | 26 | +Thruway is now running on 127.0.0.1 port 9090  | 
|  | 27 | + | 
|  | 28 | + | 
|  | 29 | +## Create context | 
|  | 30 | + | 
|  | 31 | +```php | 
|  | 32 | +<?php | 
|  | 33 | +use Enqueue\Wamp\WampConnectionFactory; | 
|  | 34 | + | 
|  | 35 | +$connectionFactory = new WampConnectionFactory(); | 
|  | 36 | + | 
|  | 37 | +$context = $connectionFactory->createContext(); | 
|  | 38 | + | 
|  | 39 | +// if you have enqueue/enqueue library installed you can use a factory to build context from DSN  | 
|  | 40 | +$context = (new \Enqueue\ConnectionFactoryFactory())->create('wamp:')->createContext(); | 
|  | 41 | +``` | 
|  | 42 | + | 
|  | 43 | +## Consume message: | 
|  | 44 | + | 
|  | 45 | +Start message consumer before send message to the topic | 
|  | 46 | + | 
|  | 47 | +```php | 
|  | 48 | +<?php | 
|  | 49 | +/** @var \Enqueue\Wamp\WampContext $context */ | 
|  | 50 | + | 
|  | 51 | +$fooTopic = $context->createTopic('foo'); | 
|  | 52 | + | 
|  | 53 | +$consumer = $context->createConsumer($fooQueue); | 
|  | 54 | + | 
|  | 55 | +while (true) { | 
|  | 56 | +    if ($message = $consumer->receive()) { | 
|  | 57 | +        // process a message | 
|  | 58 | +    } | 
|  | 59 | +} | 
|  | 60 | +``` | 
|  | 61 | + | 
|  | 62 | +## Subscription consumer | 
|  | 63 | + | 
|  | 64 | +```php | 
|  | 65 | +<?php | 
|  | 66 | +use Interop\Queue\Message; | 
|  | 67 | +use Interop\Queue\Consumer; | 
|  | 68 | + | 
|  | 69 | +/** @var \Enqueue\Wamp\WampContext $context */ | 
|  | 70 | +/** @var \Enqueue\Wamp\WampDestination $fooQueue */ | 
|  | 71 | +/** @var \Enqueue\Wamp\WampDestination $barQueue */ | 
|  | 72 | + | 
|  | 73 | +$fooConsumer = $context->createConsumer($fooQueue); | 
|  | 74 | +$barConsumer = $context->createConsumer($barQueue); | 
|  | 75 | + | 
|  | 76 | +$subscriptionConsumer = $context->createSubscriptionConsumer(); | 
|  | 77 | +$subscriptionConsumer->subscribe($fooConsumer, function(Message $message, Consumer $consumer) { | 
|  | 78 | +    // process message | 
|  | 79 | +     | 
|  | 80 | +    return true; | 
|  | 81 | +}); | 
|  | 82 | +$subscriptionConsumer->subscribe($barConsumer, function(Message $message, Consumer $consumer) { | 
|  | 83 | +    // process message | 
|  | 84 | +     | 
|  | 85 | +    return true; | 
|  | 86 | +}); | 
|  | 87 | + | 
|  | 88 | +$subscriptionConsumer->consume(2000); // 2 sec | 
|  | 89 | +``` | 
|  | 90 | + | 
|  | 91 | +## Send message to topic | 
|  | 92 | + | 
|  | 93 | +```php | 
|  | 94 | +<?php | 
|  | 95 | +/** @var \Enqueue\Wamp\WampContext $context */ | 
|  | 96 | + | 
|  | 97 | +$fooTopic = $context->createTopic('foo'); | 
|  | 98 | +$message = $context->createMessage('Hello world!'); | 
|  | 99 | + |
