title: Azure send Push Notification to Multiple Devices/Broadcast
body: <p>I used <code>AWS SNS</code> to send notification on multiple devices, in <code>AWS SNS</code> i created some <code>Topics</code> and <code>Subscribe</code> <code>Endpoint ARN</code> (user device in AWS) to Topic and <code>Publish</code> notification on Topic to send notification to all subscribers by <code>PHP</code>.</p>
  
  <p>Now i am switching to Azure, and want to implement same application in <code>PHP</code>, after some research i find out this link:</p>
  
  <p><a href="https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-php-how-to-use-topics-subscriptions" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-php-how-to-use-topics-subscriptions</a></p>
  
  <p>Is there any way to implement my requirement without using <code>Service Bus</code>. Also dosen't understand Why Topic and Subscription are in <code>Service Bus</code> and unable to use it directly. Or is there some reason to use it via <code>Service Bus</code>.</p>
