PHPPHP V3 to PHP V4 Migration Guide

 

These docs are for PubNub 4.x for PHP which is our latest and greatest! For the docs of the older versions of the SDK, please check PubNub 3.x for PHP.

If you have questions about the PubNub for PHP SDK, please contact us at support@pubnub.com.

  • V3 exposes Pubnub
  • V4 exposes PubNub
  • V3 initiates via:
    use Pubnub\Pubnub;
    
    $pubnub = new Pubnub("my_pub_key", "my_sub_key", "my_secret_key", "my_cipher_key", true);
  • V4 initiates via:
    use PubNub\PNConfiguration;
    use PubNub\PubNub;
    
    $pnconf = new PNConfiguration();
    
    $pnconf->setSubscribeKey("my_sub_key");
    $pnconf->setPublishKey("my_pub_key");
    
    $pnconf->setSecretKey("my_secret_key");
    $pnconf->setCipherKey("my_cipher_key");
    $pnconf->setSecure(true);
    
    $pubnub = new PubNub($pnconf);
  • V3:
    $pubnub->publish('my_channel', "Hello World!");
  • V4:
    $pubnub->publish()
        ->channel("my_channel")
        ->message("Hello World!")
        ->sync();
  • V3 exposes only message subscribe callback via method params.
  • V4 exposes the functionality via listeners.
  • V4 returns a status object for each transactional request in the envelope and in the status portion of a listener or a callback.
