Feature Support for PubNub PHP SDK

Access Manager

PubNub provides builtin enterprise-grade security with fine-grained access control to all of your PubNub applications with Access Manager, Message Layer encryption with AES256, and Transport Layer Security with TLS and SSL.
GrantThis function establishes access permissions for Access Manager by setting the read or write attributes.
Root permissions for the Access ManagerWhen you init with secret key, you get root permissions for the Access Manager. With this feature you don't have to grant access to your servers to access channel data. The servers get all access on all channels.

Channel Groups

Channel Groups allows PubNub developers to bundle thousands of channels into a group that can be identified by name. These Channel Groups can then be subscribed to, receiving data from the many backend-channels the channel group contains.
Add ChannelsAdd channel to a channel group.
Remove ChannelsRemove channel from channel group.

List Channels In Channel GroupList all channels of a channel group.

Include TimetokenWhether event dates time tokens should be included in response or not.
Start EndTime token delimiting the start/end of time slice (exclusive) to pull messages from.
Count of Messages on ChannelsThe API is a history based API that simply does a mostly normal history operation but instead of returning the messages in a channel it returns the count of messages. Without actually calling history on those channels this API gives you the ability to say if there are messages in the chat channel you can go look at further.
CountSpecifies the number of historical messages to return.
