sendAnnouncement() allows you to dynamically send announcements to a particular user.

The API

sendAnnouncement($to,$message);

Sample Code

Ideal use of this function is to inform the user when an activity happens. Say you have a function which posts messages to a user’s wall.

function wallPost($fromID, $toID, $fromName, $toName, $message) {
    // Perform actual wall post

    include_once (cometchat/cometchat_init.php);
    sendAnnouncement($toID,"You have a new wall post from ".$fromName);
}
