问题 I have the server configuration to speak to the Android clients as: <?php require_once("mysql.class.php"); require_once("lib/autoloader.php"); // Setting up the PubNub Server: use Pubnub\Pubnub; $pubnub = new Pubnub( "pub-c...", ## PUBLISH_KEY "sub-c..." ## SUBSCRIBE_KEY ); // Publishing : $post_data = json_encode(array("type"=> "groupMessage", "data" => array("chatUser" => "SERVER", "chatMsg" => "Now lets talk", "chatTime"=>1446514201516))); $info = $pubnub->publish('MainChat', $post_data);

问题 The page about the PubNub History API states that The history() function returns a list of up to 100 messages, the start time token and the ending time token. Is there a way to retrieve more than the 100 messages?

问题 In my project I have to send user's location periodically (E.g. 30Sec) to server using Android application and the PHP server returns nearest users and app displays them on the map.
