PHP Push API Walkthrough

Javascript

PUBNUB.subscribe( { channel : 'my_test_channel' },
function(message) {
    if ('some_text' in message) {
        alert(message.some_text);
    }
} );

Javascript2

PUBNUB.publish({
    channel : 'extra_cool_channel',
    message : { 'some_var' : 'what up?' }
});

PHP

## Publish Messages To a JavaScript Browser
$pubnub = new Pubnub( 'publish_key', 'subscribe_key' );
$pubnub->publish(array(
    'channel' => 'my_test_channel',
    'message' => array( 'some_text' => 'hello!' )
));

PHP Listens for a Message

$pubnub->subscribe(array(
    'channel'  => 'extra_cool_channel',
    'callback' => function($message) {
        var_dump($message);
        return true;         ## continue listening
    }
));

PHP Output

array(1) {
    ["some_var"]=>
    string(8) "what up?"
}
