Pubnub PHP Subscribe Function - php

Question

I need major help!
I am having troubles getting the Pubnub subscribe function to work with PHP! I can get the publish function to work, but not the subscribe function. I have copied some code straight from the Pubnub site, but I am not getting anything. Any help? Also, my PHP version is 5.2.*.
Code:
<?
include("Pubnub.php");
$pubnub = new Pubnub(
"not showing you", // PUBLISH_KEY
"not showing you", // SUBSCRIBE_KEY
"", // SECRET_KEY
false // SSL_ON?
);
$pubnub->subscribe(array(
'channel' => 'Chat',
'callback' => create_function(
'$message',
'var_dump($message); return true;'
)
));
?>

⚠️ ALERT: SDK has been upgraded ⚠️
New SDK URL: https://github.com/pubnub/php
You are asking about a way to use the Subscribe method within a web server like Apache using PHP as the dynamic processing language. Note that this is not a good practice and generally not necessary to do. You would not use the Subscribe({...}) method in a request/response.
The correct way to utilize the $pubnub->subscribe(...) method is in a long-lived PHP process, not involving a web server request-response model. Here are some examples that are confirmed to work:

Note that each example is assumed to be in a solitary PHP process outside of a web server like Apache when using the Subscribe API in PHP. However! The Publish() API can be used anywhere, including an Apache web server.
Reading History w/ Apache PHP
As an alternative you will be happy to take advantage of our HISTORY API. You can query messages in the Queue with this and receive messages. Here is an example PHP History API usage:
<?php
## Capture Publish and Subscribe Keys from Command Line
$publish_key = "YOUR_PUBLISH_KEY";
$subscribe_key = "YOUR_SUBSCRIBE_KEY";
## Require Pubnub API
require('../Pubnub.php');
## -----------------------------------------
## Create Pubnub Client API (INITIALIZATION)
## -----------------------------------------
$pubnub = new Pubnub( $publish_key, $subscribe_key );
## Get History
echo("Requesting History...\n");
$messages = $pubnub->history(array(
'channel' => 'hello_world', ## REQUIRED Channel to Send
'limit' => 100 ## OPTIONAL Limit Number of Messages
));
var_dump($messages); ## Prints Published Messages.
?>

The php subscribe function is broken and will be fixed in a new upcoming api, I talked with support recently about this and they gave me the this information.
