PubNub PHP SDK V4 Issues

Any idea why this fails?

Here is a PubNub PHP SDK V4 working code which throws the error:

Code:
PHP Parse error:  syntax error, unexpected 'use' (T_USE) in  .....

According to the PubNub docs, V4 of the PHP SDK support PHP v5.6, so I'm really confused as to why this error.

Directly from this PubNub here:

Code:
<?php
require_once('vendor/autoload.php');

use PubNub\PubNub;
use PubNub\Enums\PNStatusCategory;
use PubNub\Callbacks\SubscribeCallback;
use PubNub\PNConfiguration;
 
class MySubscribeCallback extends SubscribeCallback {
    function status($pubnub, $status) {
        if ($status->getCategory() === PNStatusCategory::PNUnexpectedDisconnectCategory) {
            // This event happens when radio / connectivity is lost
        } else if ($status->getCategory() === PNStatusCategory::PNConnectedCategory) {
            // Connect event. You can do stuff like publish, and know you'll get it
            // Or just use the connected event to confirm you are subscribed for
            // UI / internal notifications, etc
        } else if ($status->getCategory() === PNStatusCategory::PNDecryptionErrorCategory) {
            // Handle message decryption error. Probably client configured to
            // encrypt messages and on live data feed it received plain text.
        }
    }
 
    function message($pubnub, $message) {
        // Handle new message stored in message.message
    }
 
    function presence($pubnub, $presence) {
        // handle incoming presence data
    }
}
 
$pnconf = new PNConfiguration();
$pubnub = new PubNub($pnconf);
 
$pnconf->setSubscribeKey("my_sub_key");
$pnconf->setPublishKey("my_pub_key");
 
$pubnub->addListener($subscribeCallback);
 
// Subscribe to a channel, this is not async.
$pubnub->subscribe()
    ->channels("hello_world")
    ->execute();
 
// Use the publish command separately from the Subscribe code shown above.
// Subscribe is not async and will block the execution until complete.
$result = $pubnub->publish()
              ->channel("hello_world")
              ->message("Hello PubNub")
              ->sync();
 
print_r($result);

PHP_CHECK_SYNTAX(3)							 1						       PHP_CHECK_SYNTAX(3)

php_check_syntax - Check the PHP syntax of (and execute) the specified file

SYNOPSIS
bool php_check_syntax (string $filename, [string &$error_message]) DESCRIPTION
Performs a syntax (lint) check on the specified $filename testing for scripting errors. This is similar to using php -l from the commandline except that this function will execute (but not output) the checked $filename. For example, if a function is defined in $filename, this defined function will be available to the file that executed php_check_syntax(3), but output from $filename will be suppressed. Note For technical reasons, this function is deprecated and removed from PHP. Instead, use php -l somefile.php from the commandline. PARAMETERS
o $filename - The name of the file being checked. o $error_message - If the $error_message parameter is used, it will contain the error message generated by the syntax check. $error_message is passed by reference. RETURN VALUES
Returns TRUE if the lint check passed, and FALSE if the link check failed or if $filename cannot be opened. CHANGELOG
+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.0.5 | | | | | | | This function was removed from PHP. | | | | | 5.0.3 | | | | | | | Calling exit(3) after php_check_syntax(3) | | | resulted in a Segfault. | | | | | 5.0.1 | | | | | | | $error_message is passed by reference. | | | | +--------+---------------------------------------------------+ EXAMPLES
php -l somefile.php The above example will output something similar to: PHP Parse error: unexpected T_STRING in /tmp/somefile.php on line 81 SEE ALSO
