Get list size - PHP example

I thought I would throw up a php example on how to get the size of a list.

    //Sample using the CMBase.php wrapper
    //Relative path to CMBase.php. This example assumes the file is in the same folder
    //Your API Key. Go to to see where to find this and other required keys
    $api_key = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
    $client_id = null;
    $campaign_id = null;
    $list_id = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
    $cm = new CampaignMonitor( $api_key, $client_id, $campaign_id, $list_id );
    //Optional statement to include debugging information in the result
    //$cm->debug_level = 1;
    //Subscribers added after the Date value specified will be returned. Must be in the format YYYY-MM-DD HH:MM:SS.
    $Date = '2009-05-01 01:01:00';
    //This is the actual call to the method
    $result = $cm->subscribersGetActive($Date);
    if($result['Result']['Code'] == 0)
        echo 'Success';
        echo 'Error : ' . $result['Result']['Message'];
    //check the size of the array
    $list_size = sizeof($result['anyType']['Subscriber']);
    echo '<p>Size of list: '.$list_size.'</p>';
    //Print out the debugging info

I hope that I've done this right - It works fine for me. It's really basic but handy when calculating the cost of a campaign.

Please let me know if there is anything wrong with this and I'll update it accordingly.
