[Codeigniter] Codeigniter 整合 AmfPHP

Codeigniter  搭配開發 FLEX 專案時，要如何透過 Amfphp 傳送資料至前端 FLEX 處理呢?
整合步驟如下：

所需套件：
1. Codeigniter 1.7.1 版本以上
2. AMFPHP 1.9 版本以上

整合流程：
1. 先將解壓縮後的 amfphp 資料夾移至 Codeigniter 開發目錄 (預設路徑為 system\application\) 下的 libraries 目錄裡
2. 建立 amfphp gateway controller 檔案  ( amf_gateway.php )

//This file replaces the need for gateway.php

//setup netConnection to ‘/index.php/amf_gateway’

class Amf_gateway extends Controller
{
  public function __construct()
  {
    parent::Controller();
    //Start our library (keep reading the tutorial)
    $this->load->library('amfci');
    //Set new include path for services
    ini_set('include_path', ini_get('include_path') . PATH_SEPARATOR . AMFSERVICES);
  }

//startup the amf gateway service
public function index()
 {
  $this->amfci->service();
 }
} 

3. 建立 amfci_db 檔案至 libraries/amfphp/services/ 目錄下

require_once(BASEPATH.'/../system/libraries/Model.php');


4. 建立 amfci class 檔案至 libraries 目錄下


//This file is the new amfphp library for CI
//It it loaded from the amf_gateway controller, and binds all of it together

class Amfci
{
  public $gateway;
  public $CI;
  public function __construct()
  {
    $this->CI = get_instance();
    require realpath(dirname(__FILE__))."/amfphp/globals.php";
    require realpath(dirname(__FILE__))."/amfphp/core/amf/app/Gateway.php";
    define('AMFSERVICES', realpath(dirname(__FILE__))."/amfphp/services");

    $this->gateway = new Gateway();
    $this->gateway->setCharsetHandler("utf8_decode", "ISO-8859-1", "ISO-8859-1");
    $this->gateway->setLooseMode();
    $this->gateway->setErrorHandling(E_ALL ^ E_NOTICE);
    $this->gateway->setClassMappingsPath(AMFSERVICES.'/vo');
    $this->gateway->setClassPath(AMFSERVICES);

    if(PRODUCTION_SERVER)
    {
      //Disable profiling, remote tracing, and service browser
      $this->gateway->disableDebug();
    }
  }

  public function service()
  {
    $this->gateway->service();
  }
}

5.完成以上四個步驟後，基本的 amfphp 整合已大致完成，接下來就是對應前端的 Service 開發過程

 1.首先在 libraries\amfphp\services 下建立 amfphp Service 

2.載入所需的 model class

3.透過 service 繼承 model 取用存取後端資料方法

require_once('amfci_db.php');

// Use this path if you are using a module (ie, MatchBox)
// require_once(AMFSERVICES.'/../../../modules/test_shop/models/product_model.php');
require_once(AMFSERVICES.'/../../../models/product_model.php');
class product_service extends Product_model
{

}

6.最後建立 Flex 專案利用 RemoteObject 建立 amfphp gateway 取用 Service
