包括外部php文件-facebook sdk 4.0 php文件。

Question

通常这可行，但我不知道为什么不可行。 它给了我以下错误：致命错误：在第9行的C：\\ xampp \\ htdocs \\ app \\ index.php中找不到类'FacebookSession'

在我的index.php中：

 <?php
  include 'include.php';
  --- rest of my code
  ?>

在我的include.php中：

 <?php
  require_once( 'Facebook/HttpClients/FacebookHttpable.php' );
  require_once( 'Facebook/HttpClients/FacebookCurl.php' );
  require_once( 'Facebook/HttpClients/FacebookCurlHttpClient.php' );

  require_once( 'Facebook/Entities/AccessToken.php' );
  require_once( 'Facebook/Entities/SignedRequest.php' );

  require_once( 'Facebook/FacebookSession.php' );
  require_once( 'Facebook/FacebookRedirectLoginHelper.php' );
  require_once( 'Facebook/FacebookRequest.php' );
  require_once( 'Facebook/FacebookResponse.php' );
  require_once( 'Facebook/FacebookSDKException.php' );
  require_once( 'Facebook/FacebookRequestException.php' );
  require_once( 'Facebook/FacebookServerException.php' );
  require_once( 'Facebook/FacebookOtherException.php' );
  require_once( 'Facebook/FacebookAuthorizationException.php' );
  require_once( 'Facebook/GraphObject.php' );
  require_once( 'Facebook/GraphSessionInfo.php' );

  use Facebook\HttpClients\FacebookHttpable;
  use Facebook\HttpClients\FacebookCurl; 
  use Facebook\HttpClients\FacebookCurlHttpClient;

  use Facebook\Entities\AccessToken;
  use Facebook\Entities\SignedRequest;

  use Facebook\FacebookSession;
  use Facebook\FacebookRedirectLoginHelper;
  use Facebook\FacebookRequest;
  use Facebook\FacebookResponse;
  use Facebook\FacebookSDKException;
  use Facebook\FacebookRequestException;
  use Facebook\FacebookServerException;
  use Facebook\FacebookOtherException;
  use Facebook\FacebookAuthorizationException;
  use Facebook\GraphObject;
  use Facebook\GraphSessionInfo;
  ?>

我一定很想念一些愚蠢的东西。 因为这应该工作？

UPDATE

Trouble Shoot Your Code

foo foo foo
echo '1';
foo foo foo 
echo '2';
foo foo foo
echo '3';

这是文件路径问题。

这就是我的文件结构的工作方式，

根目录/

actions/fbhandshakes
facebook/ //this is the api
includes header.php
index.php

在动作/ fb握手中

// include required classes from Facebook SDK
require_once( 'facebook/src/Facebook/FacebookHttpable.php' );
require_once( 'facebook/src/Facebook/FacebookCurl.php' );
require_once( 'facebook/src/Facebook/FacebookCurlHttpClient.php' );
require_once( 'facebook/src/Facebook/FacebookSession.php' );
require_once( 'facebook/src/Facebook/FacebookRedirectLoginHelper.php' );
require_once( 'facebook/src/Facebook/FacebookRequest.php' );
require_once( 'facebook/src/Facebook/FacebookResponse.php' );
require_once( 'facebook/src/Facebook/FacebookSDKException.php' );
require_once( 'facebook/src/Facebook/FacebookRequestException.php' );
require_once( 'facebook/src/Facebook/FacebookOtherException.php' );
require_once( 'facebook/src/Facebook/FacebookAuthorizationException.php' );
require_once( 'facebook/src/Facebook/GraphObject.php' );
require_once( 'facebook/src/Facebook/GraphSessionInfo.php' );

// Called class with namespace
use Facebook\FacebookHttpable;
use Facebook\FacebookCurl;
use Facebook\FacebookCurlHttpClient;
use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookOtherException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;
use Facebook\GraphSessionInfo;
// This is the rest of the my facebook call from here down ...

在header.php中，我包括整个facebook call

require_once( 'actions/fbHandshake.php' ); 

然后，将标头添加到我的index.php file.

require_once( 'includes/header.php' );
