解析错误：语法错误，Facebook应用程序中的意外$结局

使用Facebook PHP SDK。我跟着一个教程之后，跑进一个问题，得到这个页面加载，这将是错误，我得到：

screenshot of error

下面是代码（应用程序ID和秘密密钥已被删除）。我从教程中获得了该文件，并从GitHub上提供的文件中填入了一些内容。

<?php 

require 'src/facebook.php' 

$app_id = ""; // has been removed 
$secret = ""; // has been removed 
$app_url = "http://apps.facebook.com/instahomework/"; 

// Create our Application instance (replace this with your appId and secret). 
$facebook = new Facebook(array(
    'appId' => $app_id, 
    'secret' => $secret, 
)); 

// Get User ID 
$user = $facebook->getUser(); 

// We may or may not have this data based on whether the user is logged in. 
// 
// If we have a $user id here, it means we know the user is logged into 
// Facebook, but we don't know if the access token is valid. An access 
// token is invalid if the user logged out of Facebook. 

if ($user) { 
    try { 
    // Proceed knowing you have a logged in user who's authenticated. 
    $user_profile = $facebook->api('/me'); 
    } catch (FacebookApiException $e) { 
    error_log($e); 
    $user = null; 
    } 
} 

// Login or logout url will be needed depending on current user state. 
if ($user) { 
    $logoutUrl = $facebook->getLogoutUrl(); 
} else { 
    $loginUrl = $facebook->getLoginUrl(); 

// This call will always work since we are fetching public data. 
$naitik = $facebook->api('/naitik');

添加了''之后}自动显示这些类型的错误' $ loginUrl = $ facebook-> getLoginUrl（）;'终止'else'。 – DCoder

if ($user) { 
$logoutUrl = $facebook->getLogoutUrl(); 
} else { 
    $loginUrl = $facebook->getLoginUrl(); 
}

一个括号缺失，我会建议你使用Eclipse IDE，对于这样的错误，它会在编写代码时

好的，谢谢，是的，我在Sublime上，所以我会研究Eclipse。 – JGallardo
