使用Facebook PHP SDK。我跟着一個教程之後,跑進一個問題,得到這個頁面加載,這將是錯誤,我得到:

screenshot of error

下面是代碼(應用程序ID和祕密密鑰已被刪除) 。我從教程中獲得了該文件,並從GitHub上提供的文件中填入了一些內容。

<?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''之後}自動顯示這些類型的錯誤' $ loginUrl = $ facebook-> getLoginUrl();'終止'else'。 – DCoder

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

一個括號缺失,我會建議你使用Eclipse IDE,對於這樣的錯誤,它會在編寫代碼時
