Syntax error, unexpected '{' when using the Facebook PHP-SDK

问题描述:

I'm trying to get my team's Flash project on Facebook, but I cannot get any of the PHP-SDK examples to work. I've followed several examples, such as this new one on github (here). However, I keep getting a parse error:

Parse error: syntax error, unexpected '{' in

/home/content/r/a/s/rashomon/html/projects/facebook/test/hellomyflash/index.php

on line 36

I downloaded the latest PHP-SDK. Here's my file structure:

.../hellomyflash/

index.php

src/base_facebook.php

src/facebook.php

src/fb_ca_chain_bundle.crt

The only two lines I changed in index.php are the appId and secret.

index.php :

<?php

require '../src/facebook.php';

// Create our Application instance (replace this with your appId and secret).

$facebook = new Facebook(array(

'appId' => '###############',

'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');

?>

<?php endif ?>

<h3>Public profile of Naitik</h3>

<?php echo $naitik['name']; ?>

I got the same "unexpected '{'" error when following this example.

What am I doing wrong???

网友答案:

Your server is most likely running PHP4, the code provided is for PHP5.

PHP4 does not have try/catch blocks.

网友答案:

If you go in to "facebook.php" and "base_facebook.php", the close tags for php is missing, " ?> " at the bottom of the page. I've heard that this caused problems for some, and it got fixed when they added close tags. You can try ;)

But after seeing the answer from the dude over me, that's probably the correct answer! :p
