    text
    copied!<p>I am able to manually get the user's data, but not programatically.</p> <p>Using the server side code, as it is, from - <a href="https://developers.facebook.com/docs/authentication/" rel="nofollow">https://developers.facebook.com/docs/authentication/</a></p> <pre><code> &lt;?php $app_id = "MY_APP_ID"; $app_secret = "MY_APP_SECRET"; $my_url = "ADDRESS_OF_CURRENT_PAGE"; session_start(); $code = $_REQUEST["code"]; if(empty($code)) { $_SESSION['state'] = md5(uniqid(rand(), TRUE)); //CSRF protection $dialog_url = "https://www.facebook.com/dialog/oauth?client_id=" . $app_id . "&amp;redirect_uri=" . urlencode($my_url) . "&amp;state=" . $_SESSION['state']; echo("&lt;script&gt; top.location.href='" . $dialog_url . "'&lt;/script&gt;"); } if($_REQUEST['state'] == $_SESSION['state']) { $token_url = "https://graph.facebook.com/oauth/access_token?" . "client_id=" . $app_id . "&amp;redirect_uri=" . urlencode($my_url) . "&amp;client_secret=" . $app_secret . "&amp;code=" . $code; $response = @file_get_contents($token_url); $params = null; parse_str($response, $params); $graph_url = "https://graph.facebook.com/me?access_token=" . $params['access_token']; $user = json_decode(file_get_contents($graph_url)); echo("Hello " . $user-&gt;name); } else { echo("The state does not match. You may be a victim of CSRF."); } ?&gt; </code></pre> <p>The output is only Hello, the user name does not show up!</p> <p>I think the problem is with the file_get_contents(), as echo-ing $response has no output, where as $token_url has the appropriate value.</p> <pre><code> $response = @file_get_contents($token_url); </code></pre> <ul> <li>PHP version = 5.2.9</li> <li>Error reporting is off, but including this in the code - error_reporting(E_ALL); gives no output.</li> </ul> <p><strong>UPDATE</strong> - So, I tried this after 6 months, and it worked. The only thing that has changed since then is my hosting. I was using HostBig before. <strong>Lesson</strong> - Don't depend on $1/month hosting services, they can't be trusted.</p>
