    <p>You should start with <a href="http://developers.facebook.com/docs/reference/php/">Facebook PHP SDK</a> , the key is to understand server-side login flow, as explained <a href="http://developers.facebook.com/docs/concepts/login/login-architecture/">here</a>, you can use this example as a start:</p> <pre><code>require 'facebook.php'; $facebook = new Facebook(array( 'appId' =&gt; 'YOUR_APP_ID', 'secret' =&gt; 'YOU_APP_SECRET', )); // Get User ID $user = $facebook-&gt;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-&gt;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-&gt;getLogoutUrl(); } else { $loginUrl = $facebook-&gt;getLoginUrl(array("scope" =&gt; "user_photos")); } ?&gt; &lt;!doctype html&gt; &lt;html xmlns:fb="http://www.facebook.com/2008/fbml"&gt; &lt;head&gt; &lt;title&gt;&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;?php if ($user): ?&gt; &lt;a href="&lt;?php echo $logoutUrl; ?&gt;"&gt;Logout&lt;/a&gt; &lt;?php else: ?&gt; &lt;div&gt; &lt;a href="&lt;?php echo $loginUrl; ?&gt;"&gt;Login with Facebook&lt;/a&gt; &lt;/div&gt; &lt;?php endif ?&gt; &lt;h3&gt;PHP Session&lt;/h3&gt; &lt;pre&gt;&lt;?php print_r($_SESSION); ?&gt;&lt;/pre&gt; &lt;?php if ($user): ?&gt; &lt;h3&gt;You&lt;/h3&gt; &lt;img src="https://graph.facebook.com/&lt;?php echo $user; ?&gt;/picture"&gt; &lt;h3&gt;Your User Object (/me)&lt;/h3&gt; &lt;pre&gt;&lt;?php print_r($user_profile); ?&gt;&lt;/pre&gt; &lt;?php else: ?&gt; &lt;strong&gt;&lt;em&gt;You are not Connected.&lt;/em&gt;&lt;/strong&gt; &lt;?php endif ?&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

    1. COI did look there. I need an actual example, there is quite a lot of theory, but i'd love to see some code. For example the code to request access to user photos. Easy stuff, but **an example**

    2. COif you want users photos you need to request `array("scope" => "user_photos")` then redirect the user to `$loginUrl`, at this point he will login to facebook and or give your application permissions to acces the images he is tagged in (make sure you specify return url to your application hardcoded or in application settings, then you should be able to run an api command to fetch photos.

    3. COThe `$loginUrl` only shows what information your app tries to access, but doesn't actually request the access, as far as I know. I may be mistaken, however. The difference is quite significant.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
