    <p>So I got a simple function that works, but I'm trying to evolve my experince wtih OOP and try to make sure I can use my code without having to edit everything.</p> <p>Here is my simple function </p> <pre><code>$xmlfeed = file_get_contents('/forum/syndication.php?limit=3'); $xml = new SimpleXMLElement($xmlfeed); $result = $xml-&gt;xpath('channel/item/title'); while(list( , $node) = each($result)) { echo $node; } </code></pre> <p>Now so far I got to this point:</p> <pre><code>class ForumFeed { private function getXMLFeeds($feed = 'all'){ /* Fetch the XML feeds */ $globalFeedXML = file_get_contents('/forum/syndication.php?limit=3'); $newsFeedXML = file_get_contents('/forum/syndication.php?fid=4&amp;limit=3'); /* Turn feed strings into actual objects */ $globalFeed = new SimpleXMLElement($globalFeedXML); $newsFeed = new SimpleXMLElement($newsFeedXML); /* Return requested feed */ if ($feed == 'news') { return $newsFeed; } else if ($feed == 'all') { return $globalFeed; } else { return false; } } public function formatFeeds($feed) { /* Format Feeds for displayable content.. For now we're only interested in the titles of each feed */ $getFeed = $this-&gt;getXMLFeeds($feed); return $getFeed-&gt;xpath('channel/item/title'); } } $feeds = new ForumFeed(); </code></pre> <p>However when trying to <code>echo $feeds-&gt;formatFeeds('all');</code> it doesn't return anything. The results is blank.</p> <p>What am I doing wrong?</p> <p><code>var_dump($feeds-&gt;formatFeeds('all'));</code> returns</p> <pre><code>array(3) { [0]=&gt; object(SimpleXMLElement)#3 (0) { } [1]=&gt; object(SimpleXMLElement)#4 (0) { } [2]=&gt; object(SimpleXMLElement)#5 (0) { } } </code></pre>

    3. COYou try to echo an array, that normally gives you `"Array"` (as string). See as well: http://php.net/language.types.string#language.types.string.casting - Also try to isolate your problem. It's never the whole script. So put your script aside for a moment, and create a new one just for the question you want to ask here with as little code as necessary to demonstrate the issue. Also try to understand your own, what happens and why it happens.

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.
