copied!<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->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&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 = $this->getXMLFeeds($feed); return $getFeed->xpath('channel/item/title'); } } $feeds = new ForumFeed(); </code></pre> <p>However when trying to <code>echo $feeds->formatFeeds('all');</code> it doesn't return anything. The results is blank.</p> <p>What am I doing wrong?</p> <p><code>var_dump($feeds->formatFeeds('all'));</code> returns</p> <pre><code>array(3) { [0]=> object(SimpleXMLElement)#3 (0) { } [1]=> object(SimpleXMLElement)#4 (0) { } [2]=> object(SimpleXMLElement)#5 (0) { } } </code></pre>
