copied!<p>If you already use SimplePie then you can use its <a href="http://simplepie.org/wiki/faq/how_does_simplepie_s_caching_http_conditional_get_system_work" rel="nofollow noreferrer">caching mechanism</a> to have the feed data cached. </p> <p>To combine the articles from internal and external sources create a data structure with all articles. This can be an array of all items sorted by publication timestamp. Then from this array choose the articles for a certain page number.</p> <p>Here's some code to create a combined array of posts. This should give you a idea of the steps involved. The Post class represents a post. The internal and external posts are converted to a Post and stored in the array <strong>$posts</strong>. This array is sorted by timestamp and at the end all posts are echoed.</p> <p><strong>$internalPosts</strong> must contain the posts form your system and <strong>$feedUrls</strong> the URL's of the external feeds. Since I don't know the structure of the internal posts you must adapt the part where internal posts are converted to generic posts.</p> <pre><code>$internalPosts = array(); $feedUrls = array(); include_once 'simplepie.inc'; class Post { public $title; public $link; public $description; public $publishedAt; public function __construct($title, $link, $description, $publishedAt) { $this->title = $title; $this->link = $link; $this->description = $description; $this->publishedAt = $publishedAt; } } $posts = array(); // Convert internal posts to generic post. foreach($internalPosts as $item){ $posts[] = new Post($item->title, $item->link, $item->description, $item->publishedAt); } // Retrieve feeds and add posts. $feed = new SimplePie(); foreach($feedUrls as $url){ $feed->set_feed_url($url); $feed->init(); foreach ($feed->get_items() as $item) { $posts[] = new Post($item->get_title(), $item->get_link(), $item->get_description(), $item->get_date('U')); } } // Sort function. function byPublicationTimestamp($itemA, $itemB){ return ($itemB->publishedAt - $itemA->publishedAt); } usort($posts, 'byPublicationTimestamp'); foreach($posts as $post){ echo "<p><a href='$post->link'>$post->title</a><br/>" . date('l, j F Y', $post->publishedAt) . " - $post->description</p>"; } </code></pre> <p>For improved performance consider storing the combined articles separately and build the pages from this data. Then you need to update this combined data anytime a new article is published internally or the cached version of an external feed has been refreshed.</p> <p>If you need to publish the external content shortly after it's published on the original site then I would contact those sites to see if it's possible to get a notification of updates instead of waiting for the cached version to expire.</p> <p>EDIT: added sample code.</p>
