Answer 1

The easiest way is to consume your Wordpress RSS feed.

Download it using file_get_contents() or cURL for more control.

Parse it with simpleXML and output it.

You'll probably want to cache it somewhere... you could use APC user functions or PEAR::Cache_Lite .

Edit: the code would look something like this (you'd want more error checking and stuff - this is just to get you started):

$xmlText = file_get_contents('http://www.blabla.com/blog/feed/');

$xml = simplexml_load_string($xmlText);

foreach ($xml->item as $item)
{
    echo 'Blog Post: <a href="' . htmlentities((string)$item->link) . '">'
        . htmlentities((string)$item->title) . '</a>';

    echo '<p>' . (string)$item->description . '</p>';
}

Using WordPress best practices, you shouldn't be loading wp-blog-header.php, but rather wp-load.php, as it was specifically created for this purpose.

After this, use either the WP_Query object or get_posts() . An example of how to use WP_Query is available on The Loop page on the WordPress codex. Although using either of these doesn't matter if you use them from outside WordPress, there's less chance of something interfering, such as GET parameters.

For example, using WP_Query:

<?php
$my_query = new WP_Query('showposts=3');
while ($my_query->have_posts()): $my_query->the_post();
?>
<h1><a href="<?php the_permalink() ?>"><?php the_title() ?></a></h1>
<?php endwhile; ?>

Or, using get_posts():

<?php
global $post;
$posts = get_posts('showposts=3');
foreach($posts as $post) :
?>
<h1><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h1>
<?php endforeach; ?>

Hope this helps! :)

works great!

<?php
// Include Wordpress 
define('WP_USE_THEMES', false);
require('blog/wp-blog-header.php');
query_posts('showposts=3');


?>      
<?php while (have_posts()): the_post(); ?>
<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<?php endwhile; ?>

我想最简单的解决方案是直接从数据库中获取帖子。
