How to truncate wp_rss

Question

weiß jemand die beste Möglichkeit, einen RSS-Feed mit wp_rss zu kürzen? Ich habe versucht zu googeln und konnte nichts finden. Jede Hilfe wäre willkommen!

Hier ist mein Code:

<?php 
include_once(ABSPATH . WPINC . '/rss.php'); 
$feed = 'http://miletich2.blogspot.co.uk/feed/'; 
$rss = fetch_feed($feed); 
?> 
<div class="container"> 
<div class="right"> 
<div class="rss-container"> 
<div class="rss-heading"> 
<?php 
$title = "Clashing With Life"; 
$description = 'This is a blog written by an autistic person for other autistic people about <br>some of the biggest issues in life, whether deplorable or marvelous.'; 
echo '<h3 class="text-center">' . $title . '</h3>'; 
echo '<p class="">' . $description . '</p>'; 
?> 
</div> 
<div class="text-center"> 
<?php 
if (!is_wp_error($rss)) : 
     $maxitems = $rss->get_item_quantity(3); 
    $rss_items = $rss->get_items(0, $maxitems); 
    if ($rss_items): 
     echo "<ul>\n"; 
     foreach ($rss_items as $item) : 
      //instead of a bunch of string concatenation or echoes, I prefer the terseness of printf 
      //(http://php.net/manual/en/function.printf.php) 

      printf('<div class=""><li><a href="%s">%s</a><p>%s</p><p>%s</p></li></div>',$item->get_permalink(),$item->get_title(),$item->get_date(get_option('date_format')),$item->get_description()); 
     '<hr>'; 
     endforeach; 
     echo "</ul>\n"; 
    endif; 
endif; 
?> 
</div> 
</div> 
</div> 
</div>

Sie wp_trim_words() verwenden können und wp_strip_all_tags()

Beispiel:

if (!is_wp_error($rss)) : 
    $maxitems = $rss->get_item_quantity(3); 
    $rss_items = $rss->get_items(0, $maxitems); 
    if ($rss_items): 
     foreach ($rss_items as $item) : 
      $item_title  = esc_attr($item->get_title()); 
      $item_permalink = esc_url($item->get_permalink()); 
      $item_post_date = $item->get_date(get_option('date_format')); 
      $item_excerpt = wp_trim_words(wp_strip_all_tags($item->get_description(), true), 55); 
      echo sprintf('<div class=""><a href="%s">%s</a><p>%s</p><p>%s</p></div>', $item_permalink, $item_title, $item_post_date, $item_excerpt); 
     endforeach; 
    endif; 
endif; 

Btw, include_once(ABSPATH . WPINC . '/rss.php'); unnötig ist. Sie sollten es entfernen.
