WordPress提要中的内容包含垃圾社交图片-如何删除？ PHP字符串或Wordpress

Question

If you look at the content feed on http://minnesotatransplant.wordpress.com/feed/ for example - you'll see a pile of quite poor share and social images at the bottom of each item's content:encoded.

Does anyone know how to get rid of these or programmatically remove with PHP?

Answer 1

For anyone who's interested, I ended up doing...

                    $whereIsNaughtyString = strpos($contentwords, "<a rel=\"nofollow\"");
                    $contentTrimmed = substr($contentwords, 0, $whereIsNaughtyString);

Which got rid of all the stuff.
