dedecmsHow to call related articles with the dreamweaver tag keyword?

DEDE's official dede:likearticle uses keywords entered in the article or keywords formed by automatic word segmentation to associate articles. However, sometimes the automatically generated keywords are not accurate, resulting in inaccurate association. , here we customize a class library file to accurately obtain related articles

Recommended learning: 梦Weavercms

You can use tags alone to call related articles, or Tag keyword can be used to call related articles (default tag takes precedence over keyword, you can sort by yourself)

Add a liketags.lib.php under \include\taglib\ and the code is as follows

<?php
if(!defined(&#39;DEDEINC&#39;)) exit(&#39;Request Error!&#39;);
function lib_liketags(&$ctag,&$refObj)
