Redirect jumps to external links of the website

In the comment function of Emlog, the commenter can fill in his or her website address. But many times we don’t want our website to have too many cluttered external links. Of course, we can add the nofollow attribute to the link. That is to say, the original link code is

<a href="http://www.php.cn">一路上</a>

When we add the rel="nofollow" attribute to this link, we tell the search engine not to pass the weight of this link address. It looks like:

<a href="http://www.php.cn" rel="nofollow">一路上</a>

And here, what I shared with you along the way is to redirect the external link address. That is, if the external link address is http://www.php.cn, through redirection, it becomes http://your website address/go.php?url=http://www.php.cn and it is still accessed Target website http://www.php.cn

First download the go.zip file, extract the go.php file and upload it to the root directory of your website, and then add http://www.php.cn in go.php Replace with your website address. Finally, you only need to replace the link address you want to convert from

<a href="&#39;.$comment[&#39;url&#39;].&#39;" target="_blank">
