原本的tag链接类似于：

http://www.zzblo.com/tags.php?/织梦/

http://www.zzblo.com/tags.php?/MySQL/

但是从seo的角度来看，我希望 吧链接修改为

http://www.zzblo.com/tags/MySQL/

http://www.zzblo.com/tags/织梦/ 。

修改了两个文件:

【1】 、/include/taglib/tag.lib.php

大概在87行将

$row['link'] = $cfg_cmsurl."/tags.php?/".urlencode($row['keyword'])."/";

修改为

$row['link'] = $cfg_cmsurl."/tags/".urlencode($row['keyword'])."/";

【2】、/include/arc.taglist.class.php

大概在457行将

$purl = $this->GetCurUrl(); $purl .= "?/".urlencode($this->Tag);

将修改为:

$purl = "/tags/".urlencode($this->Tag);

然后就是设置伪静态：
apache主机：

RewriteRule ^tags.html$ tags.php RewriteRule ^tags/(.*)/$ tags.php?/$1 RewriteRule ^tags/(.*)/([0-9]+)/$ tags.php?/$1/$2/

Nginx主机：

rewrite "^/tags.html$" /tags.php last; rewrite "^/tags/(.*)/$" /tags.php?/$1/ last; rewrite "^/tags/(.*)/([0-9]+)/$" /tags.php?/$1/$2/ last;
