不管是为了seo优化，或者方便加广告之类的，外链跳转，对于建站而言，有时候还是挺好用的。
新建一个go.php
在链接之前加：
https://bbs.zsxwz.com/go.php?url=
即可实现跳转。
<?php
$t_url=$_GET['url'];
if(!empty($t_url)) {
preg_match('/(http|https):\/\//',$t_url,$matches);
if($matches){
$url=$t_url;
$title='链接跳转中...';
} else {
preg_match('/\./i',$t_url,$matche);
if($matche){
$url='http://'.$t_url;
$title='链接跳转中...';
} else {
$url='https://bbs.zsxwz.com/';
$title='参数错误，正在返回首页...';
}
}
} else {
$title='参数缺失，正在返回首页...';
$url='https://bbs.zsxwz.com/';
}
?>

博客网站用的是wordpress，虽然加了go跳转，但没有用这个源码。
需要在functions.php，中加入：
add_filter('the_content','the_content_nofollow',999);
function the_content_nofollow($content)
{
preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$content,$matches);
if($matches){
foreach($matches[2] as $val){
if(strpos($val,'://')!==false && strpos($val,home_url())===false && !preg_match('/\.(jpg|jepg|png|ico|bmp|gif|tiff)/i',$val)){
$content=str_replace("href=\"$val\"", "href=\"".home_url()."/go/?url=$val\" ",$content);
}
}
}
return $content;
}
论坛就比较简单粗暴了，配合文件链接转超链接，直接加到了所有链接上了，比较方便的是，发帖不管你发链接是不是超链接，最后都是超链接。
