1。根目录下.htaccess（规则适用iis，其他nginx、apache还要稍做修改）
RewriteEngine on
RewriteRule f(\d+)_(.*)_(.*)$ /thread.php?fid=$1&page=$2&type=$3 [L]
RewriteRule f(\d+)_(.*)$ /thread.php?fid=$1&page=$2 [L]
RewriteRule f(\d+)$      /thread.php?fid=$1 [L]
RewriteRule (\d+)_(.*)_(.*)_(.*).html$ /read.php?tid=$1&page=$2&fpage=$3&uid=$4 [L]
RewriteRule (\d+)_(.*)_(.*).html$  /read.php?tid=$1&page=$2&fpage=$3 [L]
RewriteRule (\d+)_(.*).html$   /read.php?tid=$1&page=$2 [L]
RewriteRule (\d+).html   /read.php?tid=$1 [L]
RewriteRule ^(.*)-htm-(.*)$ $1.php?$2 [L]
RewriteRule /simple/([a-z0-9\_]+)\.html$ /simple/index\.php\?$1 [L]
2、在require/common.php
找到
function urlRewrite($url) {
换成：
