最近通过手机访问本地服务器时出现以下问题：
Access forbidden!
New XAMPP security concept:
Access to the requested directory is only available from the local network.
This setting can be configured in the file "httpd-xampp.conf".
If you think this is a server error, please contact the webmaster.
解决方法：
打开httpd-xampp.conf(/xampp/apache/conf/extra/httpd-xampp.conf)
#
# New XAMPP security concept
#
<LocationMatch "^/(?i:(?:xampp|security|licenses|phpmyadmin|webalizer|server-status|server-info))">
Order deny,allow
#Deny from all
Allow from 127.0.0.0/8
ErrorDocument 403 /error/HTTP_XAMPP_FORBIDDEN.html.var
</LocationMatch>
注：Deny from all注释掉，变成: #Deny from all
注：需要重启apache[/opt/lampp/lampp restartapache]
就可以远程登录xampp了，通过外网登陆本地xampp了。
--------------------------------------------------------------------------------
新版本可能是用下面的这个方法：
# Require local
ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
正解方法是注掉本地访问这行，如下：
#Require local
最后，重启启动xampp，OK了
xampp 访问出现New XAMPP security concept 解决办法
