当局域网或外网访问xampp时，报如下错误时：
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”.
解决办法：
打开httpd-xampp.conf(/xampp/apache/conf/extra/httpd-xampp.conf)
找到以下内容：
版本内容一：
=======================================================================================================================
# New XAMPP security concept
#
Order deny,allow
Deny from all
Allow from ::1 127.0.0.0/8
fc00::/7 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16
81.196.40.94/32
ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
将Deny from all这一行注释掉，即
#Deny from all
=====================================================================
版本内容二：
=======================================================================================================
# New XAMPP security concept
#
Require local
ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
将Require local这一行注释掉，即
#Require local
