开始的时候我是用http://www.landui.com/test.php进行的测试，没有发现问题，后来要在内网测试一下就要用IP地址进行那个访问了，如：http://www.landui.com/test.php，就出现了这个问题。
后来咨询了一下朋友（php高手），说修改一下php的配置文件httpd.conf。
在原有的位置文件中找到配置节
<Directory />
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all
    Satisfy all
</Directory>
修改成
<Directory />
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
#    Deny from all
    Allow from all
#允许所有访问
    Satisfy all
</Directory>
 
还有
 
<Directory "D:/Wamp5/www">
    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesnt give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://www.landui.com/docs/2.2/mod/core.html#options
    # for more information.
    #
    Options Indexes FollowSymLinks
    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   Options FileInfo AuthConfig Limit
    #
    AllowOverride all
    #
    # Controls who can get stuff from this server.
    #
#   onlineoffline tag - dont remove
    Order Deny,Allow
    Deny from all
    Allow from 127.0.0.1
</Directory>
修改成

</Directory>
然后保存，重启服务，在访问就解决了这个问题。
