}</pre></div><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";">
把上边的代码加入到首页index.php中</p><div class="jb51code" style="margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";"><pre class="brush:php;toolbar:false;">if(!file_exists(dirname(__FILE__).'/data/common.inc.php'))</pre></div><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";">
的上边。</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";">
但请注意了：如果你的默认首页index.html排在了index.php上面，那么以上方法就不管用了。</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";">
