apache的错误日志老出现：
Warning: DocumentRoot [D:/webserver/apache2.2/docs/dummy-host2.localhost] does not exist
httpd.exe: Could not reliably determine the server's fully qualified domain name, using 192.168.1.169 for ServerName
Warning: DocumentRoot [D:/webserver/apache2.2/docs/dummy-host2.localhost] does not exist
httpd.exe: Could not reliably determine the server's fully qualified domain name, using 192.168.1.169 for ServerName
Failed loading D:/webserver/php5/ext/php_xdebug-2.1.2-5.2-vc6-nts.dll
导致xdebug老是不能加载，试了好多版本的，可是都不行，最后搜到一个解决方案：
把phpinfo()的信息拷贝到xdebug官网的一个测试页面： http://www.xdebug.org/find-binary.php ，让官网来测试我的环境找到合适的版本，这确实不错哦
虽然不是Warning: DocumentRoot [D:/webserver/apache2.2/docs/dummy-host2.localhost] does not exist，这个问题，
但这个警告还是不太清楚！
