早上好，请问关于php绝对路径的问题
朋友们早，新的一天阳光毒辣啊。
小弟有一个问题请教。
define('HOST','http://'.$_SERVER['HTTP_HOST'].'/');
我想在本地和服务器都是用绝对路径，所以定义了上面那个。
在服务器上是没问题的。
但是在本地比如说我的是http://localhost/csdn/
但是本地echo HOST;出来的只是http://localhost/
请问该怎么写才能达到在服务器上和本地是一样的呢？也就是在本地显示http://localhost/lcsdn/这样的
回复讨论(解决方案)
把你的程序放在根目录下，不放在lcsdn文件夹下
也就是你的程序要和lcsdn属于同一层下

我的有几个站，本地的都放在d:/website/下面
如
d:/website/csdn/
d:/website/baidu/
我是放在对应的csdn或baidu文件夹下面了。
设置成虚拟主机
或通过 url重写指派网站的根
其实写全 url 的做法是不可取的

试试看
$_SERVER['HTTP_HOST'] 本来就是获取域名或主机地址
在本地的话，你通过apache的httpd.conf设置下虚拟主机也能解决问题
