从eclipse发布php文件到apache htdocs

How can publish from Eclipse to Apache's htdocs on local?, I remember I was able to do this long time ago but forgot the process. Is there like a setting that i can do in Eclipse so that it publishes any file i add to the htdocs or if I modify it?. Initially I copied the whole folder from workspace and put it in htdocs.. and it runs but now any change I make in eclipse does not get publish. How can publish from Eclipse to Apache's htdocs
