define("DOC_HOME_PATH", "what goes here")

I want to define 3 constants DOC_HOME_PATH IMG_HOME_PATH CTL_HOME_PATH So that I can just do this <img src="<? echo IMG_HOME_PATH ?>stuff/image.jpg"> <a href="<? echo DOC_HOME_PATH ?>stuff/index.jsp">Click Here</a> <form action="<? echo CTL_HOME_PATH ?>stuff/process_order.php"> **do I need to echo? **not everything goes to "stuff" Right now I have define ("DOC_HOME_PATH", "d:/is/projects/killerspin/web/store/"); define ("IMG_HOME_PATH", "d:/is/projects/killerspin/web/images/"); define ("CTL_HOME_PATH", "d:/is/projects/killerspin/web/control/"); This works fine for displaying images but not for form submission or links. I have also tried this define ("DOC_HOME_PATH", "http://localhost/killerspin/web/store/"); define ("IMG_HOME_PATH", "http://localhost/killerspin/web/images/"); define ("CTL_HOME_PATH", "http://localhost/killerspin/web/control/"); doesn't work. I have also tried a few other ways, but to no avail. Right now the config is Apache 2.0.43, PHP 4.3.0, Win Xp Pro, and an Access DB. For production this will be running on a windows server so I would also need to know to set up the same var for this enviroment. Thanks in advance ---> Jonathan
