刚接触php，麻烦各位帮忙看下错误
谢谢．
Warning: require(DIR_WS_TEMPLATEStemplate_default/common/html_header.php) [function.require]: failed to open stream: No such file or directory in E:\chinateamall\index.php on line 43Fatal error: require() [function.require]: Failed opening required 'DIR_WS_TEMPLATEStemplate_default/common/html_header.php' (include_path='.;C:\php5\pear') in E:\chinateamall\index.php on line 43
而include()函数只是在执行到这一条语句时才会把头文件内容包含进来。如果程序没运行到这里，那PHP是不会管它的。这就意味着，您在条件判定部分使用include时，它会完全按照您希望的那样工作。 还有，如果您用了require()函数，而您指定的头文件并不存在，那么程序将会停止运行并产生错误。如果您用了include()，程序会产生一个警告信息，但是会继续运行。
我是安装开源代码．
安装环境win2003+iis
不知道要注意什么？<?php

你先echo $template->get_template_dir('html_header.php',DIR_WS_TEMPLATE, $current_page_base,'common');看是什么，看html_header.php
在那个目录下吗
常量是怎么定义的。
比如你那个 DIR_WS_TEMPLATE
DIR_WS_MODULES
