请问：failed to open stream: Permission denied in Unknown on line 0

请教：failed to open stream: Permission denied in Unknown on line 0

<br />Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0<br /><br />Warning: Unknown: Failed opening 'D:/okbuy/index.php' for inclusion (include_path='.;C:\php5\pear') in Unknown on line 0<br />

公司的电脑用的是 win7,家里面的电脑用 winxp,相同的代码拷贝到家里面的电脑，就提示上面的问题，如果把  index.php  只

 echo phpinfo(); 

不会有错，写上实际的代码就有错，请教各位大侠，这个问题怎么处理。

php include stream path html
------解决方案--------------------
被包含的文件没有权限操作？

你是否在你本地的电脑启用了APC？ 或者是其他PECL扩展库？
之前在win上遇到过类似的问题，最终无果而终
