PHP Fatal error: Unknown: Failed opening required

问题描述：apache日志中突然报如下错误：

[Wed Nov 05 15:24:06 2014] [error] [client xxx.xxx.xxx.xxx] PHP Warning:  Unknown: failed to open stream: Operation not permitted in Unknown on line 0

[Wed Nov 05 15:24:06 2014] [error] [client xxx.xxx.xxx.xxx] PHP Fatal error:  Unknown: Failed opening required '/webpath/webcode/index.php' (include_path='.:/usr/share/pear:/usr/share/php') in Unknown on line 0

问题原因：php的配置文件php.ini中open_basedir被打开并修改

解决方法：

1、将open_basedir注释掉

2、在open_basedir中添加webpath
