php提示Warning: file_get_contents(): couldn’t resolve

 　　今天在使用一个Caiji功能的使用，突然间出现“

　　Warning: file_get_contents() [function.file-get-contents]: couldn't resolve host name in ……

　　而本地测试却没有问题，从网上查了一些资料，发现是dns的问题。下面是解决方法：

　　用ssh连接linux vps， 修改vps主机的dns。

　　vi /etc/resolv.conf

　　里面的内容直接修改成：

　　nameserver 114.114.114.114

　　nameserver 8.8.8.8

　　保存即可，不用重启。

　　再次测试，OK!
