求助[function.file-get-contents]: failed to open stream: HTTP request failed!

startci

使用file_get_contents抓取网页内容代码如下
$filename = $this->cache_dir.'rss_Parse_'.md5($this->feed_uri);
$rawFeed = file_get_contents($filename);
出现如下问题：
A PHP Error was encountered

Severity: Warning

Message: file_get_contents(http://feeds.arstechnica.com/arstechnica/index/) [function.file-get-contents]: failed to open stream:

=============================================================================

google或者baidu一下，好多这样的问题，解决的方法都是修改php.ini，把allow_url_fopen给启用，改成 allow_url_fopen = On

还得设置php.ini里面的user_agent，php默认的user_agent是PHP，我们把它改成Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)来模拟浏览器user_agent=”Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)”

============================================================================
按照如上进行配置，重新启动问题依旧，哪位遇到过同类问题怎么解决的，多谢！
