问题描述

我想使用php获取任何网页的所有元信息，例如描述，标题，关键字等.

I want to get all the meta information like description, title, keyword etc of any web page using php.

我正在使用get_meta_tags php函数，但显示警告.我在下面粘贴了错误.

I am using get_meta_tags php function but its displaying warning. I have paste the error below.

警告:file_get_contents()[function.file-get-contents]:php_network_getaddresses:getaddrinfo失败:此类主机未知.在文件名中...

我如何获取网页上的所有图像?

And how could i get all images on the web page?

谢谢.

推荐答案

"getaddrinfo失败"表明您的Web服务器的dns客户端配置不正确.因此php无法将"google.com"解析为实际的IP地址.

"getaddrinfo failed" suggests that your webserver's dns client isn't configured properly. Thererfore php cannot resolve "google.com" to an actual ip address.
