PHP文件获取内容&字符串编码 [英] PHP File Get Contents & String Encoding

问题描述

检索css文件的内容：（ http://gizmodo.com/assets /stylesheets/app-ecbc6044c59319aab4c2a1e31380ef56.css ）

使用 mb_detect_encoding 检测到编码...

在浏览器中查看页面，看起来很好（可读），并声明 @charsetUTF-8 code>

尝试输出字符串，得到垃圾。
尝试将其保存到文件，有垃圾。

尝试将编码转换为ASCII，ISO-8859-1和HTML-ENTITIES。没有运气。

这里的任何想法如何确定为什么这个字符串是垃圾，以及如何解决它？

解决方案

  $ url ='http://gizmodo.com/assets/stylesheets/app-ecbc6044c59319aab4c2a1e31380ef56.css'; 
 
 $ ch = curl_init（）; 
 $ timeout = 5; 
 curl_setopt（$ ch，CURLOPT_URL，$ url）; 
 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，1）; 
 curl_setopt（$ ch，CURLOPT_CONNECTTIMEOUT，$ timeout）; 
 curl_setopt（$ ch，CURLOPT_ENCODING，gzip）; 
 $ data = curl_exec（$ ch）; 
 curl_close（$ ch）; 
 echo $ data; 
  

重要行是

  curl_setopt（$ ch，CURLOPT_ENCODING，gzip）; 
  

Retrieved the contents of a css file: (http://gizmodo.com/assets/stylesheets/app-ecbc6044c59319aab4c2a1e31380ef56.css)

Detected the encoding with mb_detect_encoding... says UTF-8.

Viewed the page in a browser, looks fine (readable), and declares @charset "UTF-8";

Tried to output the string, got garbage. Tried to save it to a file, got garbage.

Tried to convert the encoding to ASCII, ISO-8859-1, and HTML-ENTITIES. No luck.

Any ideas here how to determine why this string is garbage, and how to fix it?

解决方案

$url = 'http://gizmodo.com/assets/stylesheets/app-ecbc6044c59319aab4c2a1e31380ef56.css';

$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch,CURLOPT_ENCODING , "gzip");
$data = curl_exec($ch);
curl_close($ch);
echo $data;

Important line is

curl_setopt($ch,CURLOPT_ENCODING , "gzip");
