RSS 提要和 cdata 的问题 [英] problem with rss feed and cdata

问题描述

我的 rss 提要有问题.

I have a problem with an rss feed.

当我做

标题在提要中显示得很好

The title appears nicely in the feed

但是当我这样做的时候$title = "这是一个倾斜";

But when i ddo $title = "this is a tilte";

<title><![CDATA['$title']]></title>

标题根本没有出现.

还是不行.我动态生成我的 RSS 提要，它看起来像这样:

It still doesn't work. I generate my rss feed dynamicly and it looks like this:

$item_template="
      <item>
         <title>[[title]]</title>
         <link>[[link]]</link>
         <description><![CDATA[[[description]]]]></description>
         <pubDate>[[date]]</pubDate>
      </item>
      ";

并在循环中:

$s.=str_replace(
array("[[title]]","[[link]]","[[description]]","[[date]]"),
array(htmlentities($row["title"]),$url,$description,$date),
$item_template);

问题特别在于标题有欧元符号时.然后它显示在我的 rss 验证器中，例如:

The problem is specifically when the title has a euro sign. Then it shows up in my rss validator like:

Â\x80

<小时>

更多详细信息:

好的，过去几天我一直在为此苦苦挣扎，但找不到解决方案.所以我将开始赏金.以下是更多信息:

Ok I have been struggeling with this for the last few days and I can't find a solution. So I will start a bounty. Here is more information:

• Feed 中的信息存储在 latin 1 数据库中(我管理)
• 当数据库中有欧元符号时就会出现问题.无论是 € 还是 €
• 欧元符号有时看起来像奇怪的字符或像 \x80
• 我尝试在提要方面解决问题，而不是在读者方面.
• 完整代码可以在这里找到:codedump
• 下一步:有时当欧元符号无法解析时，项目(标题或描述)显示为空.因此，如果您在浏览器中显示提要时查看源代码，您会发现 <title></title>

如果需要更多信息，请询问.

If there is more information needed please ask.

推荐答案

问题是你输出的代码；改变

The problem is your outputting code; change

echo '<title><![CDATA[$title]]></title>';

到

echo '<title><![CDATA[' . $title . ']]></title>';

作为旁注，请注意以下事项:不要用后续问题回答您自己的问题，而是编辑原始问题.不要无缘无故地使用正则表达式.不要猜测.

As a side note, please mind the following: Do not answer your own question with a follow-up, but edit the original one. Do not use regexps for no good reason. Do not guess.

相反，做你一直以来应该做的事情:将标题包裹在 htmlentitites 并完成，如:

Instead, do what you should have done all along: Wrap the title in htmlentitites and be done, as in:

echo '<title>' . htmlentities($title, ENT_NOQUOTES, [encoding]) . '</title>';

将 [encoding] 替换为您正在使用的字符编码.最有可能的是UTF-8".这是必要的，因为 php(<6) 默认使用 ISO-8859-1 并且没有办法表达例如该编码中的欧元符号.如需更多信息，请参阅此精心编写的介绍.

Replace [encoding] with the character encoding you are using. Most likely, this is 'UTF-8'. This is necessary because php(<6) uses ISO-8859-1 by default and there is no way to express e.g. the Euro sign in that encoding. For further information, please refer to this well-written introduction.

我还建议您阅读有关 XML 的内容.从第二章开始.

I also suggest you read about XML. Start with the second chapter.
