PHP中的UTF-8编码xml [英] UTF-8 encoding xml in PHP

问题描述

我正在尝试使用PHP输出XML，当我在Firefox中查看页面源代码时，一切似乎都很好.但是，页面本身无法正确显示.

I'm trying to output XML using PHP, and when I look at the page source in Firefox everything seems fine. However, the page itself doesn't display properly.

在Firefox中，当它显示正确格式的XML时，通常会在页面顶部显示此信息:

In Firefox, it usually says this at the top of the page when it's showing correctly formatted XML:

This XML file does not appear to have any style information associated with it. The document tree is shown below.

..然后显示xml树.

..and then it shows the xml tree.

但是，我只是在xml标记中获得了字符，而没有树.

However, I just get the characters within the xml tags, and no tree.

我能看到的唯一区别是我的页面被编码为Western ISO-8859-1，而正确显示的XML被编码为Unicode UTF-8.那么如何将页面输出为Unicode UTF8?

The only difference I can see is that my page is encoded as Western ISO-8859-1 and the correctly displayed XML is encoded as Unicode UTF-8. So how would I output my page as Unicode UTF8?

我已经尝试过了，但这没什么区别:

I've tried this but it doesn't make any difference:

echo utf8_encode($xmlstring);

推荐答案

请确保您发送的XML具有适当的内容类型和编码，例如

Make sure you send the XML with an appropriate content-type and encoding, e.g.

<?php header("Content-Type: application/xml; charset=utf-8"); ?>

还要检查XML序言是否包含正确的编码，例如

Also check that the XML prolog contains the proper encoding, e.g.

<?xml version="1.0" encoding="UTF-8"?>

有关样式信息的消息是指缺少的处理指令，例如

The message about the style information refers to a missing processing instruction, e.g.

<?xml-stylesheet type="text/xsl" href="someting"?>

，它将告诉浏览器如何设置输出的样式/格式.如果您只想显示原始XML，则不一定需要.

which would tell the browser how to style/format the output. It is not necessarily needed if you just want to display the raw XML.
