php - 简单的 RSS 提要

Question

我正在尝试制作一个简单的 rss 提要，但问题是当我运行文件时说你想打开 rss.php ...

这是代码，也许我做错了什么？我把它放在这种格式中只是为了看看它是否有效。

<?php
header('Content-Type: application/rss+xml; charset=utf-8');
?>
&#60;?xml version='1.0' encoding='ISO-8859-1'?&#62;
<rss version='2.0'>
<channel>
<title>feed title</title>
<description>this is my example</description>

Answer 1

你应该输出真实的<?xml version='1.0' encoding='ISO-8859-1'?> ，不是实体化版本。由于 php 自身的问题 <? , echo它在标题之后:

<?php
//header('Content-Type: application/xml');
header('Content-Type: application/rss+xml; charset=utf-8');
echo '<?xml version="1.0" encoding="utf-8"?>';
?>
<rss version='2.0'>
