设置从mysql数据库（使用php）读取信息的RSS提要（用于iTunes播客）

我有一个RSS源，我把iTunes链接到它上面，用来播客所有这些作品。然而，我正在尝试设置它，这样我就不必将每个播客数据硬编码到RSS提要中。因此，我的方法是使用一个podcast上传表单，将所有数据加载到一个mysql数据库中，然后使用php中的for循环将其读取到提要中。将表单中的数据输入数据库非常有效，连接和读取数据库也很有效。然而，当我尝试在RSS提要中实现这一点时，没有出现任何文章。以下是.rss文件的代码：

<?xml version="1.0" encoding="UTF-8" ?>
<rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0">

    mysql_connect($host, $username, $password) or die( "Unable to connect.");
    @mysql_select_db($database) or die( "Unable to select database.");

    $result = mysql_query("SELECT * FROM  `podcasts` WHERE 1 LIMIT 0 , 30");

    while ($row = mysql_fetch_array($result))

当然，主机、用户、密码和数据库都包含在实际代码中。按原样运行此代码时，不会显示任何错误。只有没有文章出现。任何帮助都将不胜感激。谢谢

我为此创建了一个小型开源库

您可以下载并学习如何使用它，但让我举个例子：

use iTunesPodcastFeed\Channel;
use iTunesPodcastFeed\FeedGenerator;
use iTunesPodcastFeed\Item;

require __DIR__ . '/vendor/autoload.php';

// SETUP CHANNEL

您确保Web服务器将.rss文件视为包含将被解析和执行的PHP代码的文件？对不起，我不完全确定您的意思。通常，Web服务器的配置是，只有以.PHP结尾的文件才会通过PHP解析器推送。您提到您的文件以.rss结尾。你确定你的web服务器评估了文件中的PHP脚本吗？如果是，那么检查你的PHP错误日志。好吧，我尝试了3种方式重写文件，使用了.PHP、.rss和.xml，并使用了适当的编码，但没有一种有效。如果服务器不允许这样做，.php也不会写rss吗？您确保您的Web服务器将您的.rss文件视为包含将被解析和执行的php代码的文件吗？对不起，我不完全明白你的意思。通常，Web服务器的配置是，只有以.php结尾的文件才能通过php解析器。您提到您的文件以.rss结尾。你确定你的web服务器评估了文件中的PHP脚本吗？如果是，那么检查你的PHP错误日志。好吧，我尝试了3种方式重写文件，使用了.PHP、.rss和.xml，并使用了适当的编码，但没有一种有效。如果服务器不允许，那么.php也不会写rss吗？
