Question

过去几天我一直在努力弄清楚为什么我的代码在本地完美运行但在生产服务器上部署时失败了。

我的本地测试环境是10.7.2 Lion iMac上最新的MAMP。

基本上我需要从Artistdata.com获取某些XML RSS数据，以便将其插入到我正在处理的简单的PHP驱动的非CMS网站中。

<!DOCTYPE html>
<html>
<head>
<title>RSS FEED Parser</title>
</head>

<body>

<?php
    ini_set('display_errors',1);
    ini_set('display_startup_errors',1);
    error_reporting(-1);

    # RSS Feed parser #
    function getFeed($feed_url) {
        $content = file_get_contents($feed_url);
        $x = new SimpleXmlElement($content);

        foreach ($x->show as $showEntry) {
            echo '<div>';# date
                $newDate = new DateTime($showEntry->date);
                echo date_format($newDate, 'l, F j, Y');
            echo '</div>';# /date

            # further data fetching, totally unrelated
            # to the problem that I'm experiencing
        }
    }
?>

<!-- START FEED PARSING -->
<div id="feed-data">
    <?php getFeed('http://feeds.artistdata.com/xml.shows/artist/AR-30CA266E4BEDD78F/xml/future'); ?>
</div>
<!-- END FEED PARSING -->

</body>
</html>

我确信有更多人遇到过类似的问题，但我还没有找到可行的解决方案。

如果您有任何指示，我将非常感激。

问题已解决，我使用了错误的Feed，正确的是[{3}}

Answer 1

该XML看起来不像RSS。它是http://feeds.artistdata.com/_css/shows.xsd定义的特定格式。

错误消息都表示您获得的是HTML（2.0）页面而不是XML。我无法重现，我使用file_get_contents（）获取XML。

尝试输出HTML页面，也许还有更多信息。

echo file_get_contents('http://feeds.artistdata.com/xml.shows/artist/AR-30CA266E4BEDD78F/xml/future');

Artistdata.com RSS Feed解析在本地工作，但不在生产服务器上
