SimpleXML-I/O警告:无法加载外部实体 [英] SimpleXML - I/O warning : failed to load external entity

问题描述

我正在尝试创建一个小型应用程序，该应用程序将简单地读取RSS提要，然后在页面上布置信息.

I'm trying to create a small application that will simply read an RSS feed and then layout the info on the page.

我发现的所有说明都使这看起来很简单，但是由于某种原因它无法正常工作.我有以下

All the instructions I find make this seem simplistic but for some reason it just isn't working. I have the following

include_once(ABSPATH.WPINC.'/rss.php');
$feed = file_get_contents('http://feeds.bbci.co.uk/sport/0/football/rss.xml?edition=int');
$items = simplexml_load_file($feed);

就这样，然后它在第三行中断并出现以下错误

That's it, it then breaks on the third line with the following error

Error: [2] simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "<?xml version="1.0" encoding="UTF-8"?> <?xm
The rest of the XML file is shown.

我已在我的设置中启用了allow_url_fopen和allow_url_include，但仍然没有执行任何操作. 我尝试了多个提要，但最终都得到了相同的结果?

I have turned on allow_url_fopen and allow_url_include in my settings but still nothing. I've tried multiple feeds that all end up with the same result?

我要在这里生气

推荐答案

simplexml_load_file()将 XML文件(磁盘上的文件或URL)解释为对象. $feed中的内容是一个字符串.

simplexml_load_file() interprets an XML file (either a file on your disk or a URL) into an object. What you have in $feed is a string.

您有两个选择:

• 使用file_get_contents()获取XML提要作为字符串，并使用e

• Use file_get_contents() to get the XML feed as a string, and use e simplexml_load_string():

$feed = file_get_contents('...');
$items = simplexml_load_string($feed);

使用 simplexml_load_file()直接加载XML feed :

Load the XML feed directly using simplexml_load_file():

$items = simplexml_load_file('...');
