什么会导致DOMDocument.load无法从可访问的URL加载XML?

$doc = new DOMDocument();
if ($doc->load('http://foo.com/bar.xml')) {
  // good
} else {
  // wtf happened?
}

I can wget http://foo.com/bar.xml from the location where the PHP code is running, so I know the URL is accessible. I'm thinking it must be something other than an HTTP error.

I'm not sure what else could be causing the failure. Maybe a parsing issue? The XML appears to be valid (and passes W3C's validation test). As far as I can tell from the documentation, there's no way to determine why the load failure occurred.

Here's the XML:

 <response> 
  <version>8</version> 
  <minversion>1</minversion> 
  <url>api.asp?</url> 
 </response>

    I finally narrowed it down to a PHP configuration setting called allow_url_fopen, which was set to Off on the server running the script.

    I modified the php.ini file to enable this setting:

    allow_url_fopen = On
    

    And now DOMDocument.load can load XML from a remote URL.

    WARNING: apparently there are some security issues with keeping this setting on permanently.
