simplexml_load_file仅适用于实时网站

I have recently put my website online and found simplexml_load_file problem. It works perfectly on local server (MAMP) but not live on the website. Code is as below:

我最近把我的网站放在网上,发现simplexml_load_file问题。它在本地服务器(MAMP)上完美运行,但不在网站上。代码如下:

<?
$source = simplexml_load_file('http://domainname.com/file.xml') or die("Something is wrong");
echo $source->Result;
?>

The above code displays following message on live website: "

以上代码在实时网站上显示以下消息:“

Something is wrong

出了点问题

And same code displays following message on local server MAMP:

并且相同的代码在本地服务器MAMP上显示以下消息:

Success

And file.xml is:

而file.xml是:

<?xml version="1.0"?>
<!DOCTYPE ValidateUser>
<ValidateUser>
  <Customer>john</Customer>
  <Result>Success</Result>
</ValidateUser>

Thanks in advance.

提前致谢。

It sounds like your hosting provider has disabled PHP's ability to open URL's as files.

听起来您的托管服务提供商已禁用PHP打开URL作为文件的能力。

Run the following snippit of code on your server. If the result is "0", then this feature has been disabled.

在您的服务器上运行以下snippit代码。如果结果为“0”,则表示此功能已被禁用。

<?php var_dump(ini_get('allow_url_fopen')); ?>

If its disabled you might need to use something like CURL to fetch the XML file before processing it. You could then use simplexml_load_string() instead of simplexml_load_file()

如果禁用它,您可能需要使用CURL之类的东西来处理XML文件。然后,您可以使用simplexml_load_string()而不是simplexml_load_file()

Here is an example of how to use CURL:

以下是如何使用CURL的示例:

If CURL is also not available you will have to discuss alternatives with your hosting provider.

如果CURL也不可用,您将不得不与您的托管服务提供商讨论替代方案。

So, using the code from the link above, you could do something like this:

因此,使用上面链接中的代码,您可以执行以下操作:

/* gets the data from a URL */
function get_data($url) {
    $ch = curl_init();
    $timeout = 5;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

$returned_content = get_data('http://davidwalsh.name');

$source = simplexml_load_string($returned_content) or die("Something is wrong");
echo $source->Result;
