file_get_contents获取XML的奇怪问题
用
ini_set('user_agent','Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)'); // 这一句加不加结果都一样
$contents=file_get_contents($url);
获取一个XML文件，得到的结果是：

<?xml version="1.0" encoding="UTF-8"?><cities>
<city><cityid>2421</cityid><cityname>上海</cityname></city>
<city><cityid>2420</cityid><cityname>天津</cityname></city>
</cities>

而我用浏览器或其他工具取得的源码都是这样的：

<?xml version="1.0" encoding="UTF-8"?><cities>
<city><id>2421</id><name>涓婃捣</name></city>
<city><id>2420</id><name>澶╂触</name></city>
</cities>

为什么会这样呢？ 一个是cityid，另一个是id，一个是cityname，另一个是name

你的url是什么。。可以贴出来吧。

<?xml version="1.0" encoding="UTF-8"?><cities>
<city><cityid>2421</cityid><cityname>上海</cityname></city>
<city><cityid>2420</cityid><cityname>天津</cityname></city>
<city><cityid>2419</cityid><cityname>北京</cityname></city>
<city><cityid>2418</cityid><cityname>重庆</cityname></city>
<city><cityid>372</cityid><cityname>深圳</cityname></city>
<city><cityid>2422</cityid><cityname>广州</cityname></city>

浏览器或file_get_contents都是如下结果

<?xml version="1.0" encoding="UTF-8"?><cities>

<city><cityid>2421</cityid><cityname>上海</cityname></city>

<city><cityid>2420</cityid><cityname>天津</cityname></city>

<city><cityid>2419</cityid><cityname>北京</cityname></city>

<city><cityid>2418</cityid><cityname>重庆</cityname></city>
