PHP搞个echo XML都折磨疯哥了
$conn=mysql_connect("localhost","root","root");
if(!$conn){
echo "OK";
}
$query='SELECT * FROM rcuset order by no desc';
$result=mysql_db_query("test",$query);
echo "";
while($row = mysql_fetch_object($result)) {
  echo "no>";
  echo "".$row->ch."";
  echo "".$row->f."";
  echo "
";
}
echo "
";
mysql_free_result($result);
mysql_close();
?>
刚开始可以输出字符串。但是查看源文件是XML格式的
加了行header("Content-type:text/xml");
就提示
-----------------------
无法显示 XML 页。 
使用 XSL 样式表无法查看 XML 输入。请更正错误然后单击 刷新按钮,或以后重试。 


--------------------------------------------

XML 文档只能有一个顶层元素。处理资源 'http://localhost/getXML.php' 时出错。第 2 行,位置: 2 

Warning: Cannot modify header information - headers already sent by (output started at C:\AppServ\www\ge...
------------------------
后来去掉了那个header("Content-type:text/xml");
结果反而又没字符串了

纠结的哥蛋疼哦

------解决方案--------------------
因为你输出的是xml, 查看源文件就能看到了。
------解决方案--------------------
是你加上 header("Content-type:text/xml"); 这后出现的 

因为 在header前不能有什么的输出。
出这个错误是因为 header('Content-Type:text/html;');发送头之前不能有任何输出,空格也不行,你需要将header(...)之前的空格去掉,或者其他输出的东西去掉,或者把header 直接放到 程序最上面,保证没有什么输出。echo print_r var_dump 之类的输出形式
------解决方案--------------------
检查下代码。进行单步的调试和打印,来排查是哪里出现的问题。 给你看个 关于你那个错误的网上的一些解决方法。http://hi.baidu.com/xiaefun/blog/item/87fd5f82e96a3eaa0df4d2cb.html
------解决方案--------------------
我也碰到过这问题。问题一般出现在以下几点
1、去除BOM
2、不能出现除了XML外的其它字符
3、4、?>结束之后也不能有换行甚至一个空格
------解决方案--------------------
菜单栏-格式- 以UTF-8 无BOM格式编码
------解决方案--------------------
恩。。跟你一样
------解决方案--------------------

探讨

记事本的格式里没这一项啊?

------解决方案--------------------
你上面的代码是没问题的。你肯定是编码搞错了。
