php标头已发送错误
可能重复:
已由 PHP 发送的标头
我有一个 php 文件，其中包含以下代码:
I have a single php file, with this code in it:
<?php header("Location: somepage.php"); ?>
在 php 开始或结束标记之前或之后绝对没有空格，我得到了
Absolutely no spaces before or after the php opening or closing tags and I am getting the
Warning: Cannot modify header information - headers already sent by (output started at C: ... est.php:1
通常当我收到此错误时，1 是问题的行号，但在这种情况下，第一行没有任何额外的空格.我在页面上只有此代码，不包括任何其他文件.
Usually when I get this error, the 1 is the line number of the problem, but in this case line one doesn't have any extra whitespace. I only have this code on the page and I am not including any other files.
我在 windows xp 上使用 xampp.任何想法发生了什么或我如何追查真正导致问题的原因.
I'm using xampp on windows xp. Any ideas what's going on or how I can track down what's really causing the problem.
谢谢
