bom header php process

PHP header
Warning: Cannot modify header information - headers already sent by (output started at D:\AppServ\www\xinR_process.php:1) in D:\AppServ\www\xinR_process.php on line 29
有什么办法能追踪到 哪里输出了 我实在找不到问题所在了 所有的代码我都看了 代码是我之前编写好的 我只是重装了系统 将代码 也txt格式上传到网上 然后下载下来就出现了这个问题

------解决方案--------------------
output started at D:\AppServ\www\xinR_process.php:1

第1行已经发送了 header 
然后在1-29行之间你向页面输出了内容?

header之前不能向页面输出任何内容,除非你使用了
ob_start();
....
ob_clean();
------解决方案--------------------
BTW,一般来说,第一行存在非你本人发送的header,极有可能是BOM
