Cannot modify header information This problem how to solve, trouble big God moves!
Error: Warning:cannot Modify header Information-headers already sent by (output started at D:\AppServ\www\work\admin\fileu pload_admin.php:49) in D:\AppServ\www\work\conn\conn.php on line 5
I Baidu said can not before the header output anything, my header in the first line, has confirmed that there is no space, but he is an error. Then I looked at the wrong thing is a echo, I write off after he gave an error to the next game echo. The wrong number of lines I have marked in red this file all the functions can be implemented, can be an error, if the header is deleted, the displayed string is garbled, trouble big God moves!
Header ("content-type:text/html; Charset=utf-8 ");

------Solution--------------------
The error message tells you
On line 5th of D:\AppServ\www\work\conn\conn.php
Found output at line 49th of D:\AppServ\www\work\admin\fileupload_admin.php
But you didn't give the two files, or the wrong one.
If this code is D:\AppServ\www\work\admin\fileupload_admin.php,
Then the content of D:\AppServ\www\work\conn\conn.php should be given.
------Solution--------------------
The probable Cause:
1. The file itself contains the BOM header, which causes the output to precede the header function and thus reports an error.
2. Enable other functions that may send headers, such as cookies and session
3. Another file contained may have errors or warning, resulting in the output.
4. The other files included are output (before the header).
Look at you for reasons. It is most likely the reason for the BOM header or the output of other files. (2,3 is unlikely)
