troubleshooting (:Cannot modify header information - headers already sent by")

newrehmi · February 23, 2010

hellow all, sorry if this kind of topic already discussed for many times.

I am just troubleshooting my problem to the root of it, and still can't find the answer.

so this is my code, without <html> tags or whatsoever. Just this in my test.php.

<body><?php header("location: index.php");?></body>

and when I open the test.php, it gave me those "Cannot modify header information - headers already sent by... blabla bla"

but, when I remove the <body> tag, it redirect normally. I already do those outputbuffering=on and still having the same problem..

May someone list a what is my actual problem?

Thanks so much in advance!

A header cannot be changed once any output has been started. It will shout at you otherwise

The most important part of that error msg is where it says output started at ...

that will tell you where your issue is
