header problem

[Clanstrom]

Hi guys. It's been a third day now, I am having problems with header. I have many included files which output echo before the header, so since I can't output them after the header, I used ob_start(); and ob_flush(); but still I am getting header problems.

If you wanted to created a login code. In which if user enters wrong credietials you might use echo "error";
but it is not working before, echo is being outputted before the header.

Anyone has any solutions for the problem?

Can you post the header code.

try this:

avoid <? ?> should be <?php ?> depends if your php.ini allowed the use of <? ?>

I had placed ob_start() is the middle, but when I placed it at the VERY top of my codes, it worked just fine. Thank you.

But, it is a good idea to close ob_start() with ob_flush? The site, seems to work just fine without it? Can i leave it there, without expection something bad to happen?

You can usually go without ob functions for header redirects if the header appears before any output (php generated or html).
