[FX.php List] PHP question...

[Leo R. Lundgren]

I'd say the same. Bob; If you're having trouble (getting errors?)  
using header() in your body, maybe you sent some data by mistake  
already?

I don't understand the reason to use ob_get_contents() though, in my  
opinion this one is a lot neater: http://pastie.org/462601

Note that ob_start() must come before any other output, to make sure  
that you can send the headers if you want to later on in the script.

As a sidenote, you don't even /have/ to call ob_end_flush() if it's  
the last thing you do; PHP does that automatically. However, it's good  
practice to finish what one started, so keep it ;)
