Answer / luan nguyen

you get header already sent when you call header() after you
have posted other data to the browsers.
Example:

<?php

echo "Hello World";
header("Location: http://new.url.com");

?>

Answer / suren

if u print any message on the browser using echo statement
or any html tags before using the "session_start()" like
statements in the scripts.
if u want to overcome that problem
simply write "ob_start();" at the very starting of script
and "ob_end_flush();" at the end.

Answer / dhiraj

when we are using the session variable..and want to start
our session.. we use session_start(); in the very first
line.
anything occur before this line, even a single space we get
the headers already sent error.
To overcome this problem, we can use ob_start(); at the
very first line and ob_end_flush(); at the end of the
script..
