[Resolved] Header Output

[zzz]

What's an easy replacement for the:

header("Location: file.php");

I have some conditional script, and if conditions are met is just sends to the file with the string above. The problem is that the file where it points already has heade include. Naturally I get the following error:

Warning: Cannot modify header information - headers already sent by...

What's a work around this?

show us the code for the page that you want to redirect FROM after some conditions

Here's an abbreviated version of that index.php page:

<?
include("header.php");
?>
...some HTML code...
<?
if (!$HTTP_POST_VARS['username'] || !$HTTP_POST_VARS['password']) {
include("file01.html");
exit;
}
if (!$login) {
include("file02.html");
}
else {
include("file03.html");
}
?>

file01.html:

<?
header("Location: index.php");
exit;
?>

The error is the following:

Warning: Cannot modify header information - headers already sent by (output started at /mysitepath/header.php:3) in /mysitepath tothatpage/file01.html on line 2

The error you get normally means there is some sort of output before the header(); function. Check for any output whether HTML or another PHP error that occurs before the header();

there obviously cuz he includes file01.html that has the header() function, but above it he has "...some HTML code..." which is causing the error

Ok, now that we all agree there's a problem, so what's the solution?

What I was trying to find out from the beginning was:

Is there another way of saying something like: If there's a problem authenticating just reload this page; instead of "setting header". The file01.html is basically called from within the index.php...

put this:

ob_start();

before this line in your index.php

include("header.php");
