Problem with Header()

bb_sarkar

Hello everyone, I have a big problem with the header function. I use it like this:

//------------------------------------------------------------------
header("Location: http://127.0.0.1/page1/php/Admin.php");
exit;
//------------------------------------------------------------------

and it returns with this error message:

Warning: Cannot modify header information - headers already sent by (output started at C:\Inetpub\wwwroot\page1\php\authenticate.php:1) in C:\Inetpub\wwwroot\page1\php\authenticate.php on line 15

I read somewhere in the forums that you cannot have any output to the browser prior to that but I don't.. Here is all my html code above.

<?php echo "<?xml version=\"1.0\" encoding=\"iso-8859-1\"?".">"; ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title> Welcome to my website </title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
</head>

<?php
if ($_SERVER['REQUEST_METHOD'] != 'POST')
{
header("Location: http://127.0.0.1/page1/php/Admin.php");
exit;
}

PLEASE SOMEONE HELP!!! THANK YOU = )

if you're trying to use header put it before any echos and any html.

<?php
if ($_SERVER['REQUEST_METHOD'] != 'POST') { 
     header("Location: http://127.0.0.1/page1/php/Admin.php"); 
     exit; 
}
?>
<html>
<head><title></title></head>
<body></body>
</html>

It worked!

I understand that header() info should go before anything else.
But I am processing some multilingual data and based on some form values the header() should be written dynamically using some charset information I retrieve from a class. Plus I have some session stuff I have to deal with as well.

session_start();
require("lib/YakuNuke.class.php");
require("lib/FileUpload.class.php");
require("lib/FileWriter.class.php");
// prepare header for correct language display
$enc = new HTMLEncoding($_REQUEST["targetlang"]);
header("Content-type: text/html; ".$enc->getEncodingHeader());

That would print something like "charset=Shift_JS"

Now I initially wrote it to work on a Windows-PHP machine... and it works fine. Yet on LAMP it keeps on giving me the "Warning: headers already sent blabla".
What can I do to solve it?

thnx
