i’ve used a sample found on online and applied it to my code:

<?php
session_start();
if (isset($_REQUEST["email"]))
{
    $_SESSION["name"] = true;
    $host = $_SERVER["HTTP_HOST"];
    $path = dirname($_SERVER["PHP_SELF"]);
    $sid = session_name() . "=" . session_id();
    header("Location: index.php?$sid");
    exit;
}
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
...
...
and rest of the html code

When I open this page, I got an error: 

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /data/server/user/directory/sub-directory/login.php:1) in /data/server/user/directory/sub-directory/login.php on line 2

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /data/server/user/directory/sub-directory/login.php:1) in /data/server/user/directory/sub-directory/login.php on line 2

I looked around to resolve this issue and saw few posts about this in this site also, but I just can’t get a good grip on this…can’t find the answer.

Please help.

Thanks.

    NotePad is known to insert BOM in the beginning of the text file. When you save the file, please make sure you don’t select Unicode or UTF-8 as encoding.

    You can confirm if BOM is inserted by making a hex dump of the file. You can use this utility to do it,

    If it doesn’t start with 0x3C, you got BOM.
