The php in this file works, as long as the html is gone, whats wrong with the html?

[code]<html>

Fixed! This code works:

[code]<?php

$user = $_POST["UserName"];
$pass = $_POST["PassWord"];
$UID = 1;

if ($_POST["UserName"] == "Thomas" && $_POST["PassWord"] == "**killedbyuse**") {

    setcookie("UserName", $user, time()+3600);
    setcookie("Password", $pass, time()+3600);
    setcookie("UID", $UID, time()+3600);

echo "<html>

</body>
</html>[/code]

But only if this is in there, for some odd reason:

[code]if ($UID == 1) {

echo "[admin]";

} else {

echo "[guest]";

}[/code]

Could anyone explain to me why?

Because you cant send headers/set cookies when something has been outputted before the uses of header/session_start or setcookie, ie HTML or spaces.
