Take a look at ob_start:

PHP Code:


<?php
  $time = date("h:i:s A");
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
    <head>
        <title><?php print "Current Time is {$time}"; ?></title>
        <style type="text/css">

        </style>
        <script type="text/javascript">

http://dynamicdrive.com/forums/showp...postcount=1337 — 4.1, 4.2. Solving 4.1 will fix your problem. Output buffering is overkill in this particular instance.

You are not allowed to change the headers after sending output, due to the way HTTP data is structured.

ok i changed my code to this and works fine now:

Code:

<?php 
session_start();
header("location: index.php");

$_SESSION['loggedIn'] = "false";

?>

do you think i should just session_destroy() instead of setting the login to false? would it be safer?
