header(); not working after log out ]session_destroy()]

Question

I have this code for my logout.php:

<?php

session_start();

$_SESSION = array();

if (ini_get("session.use_cookies")) {
$params = session_get_cookie_params();
setcookie(session_name(), '', time() - 42000,
    $params["path"], $params["domain"],
    $params["secure"], $params["httponly"]
);
}

session_destroy();
    header( "Location: index.php" ); //to redirect back after logging out
?>

Problem is that the header doesn't work. I don't know if it has anything to do with the code above.. but I don't think so, cause it works on localhost - wamp server. Is it then because of the server I'm using? Or is it something wrong in the code?

Thanks!

"Doesn't work" is not an error message, please explain in what way it doesn't work, and ensure that you have `error_reporting` and `display_errors` enabled. — DaveRandom, Feb 26 '13 at 11:09
@DaveRandom it stays on on logout.php, instead of going to index.php — Alina Gabriela, Feb 26 '13 at 11:10
Try : Change `header( "Location: index.php" );` to `header( "location: index.php" );` 'location' NOT CAPITAL L — Prasanth Bendra, Feb 26 '13 at 11:11
@PrasanthBendra where did you read that. The capital L is ok. — Mihai Iorga, Feb 26 '13 at 11:12
@MihaiIorga there's no error. after I click log out I get stuck on the logout.php page, which is just a blank page, no error, nothing, instead of being redirected back to index.php as I expect by using header( "Location: index.php" ) — Alina Gabriela, Feb 26 '13 at 11:15
@AlinaGabrielaSingeorzan maybe you have some bytecode before `headers` please remake that file. — Mihai Iorga, Feb 26 '13 at 11:17
@PrasanthBendra Header names are case insensitive. There is a problem with that header, but that is not it - `Location` URIs should be absolute according to RFC2616. However afaik *all* web browsers will accept relative URIs. — DaveRandom, Feb 26 '13 at 11:20
A blank page often means that your script is throwing an error but you haven't configured PHP to display error messages. That's something you need to fix before you go further; it's impossible to code without the aid of error messages. Here's a [brief explanation](http://stackoverflow.com/a/5680885/13508). — Álvaro González, Feb 26 '13 at 11:21
@ÁlvaroG.Vicario I added " ini_set('display_errors', 1); error_reporting(~0); " but it doesn't show any error still — Alina Gabriela, Feb 26 '13 at 11:28
@AlinaGabrielaSingeorzan - Second step is to fire Firebug (or your browser's debugging tool) and check whether the header is actually sent. — Álvaro González, Feb 26 '13 at 11:30
@AlinaGabrielaSingeorzan - Fire Firebug and check whether the header is actually sent. You can see if in the "Net" panel. — Álvaro González, Feb 26 '13 at 12:55

It's because of the Header Redirect needs the data Buffering to be on, It's Probably disabled on the server, Try to add ob_start(); After you session_start();

try this Instead: `echo ''; exit; ` – ImadBakir Feb 26 '13 at 11:32
Nope, it doesn't. Data buffering is just a hack to write spaghetti code where headers and mixed with regular output. – Álvaro González Feb 26 '13 at 11:32

Try it:

header( "Location: http://hostname.com/full_path/index.php" );

Or if are getting the error in using the header then try this code:

echo "<script>window.location.href='http://hostname.com/full_path/index.php'</script>";

Thanks, I tried the full path before - no result. Now I tried the second suggestion - works on my local host, but not on my domain.. so my guess is that is has something to do with the server – Alina Gabriela Feb 26 '13 at 11:37

Try this perhaps it works:

echo '<META HTTP-EQUIV="Refresh" Content="0; URL=index.php">';    
exit;
