Something like this:

In logout link:

<a href="http://www.example.com/logout.php?redirect=<?=urlencode('http://www.index-page.com/index.php')?>"> Logout </a>

On logout.php page:

<?
    // destroy session
    header('location:'.urldecode($_GET['redirect']));
    die();
?>

you can not use echo before headers if not it would generate Warning: Cannot modify header information - headers already sent by

    $redirect = "Location: http://". $_GET['redirect'];
    header($redirect);

You shouldn't need the additional '

$redirect = "Location: http://".$_GET['redirect'];

Here is an example to redirect user to Google

$link='http://Google.com';
header("location: $link");

You can make it a function

function redirectUser($link){
    header("location: $link");
}

And then you can call it like

redirectUser('http://google.com');

Or

echo redirectUser('http://google.com');

No errors will happens!

I Advise you to use die(); After the redirection code, to abort the comming codes

You can only use redirect without echo:

header("Location: http://".$_GET['redirect']);

the problem is here

echo $redirect = "'Location: http://".$_GET['redirect']."'";
//redirects to index
header($redirect);

You should not have to use echo before header, this will cause warning header already sent.

Use it like this

$redirect = "Location: http://".$_GET['redirect'];
//redirects to index
header($redirect);
