标题重定向与＆符问题

Question

I am getting the current (dynamic) page URL with:

$redirect = basename($_REQUEST['redirect']);
$redirect = base64_encode($redirect);   

And that page URL might then be

www.domain.com/somepage?filter=1&category=1&limit=10

I then perform the action and want to redirect the person back to that dynamic page they were on with:

$redirect = base64_decode($redirect);
$output .= header_redirect($redirect);

But it's redirecting me to

www.domain.com/somepage?filter=1&category=1&limit=10

How can I fix that so that the & becomes & in the redirected URL?

The header_redirect function is just:

function header_redirect ($redirect_url)
{
echo "<script>window.location.replace('" . $redirect_url . "');</script>";
}

Seems like it is parsing the HTML entity of the URL. Use html_entity_decode() to reverse it.

function header_redirect ($redirect_url)
{
echo "<script>window.location.replace('" . html_entity_decode($redirect_url) . "');</script>";
}
