Send the user to a different Drupal page.
This issues an on-site HTTP redirect. The function makes sure the redirected URL is formatted correctly.
Usually the redirected URL is constructed from this function's input parameters. However you may override that behavior by setting a <em>destination</em> in either the $_REQUEST-array (i.e. by using the query string of an URI) or the $_REQUEST['edit']-array (i.e. by using a hidden form field). This is used to direct the user back to the proper page after completing a form. For example, after editing a post on the 'admin/node'-page or after having logged on using the 'user login'-block in a sidebar. The function drupal_get_destination() can be used to help set the destination URL.
This function ends the request; use it rather than a print theme('page') statement in your menu callback.

Parameters
$path A Drupal path or a full URL.
$query The query string component, if any.
$fragment The destination fragment identifier (named anchor).
Code
<?php
function drupal_goto($path = '', $query = NULL, $fragment = NULL) {
if (isset($_REQUEST['destination'])) {
extract(parse_url(urldecode($_REQUEST['destination'])));
}
else if (isset($_REQUEST['edit']['destination'])) {
extract(parse_url(urldecode($_REQUEST['edit']['destination'])));
}
$url = url($path, $query, $fragment, TRUE);
// Remove newlines from the URL to avoid header injection attacks.
$url = str_replace(array("\n", "\r"), '', $url);
// Before the redirect, allow modules to react to the end of the page request.
module_invoke_all('exit', $url);
header('Location: '. $url);
// The "Location" header sends a REDIRECT status code to the http
// daemon. In some cases this can go wrong, so we make sure none
// of the code below the drupal_goto() call gets executed when we redirect.
exit();
