What does this code do?

[free]

Can someone tell me what this code does? I can tell that it's a redirect of some kind...

<?php
$request_method = $_SERVER["REQUEST_METHOD"];
if($request_method == "GET"){
$query_vars = $_GET;
} elseif ($request_method == "POST"){
$query_vars = $_POST;
}
reset($query_vars);
$t = date("U");

$file = $_SERVER['DOCUMENT_ROOT'] . "/../data/gdform_" . $t;
$fp = fopen($file,"w");
while (list ($key, $val) = each ($query_vars)) {
fputs($fp,"<GDFORM_VARIABLE NAME=$key START>\n");
fputs($fp,"$val\n");
fputs($fp,"<GDFORM_VARIABLE NAME=$key END>\n");
if ($key == "redirect") { $landing_page = $val;}
}
fclose($fp);
if ($landing_page != ""){
header("Location: http://".$_SERVER["HTTP_HOST"]."/$landing_page");
} else {
header("Location: http://".$_SERVER["HTTP_HOST"]."/");
}


?>

in a nutshell: it takes the submitted form data and saves all the fields to a file
then it redirects you to the landing page or to the root directory (depending on what was specified earlier)
