Putting together answers from Peter Bailey and Cmyker you get something like:

 $value) {
    if (strpos($key, 'HTTP_') === 0) {
        $chunks = explode('_', $key);
        $header = '';
        for ($i = 1; $y = sizeof($chunks) - 1, $i < $y; $i++) {
            $header .= ucfirst(strtolower($chunks[$i])).'-';
        }
        $header .= ucfirst(strtolower($chunks[$i])).': '.$value;
        echo $header."\n";
    }
}
$body = file_get_contents('php://input');
if ($body != '') {
  print("\n$body\n\n");
}
?>

which works with the php -S built-in webserver, which is quite a handy feature of PHP.
