Get response from PHP Script

[nicoh]

Hi, Im working in a video downloader. I want to put the code of the video in an input an then the video starts downloading.

The problem is that Youtube ask for a code to start the download.

I've done a PHP script that get that code but I dont know how to use the code Ive get on AMS.

The script is:

<?php
function getHeaders($varurl) {
    $host = "www.youtube.com";
    $url = "/v/".$varurl;
    $session = "";
    $fp = fsockopen ($host, 80, $errno, $errstr, 45);
    if ($fp) {
        fputs ($fp, "GET $url HTTP/1.0\r\n\r\n");
        while (!feof($fp)) {
            $char = fgetc($fp);
            if($char === "\n") {
                if (ord($header) === 13) { 
                    return($session);
                } else {
                    $arrValue = split(": ", trim($header));
                    if ($arrValue[0] == "Location") {
                        parse_str($arrValue[1], $getvars);
                        $session = $getvars['t'];
                    }
                }
                unset($header);
            } else { 
                $header = $header.$char;
            }
        }
        fclose ($fp);
    }
}
if ($_GET['v'] != "") {
    $videoIds = $_GET['v'];
    $videoUrl = "http://www.youtube.com/get_video.php";
    header("Location: ".$videoUrl."?video_id=".$videoIds."&t=".getHeaders($videoIds));
    exit();
}
?>

I need this part:"&t=".getHeaders($videoIds));"

Thanks and apologize for my bad english :S
