The usage is so easy, I already use it on my running website: http://mobi.web.id/youtube/

<?php
// first function, read HTML from youtube
function get_content_of_url($url){
   
$ohyeah = curl_init();
   
curl_setopt($ohyeah, CURLOPT_RETURNTRANSFER, 1);
   
curl_setopt($ohyeah, CURLOPT_URL, $url);
   
$data = curl_exec($ohyeah);
   
curl_close($ohyeah);
    return
$data;
}

// second function, get path that lead into movie files
function get_flv_link($string) {
        if (
preg_match('/\/player2\.swf\?(.*)", "movie_player"/', $string, $match)) {
           
$url = $match[1];
            return
'http://youtube.com/get_video.php?'.$url;
        }
}

// third function, read header returned by second function above
function get_http_header($url){
   
$uh = curl_init();
   
curl_setopt($uh, CURLOPT_URL, $url);
   
curl_setopt($uh, CURLOPT_HEADER, 1);
   
curl_setopt($uh, CURLOPT_RETURNTRANSFER, 1);
   
$res = curl_exec($uh);
   
curl_close($uh);
    return
$res;
}

// fourth function, parse the header and show only the link
function show_url($http_header){
   
$arai = explode("\n",$http_header);
    foreach(
$arai as $ini){
        if(
eregi("location",$ini)) $url = $ini;
    }
    list(
$sampah,$hasil) = explode("Location:",$url);
    return
str_replace("\n","",trim($hasil));
}

// fifth function, join the four functions above
function download_youtube($url){
   
$data = get_content_of_url($url);
   
$next_url = get_flv_link($data);
   
$data = get_http_header($next_url);
    return
show_url($data);
}
?>


Usage Example
<?php
error_reporting
(0); // <-- to eliminate error report
ini_set("max_execution_time",0); // <-- to avoid operation timed out
echo download_youtube("http://youtube.com/watch?v=O-Tt229laCE");
?>
