ho script php che consente di scaricare video da youtube con php.
codice:
<body>
        <form action="" method="post">
            Inserisci il percorso del file da scaricare (http://www.youtube.com/watch?v=UF8uR6Z6KLc)
            

            Per esempio, se il link è http://www.youtube.com/watch?v=UF8uR6Z6KLc sarà necessario inserire watch?v= UF8uR6Z6KLc
            


            <input type="text" name="link" size="50" />
            <input type="submit" value="Preleva link" />         
            <?php
            if (!empty($_POST['link'])) {
                $uri = ($_POST['link'][0] != '/' ? "/" . trim($_POST['link']) : trim($_POST['link']));
                $sito = 'www.YouTube.com';
                $f = getFile($uri, $sito);
                if ($f) {
                    $f = explode("fmt_url_map\": \"", $f);
                    $d = explode("\"", $f[1]);
                    $link = explode("|", urldecode($d[0]));
                    echo "<center><h4>Link to file:</h4> <textarea cols='50' rows='10'>" . urldecode($link[2]) . "</textarea></center>";
                } else {
                    echo "Bad link";
                }
            }

            function getFile($url, $sito) {
                $other_info = "User‐Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; it; rv:1.9) Gecko/2008052906 Firefox/3.0\r\n" . "Accept‐Language: it‐it,it;q=0.8,en‐us;q=0.5,en;q=0.3\r\n" . "Keep‐Alive: 300\r\n" . "Connection: Keep‐Alivern\r\n\r\n";
                if (!($sock = fsockopen($sito, 80))) {
                    die("Errore connessionen");
                }
                fputs($sock, "GET $url HTTP/1.1\r\n" . "Host: $sito\r\n" . $other_info);
                $f = "";
                while (!feof($sock)) {
                    $f .= fgets($sock);
                    fclose($sock);
                }
                return $f;
            }
            ?>
        </form>
    </body>
quando provo a eseguirlo mi compaiono queste tre righe all'infinito:
codice:
Warning: feof(): 1 is not a valid stream resource in /web/htdocs/www.mattepuffo.com/home/vyt/index.php on line 37

Warning: fgets(): 1 is not a valid stream resource in /web/htdocs/www.mattepuffo.com/home/vyt/index.php on line 38

Warning: fclose(): 1 is not a valid stream resource in /web/htdocs/www.mattepuffo.com/home/vyt/index.php on line 39
ho provato con vari video diversi.
l'utimo è questo: http://www.youtube.com/watch?v=PBC1Y...ture=topvideos
ho inserito solo: watch?v=PBC1Y_TDyEI&feature=topvideos
