Upload file to FTP, directly from a URL

Question

I tried a lot of ways to do something like "php file reads the URL file, write another same one inside ftp"

Code tested 1:

<!-- language: lang-php -->
<?php
    if(empty(  $_POST['q']))
        exit('Use o parametro q');

    $url = 'https://www.youtube.com/watch?v=' . $_POST['q'];

    $ch = curl_init();
    $Variaveis = array(
        'format' => 'json',
        'video' => $url
    );
    $url = 'http://youtubeinmp3.com/fetch/?' . http_build_query($Variaveis);

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $response = curl_exec($ch);
    curl_close($ch);

    $dados = json_decode($response, true);

    $src = fopen($dados['link'], 'r');
    $dest = fopen($_POST['f'] . '.mp3', 'w');
    stream_copy_to_stream($src, $dest);
?>

In FTP it copies files with extension . txt . png (Direct files), when it is the URL I need, it creates the file, but does not write, and gets 0kbs.

Now when testo on localhost here at home works normal.

Try uploading in stages... And always close the connection.

while (!feof($src)) 
{ 
    stream_copy_to_stream($src, $dest, 1024);// no caso 1024 bytes por vez. 
}
fclose($src); 
fclose($dest);
