php FTP from one site to another.

Hi i want to use something like this to download podcast mp3 from one server to my server.
I was wondering if i could put something like
http://www.yoursite.com/mp3file.mp3 and then ftp that into my server? Without having to download it to my computer.

// variables
$ftp_server = "<IP>";
$ftp_user_name = "<username>";
$ftp_user_pass = "<password>";
$destination_file = "images/catalogue/".$_FILES['image']['name'];
$sourcefile = $_FILES['image']['name'];

// set up basic connection
$conn_id = ftp_connect($ftp_server); 

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); 

// check connection
if ((!$conn_id) || (!$login_result)) { 
       echo "FTP connection has failed!";
       echo "Attempted to connect to $ftp_server for user $ftp_user_name"; 
       exit; 
   } else {
       echo "Connected to $ftp_server, for user $ftp_user_name";
   }

// upload the file
$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY);  // line 30

// check upload status
if (!$upload) { 
       echo "FTP upload has failed!";
   } else {
       echo "Uploaded $source_file to $ftp_server as $destination_file";
   }

// close the FTP stream 
ftp_close($conn_id);
