FTP PHP Doesnt Overwrite Existing File

I want the following script to overwrite the original file automatically if the file name is exactly the same, what do I need to change?

<?php

$ftp_server = "ftp.xxxxxx.com";

$ftp_username  = "xxxxxx";

$ftp_password  =  "xxxxxx";

//setup of connection

$conn_id = ftp_connect($ftp_server) or die ("could not connect to service");

//login

if(@ftp_login($conn_id, $ftp_username, $ftp_password))

{

header( 'Location: http://www. xxxxxx .com' );

}

else {

echo "could not connect";

}

// turn passive mode on

ftp_pasv($conn_id, true);


$file = $_FILES["uploadedfile"]["name"];

$remote_file_path = "/xxxxxx/xxxxx/".$file;

ftp_put($conn_id, $remote_file_path, $_FILES["uploadedfile"]["tmp_name"], FTP_BINARY);

ftp_close($conn_id);

?>

Code (markup):

 

ftp_put() usually overwrites existing files. Perhaps make sure the file permissions are right?

 

as in CHMOD?

 

login to shell then
