// to the ftp username
$ftp_userpass="user";

// File name or path to upload to ftp server

// Establishing ftp connection
$ftp_connection = ftp_connect($ftp_server)
    or die("Could not connect to $ftp_server");

if( $ftp_connection ) {
    echo "Successfully connected to the ftp server!";

    // Logging in to established connection with
    // ftp username password
    $login = ftp_login($ftp_connection, $ftp_username, $ftp_userpass);

    // Checking whether logged in successfully or not
    if($login) {
        echo "<br>logged in successfully!";

        if (ftp_put($ftp_connection,
                "uploadedfile_name_in_server.txt", $file, FTP_ASCII))
