$fp = fopen($file, 'r');

$ftp_server = "REMOTE SERVER";
$ftp_user_name = "REMOTE USER";
$ftp_user_password = "REMOTE PASS";
$rempath = "/public_html/";

// set up basic connection
$conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server"); 

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

ftp_chdir($conn_id, $rempath);

// try to upload $file
if (ftp_fput($conn_id, $file, $fp, FTP_ASCII)) {
    echo "Successfully uploaded $file\n";
} else {
    echo "There was a problem while uploading $file\n";
}

// close the connection and the file handler
ftp_close($conn_id);
fclose($fp);

这行有错别字：-

$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

$ftp_user_pass 没有在您的脚本中定义：-

$ftp_user_password <-- what was defined
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

如果这有帮助，请确保不要将头撞到墙上
