function upload_file ($file_object, $file_name, $path) {
//$file_object 本地文件名，不包括路径
//$file_name 上传后的文件名
//$path 上传到的目录
if($file_object != "") {
$ftp_user_name='XXXXX';
$ftp_user_pass='xxxxxx';
$ftp_server='xxxxxxxxxxxxxxxx';
$conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server");
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

if ((!$conn_id) || (!$login_result)) {
echo "FTP connection has failed!";
exit;
}

$upload = ftp_put($conn_id,$path.$file_name, $file_object, FTP_BINARY);
echo $path.$file_name;
echo $file_object;
if (!$upload) {
echo "FTP upload has failed!";
return false;
} else {
echo "Uploaded $file_object to $ftp_server as $path.$file_name";
}
ftp_close($conn_id);

}
return true;

}

为什么每次运行都显示出"FTP upload has failed!"？

我试过把$file object 加上本地的路径，也是不行。
请各位高手指教！
