ARRAY是上传后重命名的文件名的前面-PHP

我正在运行一个PHP脚本，从HTML表单上传文件，重命名它们并将它们放在我的服务器上。它正在上传和重命名，但现在每个文件名都以单词"Array"开头
即：ArrayTest Document v1.0.pdf
我非常确信它不是我的$newfn变量，因为我在表中显示了它，但它没有显示出来。

//This gets all the other information from the form
$name=$_POST['docname'];
$version=$_POST['docver'];
$date=$_POST['docdate'];
$type=$_POST['doctype'];
$author=$_POST['docauth'];
$file=$_FILES['uploaded']['name'];
//target directory is assigned
$target = $directory;
$target = $target . basename($file) ;
//grab file extension
$filetypes = array(
'image/png' => '.png',
'image/gif' => '.gif',
'image/jpeg' => '.jpg',
'image/bmp' => '.bmp',
'application/pdf' => '.pdf');
$ext = $filetypes[$_FILES['uploaded']['type']];
//generate new filename variable "name v??.xxx"
$newfn = $name . ' ' . 'v' . $version . $ext;
//Check to see if file exists
if (file_exists($directory . $file))
{
echo $_FILES["uploaded"]["name"] . " already exists. ";
}
else
{
//if its a new file, change name and upload
    if (move_uploaded_file($_FILES["uploaded"]["tmp_name"],
        $directory . $_FILES["uploaded"] . $newfn))
        {
        echo "The file ". basename($file). " has been uploaded";
        }
        else
        {
        echo "Sorry, there was a problem uploading your file.";
        }
}

我觉得它与move_uploaded_file命令中的$FILES['uploaded']部分有关。我试过在谷歌上搜索，但一提到"数组"，我的谷歌结果就完全不同了。

好的，多亏了下面的内容，我解决了它。对于未来的任何人，我都删除了整个$_FILES阵列，因此代码读取为

//if its a new file, change name and upload
if (move_uploaded_file($_FILES["uploaded"]["tmp_name"],
    $directory . $newfn))

现在，所有内容都以正确的名称结构上传。谢谢
