如何允许用户选择将文件上载到的位置？

I have a basic upload form 

<html>
<head>
<title>Upload a File</title>
</head>
<body>
<font face=verdana size=2>
<form enctype="multipart/form-data" method="post" action="upload_file.php">
<input type="hidden" name="MAX_FILE_SIZE" value="25000">

<p><strong>File to Upload:</strong><br>
<input type="file" name="our_file" size="30"></p>

<P><input type="submit" name="submit" value="Upload File"></p>

</form>
</font></body>
</html>

And the php file

<?

if ($our_file != "") {

    copy($our_file, "upload/$our_file_name") or die("Couldn't Upload the file!");  

} else {

    die("No input file specified");
}

?>

<html>
<head>
<title>Successful File Upload!</title>
<body><font face=verdana size=2>

<B>Success!</B>

<P>You sent: <? echo "$our_file_name"; ?>, a <? echo "$our_file_size"; ?> 
byte file with a mime type of <? echo "$our_file_type"; ?>.</p>

</font></body>
</html>

I would like the user to be able to choose what directory he uploads the file to. I assume I would need a form for the HTML side of it but I don't know what to add in the PHP. Any help?

    Assuming you only have a fixed number of directories, include a select in your HTML.

    @thephpdeveloper, As long as your permissions are set right for your directories, I don't think selecting where you upload is going to be anymore dangerous than any other upload. I am by no means a security expert. Just make sure you're preventing injection, etc.

    <select name="selectDir">
    <option value="1">This Directory</option>
    <option value="2">That Directory</option>
</select>


// on your submit
if( $_POST['selectDir'] === '1' ){
    $dir = './thisdir/';
}elseif( $_POST['selectDir'] === '2' ){
    $dir = './thatdir/';
}else{
    die('You did not enter a valid value');
}

if ($our_file != "") {
    copy($our_file, $dir."".$our_file_name) or die("Couldn't Upload the file!");      
}else{
    die("No input file specified");  
}
