problem med move_uploaded_file

Hej,

Jeg er ny i PHP - ved at konvertere fra ASP.

Jeg sidder med et problem med move_uploaded_file.

<?
$uploaddir = "/uploads/";
$uploadfile = $uploaddir. $_FILES['userfile']['name'];

print "<pre>";
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
    print "File is valid, and was successfully uploaded. ";
    print "Here's some more debugging info:\n";
    print_r($_FILES);
} else {
    print "Possible file upload attack!  Here's some debugging info:\n";
    print_r($_FILES);
}
print "</pre>";
?>

fejlen ser sådan ud:
Warning:  move_uploaded_file(/uploads/SW_hjoerne.gif): failed to open stream: No such file or directory in C:\Apache2\htdocs\phpsite\fileupload.php on line 14

Warning:  move_uploaded_file(): Unable to move 'C:\WINDOWS\TEMP\php63.tmp' to '/uploads/SW_hjoerne.gif' in C:\Apache2\htdocs\phpsite\fileupload.php on line 14
Possible file upload attack!  Here's some debugging info:
Array
(
    [userfile] => Array
        (
            [name] => SW_hjoerne.gif
            [type] => image/gif
            [tmp_name] => C:\WINDOWS\TEMP\php63.tmp
            [error] => 0
            [size] => 239
        )

)

Er det et problem med stien, eller er det en skriverettighed eller lign. der ikke er sat.

Jeg vil gerne have flyttet filen til c:apache2/htdocs/phpsite/uploads
