重命名服务器文件错误（http包装器不支持重命名）[PHP]

Question

On my page users can upload documents, which will be saved in a user specific folder. the directories are stored in a url: http://localhost/folder/user/documentA_user_timestamp.ext inside a database.

Users can also delete a file, which deletes the file's entry inside the database but i want the file to be moved to a specified archive folder. However i always get this error message when the php rename() tries to do its work:

http wrapper does not support renaming in...

I can't seem to get my head around the error message and figure out whats the cause for it

$filepath = $_POST['file'];
$archivePath = FILESYS_DOCS_ARCHIVE . basename($filepath);

if (!file_exists(FILESYS_DOCS_ARCHIVE)){
    mkdir(FILESYS_DOCS_ARCHIVE, 0777);
}

$success = rename($filepath, $archivePath);

if ($success){
    echo "SUCCess";
} else {
   echo $archivePath;
}
