Is it necessary for the directory specified in $uploaddir to be present for successful file uploads?

Yes, it is necessary for the directory specified in $uploaddir to be present for successful file uploads. If the directory does not exist, the file upload will fail. To solve this issue, you can use the PHP function `mkdir()` to create the directory if it does not already exist before attempting to upload the file. 

$uploaddir = 'uploads/';

if (!file_exists($uploaddir) && !is_dir($uploaddir)) {
    mkdir($uploaddir, 0777, true);
}
