Rather than use the $_FILES variable, it would be better to use the applicable Zend code, considering that you're using Zend as your framework:
if (!$form->isValid()) {
print "Uh oh... validation error";
}
if (!$form->docupload->receive()) {
print "Error receiving the file(s)";
}
$files = $form->docupload->getFileName(); // result should be an array in this case
