If you want a unique filenames to prevent overwritting is to use sha1_file().

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST')
	{
		if (isset($_FILES['pic']))
		{
			$file = $_FILES['pic'];

			if ($file['error'] == UPLOAD_ERR_OK)
			{
				$name = sha1_file($file['tmp_name']);
				$pathInfo = pathinfo($file['name']);
				if (isset($pathInfo['extension']))
					$name .= '.'.$pathInfo['extension'];

				if (move_uploaded_file($file['tmp_name'], $uploaddir.$name))
				{
					// ..ok..
				}
				else
				{
					// ..failed..
				}
			}
		}
	}
?>

Its unlikely 2 files will ever get the same filename, unless they are the same.
