Is there an efficient way of detecting if a jpeg file is corrupted?

Background info:
solutions needs to work from within a php script
the jpeg files are on disk
manual checking is no option (user uploaded data)

I know that imagecreatefromjpeg(string $filename); can do it. But it is quite slow at doing so.

Does anybody know a faster/more efficient solutions?
