Why $parts2?

Just use $parts instead, like you did in the other two blocks.

Change it to:

>        if (strpos($date, "/") > 0) {
>          $parts = explode("/", $date);
>        } elseif (strpos($date, "-") > 0) {
>          $parts = explode("-", $date);
>        } else {
>          $parts = explode(".", $date);
>        }

How about strtotime()? In your function you're pretty much only
accepting a certain number of formats for your date already so you could
probably go with just passing the date (in whatever format it's given)
to strtotim() and check for a 'false' or a timestamp.
