        $parts[2] = $parts2[0];


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);
      }


Is there a simplier solution?


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.

Chris -

That you for the helpful comments! The reason I use the strtotime() up front is to make sure "junk" data has not been placed in the fields. My client tests by putting "%^&#$" into fields, and that creates a problem with their php 4.2.x but not with my 4.3.9. The strtotime() took care of the problem...
