I was on the fence about this, too.  From what I've
heard/read/understood, switch statements become more efficient than
if/else when there are about 4 or more test cases (switch statements
have a considerable overhead to setup).  This is from C, so frankly I
don't know if it holds true under PHP, too.  I'd be interested to see
both cases run through some profiler and I'll change the PCOM
accordingly :)

false.

The catch all is implied.  If the type isn't known, the type should be a
string, which is what mysql_fetch_row() itself always returns - so no
need to do any casting.
