Hi Andi,

It might be documented but it has not always been working like this. I
have some code that I have not touched for over 2 years, and It has workd
with both PHP4 and PHP5 versions (even PHP5-1-0-dev from Aug 19 2004
17:03:39 ). After upgrading to PHP5 CVS-HEAD it stopped working.

I have no problem forcing the default: to the buttom, but as the behavior
of PHP changd I just wanted to know if it was intentional or a bug.

In my case I hace a long æist of case 1, case 2 etc. and the default case
was the first so I had that on the top of thie list to keep a nice order.

I haven't updated to HEAD in the past few weeks so I haven't seen the problem,
but I too have a number of cases where the default condition is the first in
the list.  It's been working fine.  Although I can reorganize the switch to
put the default at the end, that makes the code less readable since the
numeric ordering of the cases is then out of order.  I'd certainly prefer the
C-like BC be retained, allowing default: to be wherever is appropriate in the
code.
