Not so, O'wise one.
This will work:
switch(1)
{
case $a > $b:
/* whatever
break;
case $c == 1:
/* whatever
break;
case $d == 'this works':
/* whatever
break;
}
Granted, it's not the normal way a switch works in some other
languages, but it does work in PHP. :-)
That is just so wrong, it can't actually be taken seriously. There is
simply no justification for such broken logic.

I take it seriously. In fact, I think it's a very good method of
making several different comparisons in one control structure. For
me, it is easy to understand, document, and maintain. Obviously, your
mileage varies.
But besides the point, all I was showing was that your claim --
A switch works when a single test can dispatch all possible
branches. If you have a series of tests where each looks for a
different subset of conditions, you need an elseif.
-- was false. I don't need an elseif and never have. There has always
been a way around using an elseif. The powers that be could boot that
control and I would never miss it.
