The two cases are not the same. In the case above, all operators are
ternary --with equal precedence-- but in your case, the operators are
of different precedence.
As I pointed out to you in e-mail, both of the ternary forms in my
original question would evaluate to the same thing if they were in s C
program. That, admittedly, is no reason why they should evaluate to
he same thing in PHP but it was enough to make me wonder...
