Hmmm. The only time I ever use anything remotely like that is in a loop or
other code are where I don't want anything to happen ie
for ($foo=0;$foo<=10;$foo++) {

I believe this is just C syntax legacy, although I think you can pass an
argument to a C compiler to raise a warning when this kind of statements
are
found, that can't be done in PHP. Anyway, is just the way
compiler/interpreters are made when a language has a C syntax style, it's
just more efficient for the compiler to do what you're told and don't ask
too many questions (if you mess up and your program is slow or buggy is
your
fault not the compiler's).
