PHP does not support that method directly as you have discovered.

Under normal circumstances we know that $value is a string, therefor
what is actually in $value is the question. If the code for *case "A"*
is not being executed then $value <> A.

The example above would indicate that there is a CONSTANT A that
$value is compared against. You are mixing problems.

Not true, the online manual simply indicates that a ; may be used
instead of a : period. Don't know why, I'd never do it that way - seems
to add confusion.

There is nothing wrong with that syntax. It is merely an expression
that ends up being true or not. Using : or ; for either case works as
tested.
