   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.
