Classes are intended to be structured data storage. You should define
a structure of the class before using the class.
You can set the value of the $somevar anytime later, when using an
object of class a.
$d->somevar = true;
and the next call to $d->b() will print nothing.
But you won't be able to assign a value to $somevar, if it is not
declared in the class.

the method b() of the class a will break if you don't declare $somevar
in the class definition. In the string "if (!isset($this->somevar))"
it would throw an error saying that you have no variable named 'somevar' in
you class.
