class::variable - is this possible? (+)

[crimaniak]

Sometimes it is useful to refer to functions and variables in base classes or to refer to functions in classes that have not yet any instances. The :: operator is being used for this.

(C) PHP Manual

class test
{
var $a=1;
function f()
{
return 2;
}
}

Ok, I can call f:
echo test::f();

But how can I get default value for $a?
Or it's possible only for base classes?

You can't get the value of $a because $a is an instance variable, and since there's no instance of class test, $a is not defined. Maybe if you make $a a static variable it'll work, but then your class would work differently.
