It sounds like your only other option is a singleton, which works only if
you're comfortable having only one instance of a, ever. The following code
also only works in PHP 5.
class A {
static obj;
static instance() {
if (! self::obj instanceof A) {
self::obj = new A();
}
return self::obj;
}
}
class B {
function print() {
$a = A::instance();
$a->print();
}
}
(Possibly a syntax error in the above, but hopefully you get the idea.)

"If nature has made any one thing less susceptible than all others of
exclusive property, it is the action of the thinking power called an idea,
which an individual may exclusively possess as long as he keeps it to
himself; but the moment it is divulged, it forces itself into the possession
of every one, and the receiver cannot dispossess himself of it." -- Thomas
