Sure, but there was a mistake in your example - Closure::current(10)
should be Closure::current()(10), i.e. "get the current closure, and
then immediately invoke it, passing 10".
More readable if you put it in a local variable:
$a = function (int $numberA) {
$b = function (int $numberB) {
$selfReference = Closure::getCurrent();
if($numberB < 10) {
return $selfReference(10);
}
return $numberB;
};
return $b($numberA) + $numberA;
};
var_dump($a(4));
The local var $selfReference refers to the same Closure object as the
outer var $b, because that's the closure that's "current" on the line
where Closure::getCurrent() is called.
