Problem calling class from the ProcessCallbackTask anonymous method

[gubi]

I have some errors with this piece of code:

class A {
    public function run($machine_name) {
        echo $machine_name;
    }
}


class B extends A {
    public static function listen() {
        $manager = new ProcessManager();
        $A = new A();
        foreach(self::get_devices() as $k => $machine) {
	    $task[$k] = new ProcessCallbackTask(function() use($k, $machine, $A) {
                A->run($machine->name); // No way
                $A->run($machine->name); // No way
            });
            $manager->addTask($task[$k]);
        }
	while($manager->tick()) {
	    usleep(250);
	}
    }
}

How to call A class method from ProcessCallbackTask in B class?

I would like to process async commands on a set of online machines, taken from db
Thanks in advance

$A = new A();
 foreach(self::get_devices() as $k => $machine) {
   $task[$k] = new ProcessCallbackTask(function() use($k, $machine, $A) {
   A->run($machine->name); // No way
   $A->run($machine->name); // No way
});

Just to let you know, there are problems with your code sample.

1. There is no need for $A = new A(); you have extended the class, the methods is now part of class B.
2. Since the methods of A are included/part of B, you need to reference like $this->run().
3. If you want to access class A directly you need to do A::run(); not A->run($machine->name);

I don't see how you code would run right under any conditions without those changes
