I have created a few classes and they have some dependencies on each other. I’m wondering if what I have created is considered acceptable.

Here is an example with 3 classes (A, B, C).

• Class A is dependent on Class B and C.

• Class B is dependent on Class A.

• Class C has no dependencies.

class A {
    function __construct() {}
    public function init($dependencies) {
        foreach($dependencies as $name => $dependency) {
            $this->{$name} = $dependency;
        }
    }
    public function foo() {
        if($this->B->bar()) {
            return 'A via B is true';
        }
        if($this->C->bar()) {
            return 'C true';
        }
        return false;
    }
    public function bar() {
        return true;
    }
}

class B {
    function __construct() {}
    public function init($dependencies) {
        foreach($dependencies as $name => $dependency) {
            $this->{$name} = $dependency;
        }
    }
    public function bar() {
        if($this->A->bar()) {
            return true;
        }
        return false;
    }
}

class C {
    function __construct() {}
    public function bar() {
        return true;
    }
}

$A = new A();
$B = new B();
$C = new C();

$A->init(array(
    'B' => $B,
    'C' => $C
));
$B->init(array(
    'A' => $A
));

var_dump($A->foo());

Thanks!
