Hello Reader's if you want to add two or more objects into one. Then you can see it into the example below:-

Ideally if you want the data to be together, you should have a parent class which has all these member functions and you should have a parent class with all common properties for every child, and each child has its own properties declared in it.

   $obj1 = new stdClass();
    $obj1->a = 'obj1:a';
    $obj1->b = 'obj1:b';
    $obj1->c = 'obj1:c';

    $obj2 = new stdClass();
    $obj2->a = 'obj2:a';
    $obj2->b = 'obj2:b';
    $obj2->d = 'obj2:d';

    $obj3 = new Compositor();
    $obj3->merge($obj1, $obj2);
    $obj1->c = '#obj1:c';
    var_dump($obj3->a, $obj3->b, $obj3->c, $obj3->d);
    // obj2:a, obj2:b, obj1:c, obj2:d
    $obj1->c;

    $obj3 = new Compositor(TRUE);
    $obj3->merge($obj1)->with($obj2);
    $obj1->c = '#obj1:c';
    var_dump($obj3->a, $obj3->b, $obj3->c, $obj3->d);
    // obj1:a, obj1:b, obj1:c, obj2:d
    $obj1->c = 'obj1:c';

    $obj3 = new Compositor(FALSE, TRUE);
    $obj3->with($obj1)->with($obj2);
    $obj1->c = '#obj1:c';
    var_dump($obj3->a, $obj3->b, $obj3->c, $obj3->d);
    // obj1:a, obj1:b, #obj1:c, obj2:d
    $obj1->c = 'obj1:c';
