Objects Within Objects in PHP

Objects Within Objects

You can use objects inside other objects in the same way as other variable types. For example, we could define a ATag class and give each A a ATag object like this:

class ATag {
            public $Words;
    }

    class A {
            public $Name;
            public $ATag;

            public function say( ) {
                    print "Hello!\n";
            }
    }

    // Definition of B...

Accessing objects within objects is as simple as using -> again:
    $p = new B;
    $p->Name = "p";
    $p->ATag = new ATag;
    $p->ATag->Words = "My name is P. If you find me, please call  1234";

The $ATag property is declared like any other, but needs to be created with new once $p has been created.
