PS. : when I trie to access like this it returns Null

$registrant->reasonPhrase

Answer 1

Well, In PHP, you can not access private property outside the class. You can access protected property in the subclasses of a class. But if they are needed to access by clients/you (meaning who is using the object/code) developers of that kind of classes use getters and setters method to access them. So you can use them as the following if you need them.

$registrant->getResponse()->getResponse()->getReasonPhrase();

Actually this method comes from this Guzzle's class GuzzleHttp\Psr7\Response. If you want you can find it here

Answer 2

To inspect the private properties of your MacsiDigital\Zoom\Support\Response Obj, you have no choice but using setter/getter methods.

Try

dump($registrant->getResponse());

Then

dump(($registrant->getResponse())->getReasonPhrase());
