print_r($variable); or $query="update tblname ..."

It doesn't work and it give me error

Really no idea what your asking. There is no chaining and the two snippets don't have any correlation. — AbraCadaver, Apr 16 '20 at 20:56
`->` is used with objects, not arrays. You need to define a class. — Barmar, Apr 16 '20 at 20:58

You are mixing some things up here I guess.

// Array syntax
$array = [];
$array['key'] = 'value'; // adding "value" to the array with the key "key"
$array['key'] = 'newValue'; // Values can be changed like this.

// Object syntax
$obj = new stdClass;
$obj->key = 'value'; // adding "value to the object with as the attribute "key"

BUT this would just be for a standard Class. When you are using an already existing class (in your example "Model") you can not always access or change the attributes. That's why you can often see methods like

$obj->getName(); //to get the value of "name" of the class
$obj->setName(); // to set...

Getter and Setter? I did a quick search. I think the link should clear up a couple of things. And for your code:

// option 1, create a class with getter and setter, see link
// option 2
$variable = new stdClass;
$variable->name = "Jack";
...
