Question

class Car {


    function __construct() {
//        echo 'car con';
    }

    function setInfo($car_arr) {
            foreach ($car_arr as $key => $value) {
                $this->{$key} = $value;
            }

    }

}

i try to access like bellow

$car1 = new Car();
$car1->setInfo('make', 'Toyota')->setInfo('model', 'scp10');

that gave to me bellow error

Call to a member function setInfo() on a non-object

how can i change setInfo() method call $car1->setInfo('make', 'Toyota')->setInfo('model', 'scp10'); after that car class set $make = 'Toyota', like that

how can i print this object like bellow

make = Toyota
model = scp10

You need to add return $this; in the end of your method for chain-like calls.
