Question

<?phpclass Staff{ private $name; private $age; private $salary; public function _construct($name,$age,$salary) { $this->name=$name; $this->age=$age; $this->salary=$salary; } public function _get($name) { return $this->$name; }}$obj=new Staff('peter',18,4000);echo $obj->name;echo $obj->age;?>

Answer 1

If you want to output $name, you must use the public function _get method. Private is a private variable and cannot be called externally.

Answer 2

The properties in the Staff class are defined as private and can only be called within the class. Change them to public and solve the problem
