[SOLVED] How to solve undefined variable and undefined property warnings?

Issue

I have $name and $age defined in set_name() and set_age.
Please check index.php:

<?php
// This part needs some fixing.
class Pet {
    public $name;
    public $age;    

    // get() and set() functions for name
    function set_name($name) {
        $this->name = $name;
    }
    function get_name() {
        return $this->$name;
    }

    // get() and set() functions for age
    function set_age($age) {
        $this->age = $age;
    }
    function get_age() {
        return $this->$name;
    }
}
.....

Edit:
This problem is fixed. No need for new answers!

Solution

You need constructor for your classes and don’t do the makeSound method in your Pet class static. Try this:

public Cat(){
  makeSound(sound);
}

public Dog(){
  makeSound(sound);
}
