Something is wrong here, what am I mssing? Why is the output at width4 not 4?
Output : width1: 4 width2: 4 width3: 4 width4: 20
Expected: width1: 4 width2: 4 width3: 4 width4: 4

<?php
$mytest = new MyTestClass(4, 5);
echo " width4: ".$mytest->$int_width;
class MyTestClass {
public $int_width;
public $int_height;
public $int_area;
public function __construct($int_width, $int_height){
$this->my_new_test($int_width, $int_height);
echo " width3: ".$this->$int_width;
}
function my_new_test($int_width, $int_height){
$this->$int_width = $int_width;
$this->$int_height = $int_height;
echo " width1: ".$this->$int_width;
$this->$int_area = $int_width * $int_height;
echo " width2: ".$this->$int_width;
