while($this->change >= 0){
$this->change - 50;
$this->counter++;
}
You will need to actually set $this->change
instead of just performing a subtraction. You can do $this->change -= 50;

I've incremented the loop and looked it over a good amount of times. The loop should just break when $change goes below 0, yet it loops forever until it exceeds the maximum time of 30 seconds. I'm a beginner, so I'd appreciate some help please.
<?php
class change{
private $cash = 0;
private $change = 0;
private $price = 0;
private $counter = 0;
public function setPrice($setPrice){
$this->price = $setPrice;
}
public function setCash($setCash){
$this->cash = $setCash;
}
public function getChange(){
$this->change = ($this->cash - $this->price);
while($this->change >= 0){
$this->change - 50;
$this->counter++;
}
return $this->counter;
}
}
$newChange = new change;
$newChange->setCash(600);
$newChange->setPrice(200);
$newChange->getChange();
?>
