new to OOP, quick help

[Eggzorcist]

I've made my first object that will addition an array but it doens't seem to be working as it echo's out 0.

 

here is my script

<?php

class A {
public $sum = 0;

function addition($values){

	foreach ($values as $numbers){
		$this->sum = $number + $this->sum;
	}

	echo $this->sum;
}


}

$a = new A();

$array = array(10, 15, 25);

echo $a->addition($array);

?>

 

I don't see what I'm doing wrong. Any direction would be greatly appreciated.

Missing an s on the $numbers variable where you perform the addition, outside of that, a couple of things.

 

It's generally bad practice to explicitly echo out values in your functions, since you do that you could display your answer without the echo in the call.

 

But really, you should set inside the function to "return $this->sum;", and then keep your call the same.

 

So I quickly switched it to:

class A {
public $sum = 0;

function addition($values){

	foreach ($values as $number){
		$this->sum += $number;
	}

	return $this->sum;
}


}

$a = new A();

$array = array(10, 15, 25);

echo $a->addition($array);
