How to pass an array into a function, and return the results with an array

Question

So I\'m trying to learn how to pass arrays through a function, so that I can get around PHP\'s inability to return multiple values. Haven\'t been able to get anything to work so

Answer 1

i know a Class is a bit the overkill

class Foo
{

 private $sum = NULL;

 public function __construct($array)
 {
   $this->sum[] = $array;
   return $this;
 }

 public function getSum()
 {
   $sum = $this->sum;
   for($i=0;$igetSum();
