Multidimensional Arrays in PHP
How do i add items into a multidimensional array? Basically i am making an application which calculates what people are buying in a suppermarket and how much of it. 

> Sue buys 2 tubs of butter and 1.
> toothpaste
> 
> John buys 1 peach and 1 banana.

I think the array would look something like this

    $sue[butter] = array(); 
    $sue[butter][] = 2;
    $sue[toothpaste] = array(); 
    $sue[toothpaste][] = 1;
    $john[peach] = array(); 
    $john[peach][] = 1;
    $john[banana] = array(); 
    $john[banana][] = 1;

My current code can only record the item and the item quantity.

	
	public $items = array();
	
	public function AddItem($product_id)
	{
		if (array_key_exists($product_id , $this->items))
		{
			$this->items[$product_id] = $this ->items[$product_id] + 1;
		} else {
			$this->items[$product_id] = 1;
		}
	}

I just dont know how to put this inside an array for each person.

Thanks!
