I have an array:

Array (
    [variants] => Array ( 
        [0] => Array (
            [barcode] => 610373772697
            [compare_at_price] =>
            [created_at] => 2015-06-27T01:56:42-07:00
            [fulfillment_service] => manual
            [grams] => 190
            [id] => 3856358467
            [inventory_management] => shopify
            [inventory_policy] => deny
            [option1] => Default Title
            [option2] =>
            [option3] =>
            [position] => 1

            [inventory_quantity] => 100
            [old_inventory_quantity] => 100
            [image_id] =>
            [weight] => 0.42
            [weight_unit] => lb
        ) 
        [1] => Array (
            [barcode] => 364031530906
            [compare_at_price] =>

            [weight] => 0.29
            [weight_unit] => lb

        ) 
        [2] => Array (
            [barcode] => 364031534003
            [compare_at_price] =>

            [fulfillment_service] => manual
            [grams] => 390
            [id] => 3856359107
            [inventory_management] => shopify
            [inventory_policy] => deny
            [option1] => Default Title
            [option2] =>
            [option3] =>
            [position] => 1
            [price] => 27.74
            [product_id] => 1259973123
            [requires_shipping] => 1
            [sku] => 0116368
            [taxable] => 1
            [title] => Default Title
            [updated_at] => 2015-06-27T01:56:43-07:00
            [inventory_quantity] => 100
            [old_inventory_quantity] => 100
            [image_id] =>
            [weight] => 0.86
            [weight_unit] => lb
        )
    )
) 
) 

And no matter how many For Loops I try, I cannot figure out how to extract the [id] and the [product_id] and pass them to variables using PHP.

My goal is to dump the id and product_id into a mysql database and I once I get the values out I can do that easily.

Can anyone help guide me?
