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 [price] => 20.99 [product_id] => 1259972867 [requires_shipping] => 1 [sku] => 1125442 [taxable] => 1 [title] => Default Title [updated_at] => 2015-06-27T01:56:42-07:00 [inventory_quantity] => 100 [old_inventory_quantity] => 100 [image_id] => [weight] => 0.42 [weight_unit] => lb ) 
    [1] => Array 
        ( [barcode] => 364031530906 [compare_at_price] => [created_at] => 2015-06-27T01:56:42-07:00 [fulfillment_service] => manual [grams] => 131 [id] => 3856359043 [inventory_management] => shopify [inventory_policy] => deny [option1] => Default Title [option2] => [option3] => [position] => 1 [price] => 17.24 [product_id] => 1259973059 [requires_shipping] => 1 [sku] => 0116350 [taxable] => 1 [title] => Default Title [updated_at] => 2015-06-27T01:56:42-07:00 [inventory_quantity] => 100 [old_inventory_quantity] => 100 [image_id] => [weight] => 0.29 [weight_unit] => lb ) 
    [2] => Array 
        ( [barcode] => 364031534003 [compare_at_price] => [created_at] => 2015-06-27T01:56:43-07:00 [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?
