        [image] => data/imac_1.jpg
        [discount] =>

        [weight_class] => kg
    )

[40] => Array
    (
        [name] => iPhone
        [price] => 101.0000
        [image] => data/iphone_1.jpg
        [discount] => 
        [stock_status] => 
        [weight_class] => kg
    )
)

i need the sub array key (47 ,28 etc) as it is my product id

I'm running a foreach loop to get the details and assigning to a new array e.g. 'name' => $result['name'] but can't figure out how to target the product id.

Answer 1

You can assign the key to a variable in your foreach loop:

foreach($array as $id => $result) {
    $item = array('name' => $result['name'], 'id' => $id);
}
