Changing keys in new nested array

Question

So I am trying to assign different keys to my array. I have the initial array and then I remove the duplicates and the concat the id's of the duplicates into the one array. What I dont understand is why the keys of my arrays are the same as my fields

This is the current output of my array. Also for some reason, it is adding an empty array at the end and I dont know why.

Array
(
    [0] => Array
        (
            [4.2GHz quad-core Intel Core i7 Turbo Boost up to 4.5GHz] => Array
                (
                    [field] => 4.2GHz quad-core Intel Core i7 Turbo Boost up to 4.5GHz
                    [product_id] => 156 157
                )

            [3.4GHz quad-core Intel Core i5 Turbo Boost up to 3.8GHz] => Array
                (
                    [field] => 3.4GHz quad-core Intel Core i5 Turbo Boost up to 3.8GHz
                    [product_id] => 158
                )

        )

    [1] => Array
        (
            [1TB SSD] => Array
                (
                    [field] => 1TB SSD
                    [product_id] => 156
                )

            [2TB SSD] => Array
                (
                    [field] => 2TB SSD
                    [product_id] => 157
                )

            [1TB Fusion Drive] => Array
                (
                    [field] => 1TB Fusion Drive
                    [product_id] => 158
                )

        )

    [2] => Array
        (
        )

)

This is my code.

$categories = array();
$new_values = array();

foreach($recs as $key => $rec){
    if($rec['processors']) {
        $categories['processors']['fields'][] = array('field' => $rec['processors'], 'product_id' => $rec['product_id']);
    }
    if($rec['storage']) {
        $categories['storage']['fields'][] = array('field' => $rec['storage'], 'product_id' => $rec['product_id']);
    }
    if($rec['memory']) {
        $categories['memory']['fields'][] = array('field' => $rec['memory'], 'product_id' => $rec['product_id']);
    }
    if($rec['graphics']) {
        $categories['graphics']['fields'][] = array('field' => $rec['graphics'], 'product_id' => $rec['product_id']);
    }
    if($rec['colors']) {
        $categories['colors']['fields'][] = array('field' => $rec['colors'], 'product_id' => $rec['product_id']);
    }
}

foreach($categories as $key => $fields) {
    foreach($fields['fields'] as $field) {
        if (isset($new_values[$key][$field['field']])) {
            $temp = $new_values[$key][$field['field']];
            $temp['product_id'] .= ' ' . $field['product_id'];
            $new_values[$key][$field['field']] = $temp;
        } else {
            if($field['field']) {
                $new_values[$key][$field['field']] = $field;
            }
        }
    }
}

$new_values = array_values($new_values);

This is the array I am trying to accomplish with what I am doing. I have some idea on doing it by using $key in my loop but I cannot quite narrow it down.

Array
(
    [processors] => Array
        (
            [0] => Array
                (
                    [field] => 4.2GHz quad-core Intel Core i7 Turbo Boost up to 4.5GHz
                    [product_id] => 156 157
                )

            [1] => Array
                (
                    [field] => 3.4GHz quad-core Intel Core i5 Turbo Boost up to 3.8GHz
                    [product_id] => 158
                )

        )

    [storage] => Array
        (
            [0] => Array
                (
                    [field] => 1TB SSD
                    [product_id] => 156
                    [type] => storage
                )

            [1] => Array
                (
                    [field] => 2TB SSD
                    [product_id] => 157
                )

            [2] => Array
                (
                    [field] => 1TB Fusion Drive
                    [product_id] => 158
                )

        )
)

Any suggestions is greatly appreciated.

You are using array_values() on the top level in...

$new_values = array_values($new_values);

and not in the level underneath (the actual item names)...

foreach($new_values as $key => $fields) {
    $new_values[$key] = array_values($fields);
}
