How can I extract a PHP string from this sub-array?

Question

The array I am looking at is this:

Array
(
[0] => Array
    (
        [0] => Bigcommerce\Api\Resources\ProductCustomField Object
            (
                [ignoreOnCreate:protected] => Array
                    (
                        [0] => id
                        [1] => product_id
                    )

                [ignoreOnUpdate:protected] => Array
                    (
                        [0] => id
                        [1] => product_id
                    )

                [fields:protected] => stdClass Object
                    (
                        [id] => 17
                        [product_id] => 3232
                        [name] => Artist
                        [text] => Test
                    )

                [id:protected] => 17
                [ignoreIfZero:protected] => Array
                    (
                    )

            )

    )

)

I want to check to see if 'Artist' exists in a php conditional statement. But I don't know how to turn 'Artist' into a string.

UPDATED: I did not find understand how to extract that value into a string, but I got what I was looking for using the method related to the bigcommerce api:

$customs = Bigcommerce::getProductCustomFields($product->id);
foreach($customs as $custom) {
if($custom->name == 'Artist'): // do something 
endif;
}

Answer 1

Ok, looking at the source, it seems you should be able to use the magic __get method. Try

$array[0][0]->name == 'Artist'

Answer 2

The value of the custom field would be stored in the "text" resource for that custom field.

See the following link where you can see the 4 properties of a custom field. https://developer.bigcommerce.com/api/stores/v2/products/custom_fields
