How to get values ​​from json array?

Question

PHP

There is an API. I get a response from him in a json array using curl_init ();
I check the answer like this:

$resp = json_decode($response, true);
print_r ($resp);

I see this:
Array ( [success] => 1 [data] => Array ( [0] => Array ( [Number] => 20400091908900 [DateCreated] => 19-06-2018 00:00:00 [DocumentWeight] = > 1.75 [CheckWeight] => 0 [DocumentCost] => 66 [SumBeforeCheckWeight] => 0 [PayerType] => Recipient [RecipientFullName] => [RecipientDateTime] => [OwnerDocumentType] => [ScheduledDeliveryDate] => 22-06- 2018 [PaymentMethod] => Cash [CargoDescriptionString] => [CargoType] => Parcel [CitySender] => Kherson [CityRecipient] => Stanytsia Lugansk [WarehouseRecipient] => Warehouse #3....I won't give the whole text ()
So, I don't understand how to extract values ​​by keys, I
tried
echo $resp->DateCreated;
or
echo $resp['DateCreated']; - with and without quotes.
As I understand it, there are still many nested arrays. Tried to parse them foreach();
But just as ineffective. To be honest, I didn’t work with json and I don’t understand how it builds an array. I've been trying for two days with no results. Help me please! Thank you.

foreach ($resp['data'] as $i => $row) {
    echo $row['DateCreated'];
}
