Loop through an array in PHP

Question

Is there a way to refer to a value of an array inside of an aray?

For example.

I have the following php code to loop through an array listed below. Can I easily get the [product_name] => DIESEL #2 data without another for loop? If I know the data will always come this way? Something like $fuel = $value['transaction_id'.'product'.'product_name']?

foreach ($result['data'] as $key => $value) {
    $id =  $value['id'];
    $transactionId =  "FC".$value['transaction_id'];
    $transactionDateTime = $value['created_utc'];
    echo $id." - ".$transactionDateTime." - ".$transactionId." </br>";


}



(
    [data] => Array
        (
            [0] => Array
                (
                    [id] => 5750574
                    [label] => 
                    [self] => https://api.fuelcloud.com/rest/v1.0/transaction/5750574
                    [transaction_id] => 0025621e-3270-c0e2-8d2a-6425ed834f9d
                    [transaction_type] => 1
                    [tank_id] => 23744
                    [start_date] => 2019-12-19T00:00:00
                    [end_date] => 2019-12-19T23:59:59Z
                    [site_id] => 23743
                    [product_id] => 409
                    [product] => Array
                        (
                            [id] => 409
                            [product_name] => DIESEL #2
                            [product_category] => diesel
                        )

$fuel = $value['product']['product_name']; is it what you are loooking for? — Akash Kumar

You already know how to reference array entries, it seems, like $value['id']. $value['product'] is another array, and $value['product']['product_name'] is the value of the product_name key from that array.

I feel so stupid. TY. I don't code in PHP full time. Looks like a simple syntax issue on my part.
