PHP Looping over Nested Array [duplicate]

Question

I have an array which looks like this:

I'm trying to loop over this and extract the values for groupAssetID and groupAssetName in the data array but haven't been able to get this to work so far. I've tried:

    foreach ( $records as $record) {
        echo $field . ": " . $value . "<br />\r\n" ;
    }

and

     foreach ( $records->fieldData as $field=>$value) {
        echo $field . ": " . $value . "<br />\r\n" ;
    }

but none of these seem to work and I can't work out the correct syntax here.

I managed it to run with this syntax:

$records = array
(
    'response' => array
        (
            'dataInfo' => array
                (
                    'totalRecordCount' => 362,
                    'foundCount' => 5,
                    'returnedCount' => 5
                ),

            'data' => array
                (
                    0 => array
                        (
                            'fieldData' => array
                                (
                                    'groupAssetID' => 1020,
                                    'groupAssetName' => 'Standard Equipment'
                                ),

                            'portalData' => array
                                (
                                ),

                            'recordId' => 823,
                            'modId' => 1
                        ),

                    1 => array
                        (
                            'fieldData' => array
                                (
                                    'groupAssetID' => 1001,
                                    'groupAssetName' => 'Tools'
                                ),

                            'portalData' => array
                                (
                                ),

                            'recordId' => 829,
                            'modId' => 1
                        ),

                    2 => array
                        (
                            'fieldData' => array
                                (
                                    'groupAssetID' => 1005,
                                    'groupAssetName' => 'Spare Parts'
                                ),

                            'portalData' => array
                                (
                                ),

                            'recordId' => 830,
                            'modId' => 1
                        )
                )
        ),

    'messages' => array
        (
            0 => array
                (
                    'code' => 0,
                    'message' => 'OK'
                )
        )
);

foreach ($records['response']['data'] as $key => $value) {
        
    echo $value['fieldData']['groupAssetID'] . ": " . $value['fieldData']['groupAssetName'] . "<br />\r\n" ;
}

Output:

1020: Standard Equipment
1001: Tools
1005: Spare Parts
