Looping through array contain 3 classes

I am having trouble getting my head around how to loop through stdClasses.

Printing the array gives me the following:

Array
(
    [piggyback] => Array
        (
            [0] => stdClass Object
                (
                    [id] => 1003
                    [entity_id] => 0
                    [redirect_url] => http://yahoo.com
                    [type] => Image
                )

        )

    [total_count] => 1
)
Array
(
    [piggyback] => Array
        (
            [0] => stdClass Object
                (
                    [id] => 1002
                    [entity_id] => 0
                    [redirect_url] => http://google.com
                    [type] => Image
                )

        )

    [total_count] => 1
)
Array
(
    [piggyback] => Arra开发者_如何学Cy
        (
            [0] => stdClass Object
                (
                    [id] => 1001
                    [entity_id] => 0
                    [redirect_url] => http://bing.com
                    [type] => Image
                )

        )

    [total_count] => 1

I am trying to loop though with the following and print out a value (id) but I keep getting nothing.

foreach ($piggies_array as $key => $value) {
  echo $piggies_array[$key]['id'];
}

foreach ($piggies_array as $key => $value) {
if (is_array($value)){
  echo $value[0]->id;
 }
}

I think you need:

for ($i = 0; $i < count($piggies_array); $i++) {
    echo $piggies_array[$i]['piggyback'][0]->id;
}

...assuming we can only see part of your output ;)

try replace it to echo $value->id;
