Cannot iterate over properties that are an array?

[ChangePlaces]

I'm trying to parse the GeteBayDetails response and convert all the CountryDetails to an array:

$payload['countryDetails'] = array_walk($resp->CountryDetails, function($x){return $x->toArray();});

Except the first $x is actually the whole countrydetails array - it instead iterates over the 5 elements of CountryDetails object instead of through them, so I get the error that I'm calling toArray on an array.

How can I actually do what I want to do?

CountryDetails is not a true array, but is "array like" in that it implements ArrayAccess, Countable, and Iterator.

For the most part you can treat it as a normally array. However, for some functions you need to first call iterator_to_array to convert it into a true array.

Also array_walk returns a boolean. I think you need to call array_map to get what you want.

$array = iterator_to_array($response->CountryDetails);
$results = array_map(function ($countryDetails) {
    return $countryDetails->toArray();
}, $array);

The above can also be reduced to a single line as the SDK supports JMESPath Expressions;

$results = $response->search('CountryDetails[]');
