How to loop through a LinkedIn API response?

Question

I am retrieving connections via LinkedIn's API.

This is a sample of the response. All I want to do is loop through this using PHP, accessing first and last names. Should be simple, but I am stumped. Thanks.

stdClass Object ( [_total] => 420 [values] => Array ( [0] => stdClass Object ( [apiStandardProfileRequest] => stdClass Object ( [headers] => stdClass Object ( [_total] => 1 [values] => Array ( [0] => stdClass Object ( [name] => x-li-auth-token [value] => name:AnUY ) ) ) [url] => http://api.linkedin.com/v1/people/7yw8k_sjqf ) [firstName] => John [headline] => Finance Manager at ABC.

What you have as the response is an stdclass which will have all of its properties public.

This is how you iterate it:

$response = $this->getResponseFromLinkedIn();
foreach ($response->values as $value) {
    $firstName = $value->firstName;
    $lastName = $value->lastName;
    // do something with the extracted values!
}
