Question

I have some XML that is being returned to be as an object, like this:

SwitchvoxResponse Object
(
[apiStatus:private] => success
[apiErrors:private] => Array
    (
    )

[apiResult:private] => Array
    (
        [calls] => Array
            (
                [page_number] => 1
                [total_pages] => 1
                [items_per_page] => 50
                [total_items] => 1
                [call] => Array
                    (

                                                    )

                                                    )

                                                [2] => Array
                                                    (
                                                        [start_time] => 2011-06-17 13:41:02
                                                        [type] => TALKING
                                                        [display] => Talked to CALLEE_NAME <6534> for 43 seconds
                                                    )

                                                [3] => Array

                                                        [type] => HANGUP
                                                        [display] => Call was hung up by CALLER_NAME <4485>
                                                    )

                                            )

                                    )

                            )
                    )
            )
    )
)

How do I pull out the values of these variables?

Answer 1

The results can be accessed via the SwitchvoxResponse::getResult() method. Given $object is the SwitchvoxResponse object quoted in the question, the example below loops over each call and prints the from values.

$result = $object->getResult();
foreach ($result['calls']['call'] as $call) {
    echo $call['from'];
}

Similarly, the response status is fetched via $object->getResponseStatus() and any errors via $object->getErrors().

The response statuses can be one of SV_RESPONSE_SUCCESS, SV_RESPONSE_FAULT or SV_RESPONSE_FAILED.

Edit re. comments

To get the items for the first call only, simply do:

$result = $object->getResult();
$call = $result['calls']['call'][0];
// And access the values like
echo $call['from_name'];
