segregating php object variables - php

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
(
[0] => Array
(
[id] => 14301
[origination] => outgoing
[start_time] => 2011-06-17 13:40:58
[from] => CALLER_NAME <4485>
[from_account_id] => 1120
[from_name] => CALLER_NAME
[from_number] => 4485
[to] => CALLEE_NAME <6534>
[to_account_id] => 1101
[to_name] => CALLEE_NAME
[to_number] => 6534
[total_duration] => 47
[talk_duration] => 43
[events] => Array
(
[event] => Array
(
[0] => Array
(
[start_time] => 2011-06-17 13:40:58
[type] => OUTGOING
[display] => Dialed number (6534)
)
[1] => Array
(
[start_time] => 2011-06-17 13:40:58
[type] => INTERNAL
[display] => Rang CALLEE_NAME <6534>
)
[2] => Array
(
[start_time] => 2011-06-17 13:41:02
[type] => TALKING
[display] => Talked to CALLEE_NAME <6534> for 43 seconds
)
[3] => Array
(
[start_time] => 2011-06-17 13:41:45
[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'];

Answer 2

All three properties are marked private, so they would have to be obtained through accessor methods marked public
