"userCode": "123456-FErKS5yu15scpSGmvip4JA==",
"demands": {
"demand": {
"result": {
"answers": {
"answer": [{
"text": "Yes",
"id": "23123124",
"total": "1074",
"percent": "89.13"
}, {
"text": "No",
"id": "23123125",
"total": "131",
"percent": "10.87"
}]
}, "id": "690432265"
}, "id": "GetPollResults"
}
}
}
}

First we have to decode the json data. so we use json_decode. Then we select the right element and loop through it to get all the anwers
$data = '{ "pdResponse": { "partnerGUID": "3F2504E0-4F89-11D3-9A0C-0305E82C3301", "userCode": "123456-FErKS5yu15scpSGmvip4JA==", "demands": { "demand": { "result": { "answers": { "answer": [{ "text": "Yes", "id": "23123124", "total": "1074", "percent": "89.13" }, { "text": "No", "id": "23123125", "total": "131", "percent": "10.87" }] }, "id": "690432265" }, "id": "GetPollResults" } } } }';
$response = json_decode($data);
$answers = $response->pdResponse->demands->demand->result->answers->answer;
foreach($answers as $a)
{
echo $a->total;
}
