"status": "completed",
"total_btc": {

},
"total_native": {
"cents": 1253,
"currency_iso": "USD"
},
"custom": "order1234",
"receive_address": "1NhwPYPgoPwr5hynRAsto5ZgEcw1LzM3My",
"button": {
"type": "buy_now",
"name": "Alpaca Socks",
"description": "The ultimate in lightweight footwear",

},
"transaction": {

如何检索“美分”或任何其他变量的值?
答案 0 :(得分:2)
您需要使用json_decode()
解码它
$json = json_decode($jsonString);
那将为您提供一个对象,然后您可以像这样使用它
echo $json->order->total_btc->cents;

试试这个,
// let
$jsondata='{order:{...}}';
$json = json_decode($jsondata,true);
echo $json['order']['total_native']['cents'];
答案 2 :(得分:0)
取决于您如何处理传入的数据。
正如Dave Chen所说,使用$_POST['order']['total_native']['cents']
,但您需要先解码它们,在特定的$ _POST索引上使用json_decode()
。
然后,选择是否需要数组或对象:
$json_obj = json_decode($string);
将返回stdClass
个对象。要获取数据,请使用此$json_obj->total_btc->cents
但是,这个:
$json_arr = json_decode($string, true);
将返回一个数组,您可以在其中获取$json_arr['order']['total_native']['cents']

发送
$data_string = json_encode(array("customer"=>array("key"=>"val")));
$data_string = urlencode(json_encode($data));
curl_setopt($ch, CURLOPT_POSTFIELDS, array("customer"=>$data_string));
收到它
$datastring = $_POST['customer'];
$data = json_decode( urldecode( $datastring));
