The content of this article is about the callback asynchronous processing process of WeChat payment in PHP. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

WeChat payment callback processing is divided into

Here WeChat officially recommends using the second

php to handle WeChat callback asynchronously

//获取返回的xml
$testxml  = file_get_contents("php://input");
//将xml转化为json格式
$jsonxml = json_encode(simplexml_load_string($testxml, 'SimpleXMLElement', LIBXML_NOCDATA));
//转成数组
$result = json_decode($jsonxml, true);
if($result){
          //如果成功返回了
         if($result['return_code'] == 'SUCCESS' && $result['result_code'] == 'SUCCESS'){
          //进行改变订单状态等操作。。。。 
   }
}

The xml returned by WeChat payment this time is converted into json format as follows:

{
    "appid": "12345",
    "attach": "pay",
    "bank_type": "CFT",
    "cash_fee": "1",
    "fee_type": "CNY",

    "trade_type": "MWEB",
    "transaction_id": "4200000171201808221550954201"
