本文实例讲述了PHP微信支付功能。分享给大家供大家参考，具体如下：

微信开发SDK:文中用的是php_sdk_v3.0.9 ：https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1

import("wxpay.lib.AppPay#Config", EXTEND_PATH, ".php");import("wxpay.lib.WxPay#Api", EXTEND_PATH, ".php");//$this->weixinpay();$config = new \AppPayConfig();//订单号$appId = $config->GetAppId();$key = $config->GetKey();$money = 0.01 * 100;$orderSn = 'M201810241754107557';//订单号;$curTime = time();$input = new \WxPayUnifiedOrder();$input->SetBody("用户红包");$input->SetOut_trade_no($orderSn);$input->SetTotal_fee($money);$input->SetTrade_type("APP");$unifiedOrder = \WxPayApi::unifiedOrder($config, $input);if ($unifiedOrder['result_code'] == 'SUCCESS' && $unifiedOrder['return_code'] == 'SUCCESS') { /*$unifiedOrder 组成： * ["appid"] => string(18) "wx2xxxx49" ["mch_id"] => string(10) "1xxxxxx01" ["nonce_str"] => string(16) "1GnEUXTuTcFtJVtb" ["prepay_id"] => string(36) "wx241933xxx68fa24ece70611692955" ["result_code"] => string(7) "SUCCESS" ["return_code"] => string(7) "SUCCESS" ["return_msg"] => string(2) "OK" ["sign"] => string(32) "7903xxxxx4710E460CB156" ["trade_type"] => string(3) "APP"*/ $curTime = time(); // 第一部分 $wxpayResult = new \WxPayResults(); $wxpayResult->SetData('appid', $unifiedOrder['appid']); $wxpayResult->SetData('partnerid', $unifiedOrder['mch_id']); $wxpayResult->SetData('prepayid', $unifiedOrder['prepay_id']); $wxpayResult->SetData('noncestr', $unifiedOrder['nonce_str']); $wxpayResult->SetData('timestamp',$curTime); $wxpayResult->SetData('package',"Sign=WXPay"); $wxpayResult->SetData('sign',""); $wxpayResult->SetSign($config); $data = $wxpayResult->GetValues(); // 第二部分 $data['appid'] = $unifiedOrder['appid']; $data['partnerid'] = $unifiedOrder['mch_id']; $data['prepayid'] = $unifiedOrder['prepay_id']; $data['noncestr'] = $unifiedOrder['nonce_str'];; $data['timestamp'] = $curTime; $data['package'] = "Sign=WXPay"; $data['sign'] = $this->wxappPaySign($key, $data);//$unifiedOrder['sign'];//签名,具体签名方案参见微信公众号支付帮助文档; $this->returnSuccess($data);} else { Log::write(var_export($unifiedOrder, true)); $this->returnError(300, '微信支付失败');}private function wxappPaySign($key,$parameters){ $sign = md5(sprintf("appid=%s&noncestr=%s&package=%s&partnerid=%s&prepayid=%s&timestamp=%s&key=%s", $parameters['appid'], $parameters['noncestr'], $parameters['package'], $parameters['partnerid'], $parameters['prepayid'], $parameters['timestamp'], $key)); return strtoupper($sign);}

第一部分和第二部分功能是相同的。
