本文实例为大家分享了PHP支付宝当面付2.0代码，供大家参考，具体内容如下
//支付宝条码支付，直接调用ali_tiaoma_pay方法，把条码和金额传进去就okfunction ali_tiaoma_pay($tiaoma,$price){ $data["scene"] = "bar_code"; //支付场景 $data["out_trade_no"] = date("Ymd").rand(10000,99999); //订单号 $data["total_amount"] = $price; //支付金额 $data["auth_code"] = $tiaoma; //支付授权码 $data["subject"] = "订单标题"; //订单标题 $data["body"] = "订单说明"; //订单说明 $data = json_encode($data); $params["app_id"] = $alipay_account; $params["method"] = "alipay.trade.pay"; $params["charset"] = "utf-8"; $params["sign_type"] = "RSA2"; $params["timestamp"] = date("Y-m-d H:i:s"); $params["version"] = "1.0"; $params["notify_url"] = ""; $params["biz_content"] = $data; ksort($params); //对将要签名的数组排序 $string = $this->toUrlParam($params); //将数组转换成字符串 $params["sign"] = $this->alipay_sign($string); //将字符串签名 $url = "https://openapi.alipay.com/gateway.do?" . http_build_query($params); $return = file_get_contents($url); //打开支付请求连接 获取二维码地址 $return = json_decode($return, true); //将返回的字符串转换为数组 return $return;} //app支付宝签名function alipay_sign($data, $signType = "RSA2") $res = "-----BEGIN RSA PRIVATE KEY-----" . wordwrap("你的商户私钥，必须和公匙匹配", 64, "", true) . "-----END RSA PRIVATE KEY-----"; ($res) or die("您使用的私钥格式错误，请检查RSA私钥配置"); if ("RSA2" == $signType) { openssl_sign($data, $sign, $res, "SHA256"); } else { openssl_sign($data, $sign, $res); } $sign = base64_encode($sign); return $sign;} /* * 格式化参数格式化成url参数*/function toUrlParam($param){ $buff = ""; foreach($param as $k => $v) { if($k != "sign" && $v != "" && !is_array($v)){ $buff .= $k."=".$v."&"; } } $buff = trim($buff, "&"); return $buff;}以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持网页设计。
