支付宝网站支付php代码,php支付宝系列之电脑网站支付

网上的很多PHP支付宝支付接入教程都颇为复杂，且需要配置和引入较多的文件，本人通过整理后给出一个单文件版的，希望可以给各位想接入支付宝支付的带来些许帮助和借鉴意义。

一个PHP文件搞定支付宝系列

一个PHP文件搞定微信支付系列

环境依赖

PHP5.0以上，且需要开启CURL服务、SSL服务。

注意事项

1.文件开头的配置信息必须完善

2.商户私钥需填写对应签名算法类型的私钥，如何生成密钥参考：

2.1 生成RSA密钥

2.2 创建应用

代码

header('Content-type:text/html; Charset=utf-8');

$appid = 'xxxxx'; //https://open.alipay.com 账户中心->密钥管理->开放平台密钥，填写添加了电脑网站支付的应用的APPID

$returnUrl = 'http://www.xxx.com/alipay/return.php'; //付款成功后的同步回调地址

$notifyUrl = 'http://www.xxx.com/alipay/notify.php'; //付款成功后的异步回调地址

$outTradeNo = uniqid(); //你自己的商品订单号

$payAmount = 0.01; //付款金额，单位:元

$orderName = '支付测试'; //订单标题

$signType = 'RSA2'; //签名算法类型，支持RSA2和RSA，推荐使用RSA2

//商户私钥，填写对应签名算法类型的私钥，如何生成密钥参考：https://docs.open.alipay.com/291/105971和https://docs.open.alipay.com/200/105310
