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。

扫码支付,指用户打开支付宝钱包中的“扫一扫”功能,扫描商家展示在某收银场景下的二维码并进行支付的模式。该模式适用于线下实体店支付、面对面支付等场景。
运行以下php文件代码即可生成一张付款二维码图片,使用支付宝扫一扫即可付款。
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
