php Function method

这篇文章主要介绍了PHP 接入支付宝即时到账功能,非常不错,具有参考借鉴价值,需要的朋友可以参考下

首先请到支付宝那边申请一个及时到账的接口账户,需要提交相关材料申请。然后根据即时到账的API文档进行接入。API文档提供了各种语言版本的demo,我这里是下的php版demo,然后再进行相关修改操作。你也可以将demo版本的代码重新整合,我这里暂时为了走通充值及时到账流程,就不进行代码重构了。

API文档:https://doc.open.alipay.com/docs/doc.htm?spm=a219a.7386797.0.0.eZb8FX&treeId=108&articleId=103950&docType=1
