How to implement Alipay transfer payment in php

In recent years, mobile payment has become a part of people’s lives. When you are shopping quickly or traveling, Alipay has become your fastest and most convenient payment method. Here we will introduce how to make payment through Alipay transfer.

Alipay transfer is a safe and smooth payment method that not only meets the transfer needs between individuals, but also facilitates merchants’ daily transactions and brings many conveniences to life.

To implement Alipay transfer, you need to use php and the payment interface of Alipay open platform. The following are the specific implementation steps:

First you need to select an API interface that supports Alipay transfers. The transfer interface of Alipay's open platform can easily complete transfer operations. Developers need to apply for a merchant number first and call the corresponding interface according to the interface document to perform transfer operations.

With the help of php language, we can easily call the transfer interface of Alipay open platform. The following is a php code example:

<?php
    //引入支付宝 SDK 文件，实现转账功能
    require_once("alipay-sdk-PHP-20161101/AopSdk.php");

    //构建 aliPaySdk 对象
    $aliPaySdk = new AopClient();

    //设置沙箱环境参数，设置为 true 时为测试环境
    $aliPaySdk->gatewayUrl = 'https://openapi.alipaydev.com/gateway.do';

    //设置签名方式
    $aliPaySdk->signType = 'RSA2';

    //设置应用 ID
    $aliPaySdk->appId = '当前应用的 AppId';

    //设置商户私钥
    $aliPaySdk->rsaPrivateKey = '商户私钥';

    //获取转账参数
    $bizContent = array(
        'out_biz_no' => '转账单号', // 商家单据号
        'payee_type' => 'ALIPAY_LOGONID', // 收款账户类型，支付宝登录账户：ALIPAY_LOGONID
        'payee_account' => '转账账号', // 收款账户，如支付宝账号
        'amount' => '转账金额', // 转账金额，单位：元
        'payer_show_name' => '付款方，可以为备注或者公司名', // 付款方, 如备注或者公司名
        'payee_real_name' => '收款人真实姓名', //收款人的真实姓名
        'remark' => '转账备注', // 转账备注
    );

    //转账
    $result = $aliPaySdk->execute ( new \AlipayFundTransToaccountTransferRequest(), $bizContent );

    //输出转账结果
    echo '<pre class="brush:php;toolbar:false">' . print_r($result,true) . '

'; ?>

With the above code, we can easily implement the transfer function based on Alipay. When making transfers, you need to pay attention to the following matters:

1. The merchant number and application ID need to be applied on the open platform. For specific methods, please refer to the relevant documents of the Alipay open platform.
2. Ensure the accuracy of transfer information. Especially the account information of the receiving account, if there is an error, there may be a risk of transfer failure.
3. The transfer amount depends on the actual situation of the receivable account. An amount that is too high may cause the transfer to fail, and an amount that is too low may not meet the actual demand.
