php语言 对接建行商户下单支付接口 httpsyunbusinessccbcomclp_ordertxCtrlserver php 代码完整示例

以下是一个使用PHP语言对接建行商户下单支付接口的代码示例：

<?php

// 商户号
$merId = 'YourMerchantId';
// 商户柜台代码
$posId = 'YourPosId';
// 分行代码
$branchId = 'YourBranchId';
// 订单号
$orderId = 'YourOrderId';
// 订单金额（单位：分）
$orderAmount = '100';
// 币种
$currency = '01';
// 交易码
$txCode = '530550';
// 版本号
$version = '5.0.0';
// 接入类型
$accessType = '0';
// 商户接收支付结果通知地址
$backUrl = 'YourNotifyUrl';
// 签名方法
$signMethod = 'MD5';
// 加密方法
$encryptMethod = 'RSA';
// 业务类型
$bizType = '000202';
// 商品信息
$goodsName = 'YourGoodsName';
// 商品数量
$goodsNum = '1';
// 用户IP
$clientIp = 'YourClientIp';
// 订单超时时间
$orderTimeout = '30';

// 请求参数

请注意，上述代码只是一个示例，其中的签名逻辑和发送请求的代码需要根据实际情况进行修改。另外，还需要根据建行商户下单支付接口的具体参数要求，将示例代码中的YourMerchantId、YourPosId、YourBranchId、YourOrderId、YourNotifyUrl、YourGoodsName、YourClientIp等字段替换为实际的值
