使用sepa- XML -php将数据导出到xml

<?php
// 创建一个新的 SimpleXMLElement 实例
$xml = new SimpleXMLElement('<?xml version="1.0" encoding="UTF-8"?><Document xmlns="urn:iso:std:iso:20022:tech:xsd:pain.001.001.03"><CstmrCdtTrfInitn></CstmrCdtTrfInitn></Document>');

// 添加根元素下的子元素
$initiation = $xml->CstmrCdtTrfInitn;
$groupHeader = $initiation->addChild('GrpHdr');
$groupHeader->addChild('MsgId', '123456789');
$groupHeader->addChild('CreDtTm', date('Y-m-d\TH:i:s'));
$groupHeader->addChild('NbOfTxs', '1');
$groupHeader->addChild('CtrlSum', '1000.00');

$paymentInfo = $initiation->addChild('PmtInf');
$paymentInfo->addChild('PmtInfId', '987654321');
$paymentInfo->addChild('PmtMtd', 'TRF');
$paymentInfo->addChild('ReqdExctnDt', date('Y-m-d'));

$debtorAccount = $paymentInfo->addChild('DbtrAcct');
$debtorAccount->addChild('Id', 'DE12345678901234567890');
$debtorAccount->addChild('Nm', 'John Doe');

$creditorAccount = $paymentInfo->addChild('CdtTrfTxInf');
$creditorAccount->addChild('CdtrAcct');
$creditorAccount->CdtrAcct->addChild('Id', 'FR98765432109876543210');
$creditorAccount->CdtrAcct->addChild('Nm', 'Jane Smith');

$creditorAccount->addChild('InstdAmt', '1000.00');
$creditorAccount->InstdAmt->addAttribute('Ccy', 'EUR');

// 保存 XML 文件
$xml->asXML('sepa_payment.xml');

echo "SEPA XML 文件已生成并保存为 sepa_payment.xml";
