现在，我需要遍历每个发票并从每个发票中提取一些数据。 我可以使用以下方法计算发票总数：
$totalInvoices = count($invoices->Invoices[0]);
它返回6。然后，我尝试使用foreach循环从每个发票中获取[InvoiceNumber]值，如下所示：
$recnum = 0;
foreach($invoices as $invoice){
$invoiceNumber = $invoices->Invoices[0]->Invoice[$recnum]->InvoiceNumber;
$recnum++;
}
但它只返回前5个InvoiceNumber，而不是第6个/最后一个（IV2023）。 我之前没有使用过这种类型的数据，因此我可能在这里丢失了一些东西，但它看起来像一个普通的PHP数组。
更新：我已如下更新循环：
// Loop through each invoice
$recnum = 0;
foreach($invoices as $invoice){
$invoiceNumber = $invoices->Invoices[0]->Invoice[$recnum]->InvoiceNumber;
echo '$invoiceNumber for $recnum '.$recnum.' is: '.$invoiceNumber.'<br>';
pr($invoice);
echo '<hr>';
/*
if (isset($_SESSION['DebugMode']) && $_SESSION['DebugMode'] == 'TRUE') {
pr($invoice);
}
*/
$recnum++;
}
并在浏览器中输出以下内容（太大，无法包含在此处）：

最后两张发票和解析数组似乎有问题？

试试这个foreach循环，希望它在提取发票信息时能正常工作。
总数 发票数：
$numberOfInvoices=count($invoiceObject->Invoices->Invoice);
提取发票信息：
foreach($invoiceObject->Invoices->Invoice as $invoiceObj)
{
echo "Invoice Number: ".$invoiceObj->InvoiceNumber;
echo "Invoice Status: ".$invoiceObj->Status;
}

我认为，这是实现目标的最简单方法：
$invoiceNumbers = array();
foreach($invoices->Invoices->Invoices as $invoice){
$invoiceNumbers[] = $invoice->InvoiceNumber;
}
echo "<pre>";
print_r($invoiceNumbers);
遍历结果并汇总并吐出php
