我现在需要遍历每个发票并从每张发票中提取一些数据。余可使用计数发票的总数：

$totalInvoices = count($invoices->Invoices[0]);

返回6.我然后试图使用foreach循环从每个发票抢[InvoiceNumber]值如下：

$recnum = 0; 

foreach($invoices as $invoice){ 
    $invoiceNumber = $invoices->Invoices[0]->Invoice[$recnum]->InvoiceNumber; 

    $recnum++; 
}

，但它只返回前5个InvoiceNumbers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，所以我可能会在这里丢失一些东西，但它看起来很喜欢普通的PHP数组。

更新：我已经更新了循环如下：

// 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++; 
    }

，这是在输出浏览器进行以下（过大的身体，包括这里）：

它似乎有麻烦最后2发票和解析数组？

回声$ invoiceNumber在循环发票只显示5？尝试在循环print_r（$ invoice）中添加此行;显示什么？ – cosmoonot

@cosmoonot我已经更新了这个问题。我认为这提供了一个线索，但不知道在这里做什么？解析这种类型的数组可能的问题？ – user982124

试试这个foreach循环，希望它能在提取发票信息时正常工作。

PHP code demo

总没有。

$numberOfInvoices=count($invoiceObject->Invoices->Invoice);

提取发票的信息：

foreach($invoiceObject->Invoices->Invoice as $invoiceObj) 
{ 
    echo "Invoice Number: ".$invoiceObj->InvoiceNumber; 
    echo "Invoice Status: ".$invoiceObj->Status; 

}

我没有得到任何输出 - $ numberOfInvoices也返回0。 – user982124

@ user982124我的文章的循环工作吗？ –

没有没有在浏览器中得到任何输出 – user982124

我认为，这是最简单的方式来实现自己的目标：

$invoiceNumbers = array(); 
    foreach($invoices->Invoices->Invoices as $invoice){ 
     $invoiceNumbers[] = $invoice->InvoiceNumber; 
    } 
    echo "<pre>"; 
    print_r($invoiceNumbers);

我刚刚在浏览器中运行时出现以下情况： Array （） – user982124

PHP循环遍历结果并解析出值
