PHP SimpleXML - 多个 children 同名

Question

我目前正在使用以下 php 代码生成一个 xml 文件。它采用表单输入并将它们放入 xml 文件中。

我想要多个 children 同名。例如：

<person>
  <address>
    <street>streetname</street>
    <streetnumber>streetnumber</streetnumber>
  </address>
  <address>
    <street>streetname</street>
    <streetnumber>streetnumber</streetnumber>
  </address>
</person>

我生成 xml 的代码遵循此结构；

//Add first address - working

$xml->person = "";
$xml->person->address = "";

$xml->person->address->addChild('streetname', $_POST['streetname1']);
$xml->person->address->addChild('streetnumber', $_POST['streetnumber1']);


//Attempt to add second address, doesn't work

$xml->person->address = "";

$xml->person->address->addChild('streetname', $_POST['streetname2']);
$xml->person->address->addChild('streetnumber', $_POST['streetnumber2']);

Answer 1

在构建 XML 文档时使用变量会更容易、更简洁。然后你可以像这样将多个 <address> 元素添加到你的 <person> 元素...

$person = $xml->addChild('person');

$address1 = $person->addChild('address');
$address1->addChild('streetname', $_POST['streetname1']);
$address1->addChild('streetnumber', $_POST['streetnumber1']);

$address2 = $person->addChild('address');
$address2->addChild('streetname', $_POST['streetname2']);
$address2->addChild('streetnumber', $_POST['streetnumber2']);
