将xml转换为数组，输出不需要的数组

发布于 2024-11-17 00:15:08 字数 371 浏览 4 评论 0原文

我正在尝试将 xml 转换为关联数组。

  foreach($xml->children() as $child)
  {
  $ages[$child->getName()] = $child;
  }

但是，当我打印出这个数组“年龄”时，我得到的输出是“

[Quagmire] => SimpleXMLElement Object
        (
            [0] => 30
        )

我

[Quagmire] => 30

要做什么改变才能获得所需的输出？”

I am trying to convert xml into associative array.

  foreach($xml->children() as $child)
  {
  $ages[$child->getName()] = $child;
  }

But when I print out this array 'ages', I am getting output as

[Quagmire] => SimpleXMLElement Object
        (
            [0] => 30
        )

instead of

[Quagmire] => 30

What change do I make to get the desired output?

您可以将子项的值从 SimpleXML 对象显式转换为 int。

    $ages[$child->getName()] = (int)$child;

You can explicitly cast the value of the child from a SimpleXML object to an int.

    $ages[$child->getName()] = (int)$child;

是的，SimpleXML 对象的问题在于它们不完全是对象。它们实际上是资源。这就是您遇到此问题的原因。几年前，当我尝试序列化 XML 对象以供以后使用时，我遇到了这个问题。

您需要做的是编写一个执行转换的函数。现在通常我会写一个出来，但事实证明 PHP 社区中的许多人已经解决了这个问题并将其发布在 php.net 网站上。

下面的代码来自 http://www.php.net/manual/ en/book.simplexml.php#97555

<?php
function objectsIntoArray($arrObjData, $arrSkipIndices = array())
{
  $arrData = array();

  // if input is object, convert into array
  if (is_object($arrObjData))
    $arrObjData = get_object_vars($arrObjData);

  if (is_array($arrObjData))
  {
    foreach ($arrObjData as $index => $value)
    {
      if (is_object($value) || is_array($value))
        $value = objectsIntoArray($value, $arrSkipIndices); // recursive call

      if (in_array($index, $arrSkipIndices))
        continue;

      $arrData[$index] = $value;
    }
  }

  return $arrData;
}
?>

Usage:

<?php
$xmlUrl = "feed.xml"; // XML feed file/URL
$xmlStr = file_get_contents($xmlUrl);
$xmlObj = simplexml_load_string($xmlStr);
$arrXml = objectsIntoArray($xmlObj);
print_r($arrXml);
?>

上面的代码被我稍微清理了一下。我对丑陋的代码感到恼火。不管怎样，尝试一下，祝你好运！

Yeah the problem with SimpleXML Objects is that they are not entirely objects. They are actually resources. Which is why you run into this issue. I ran into this a few years ago when I was trying to serialize an XML object for later use.

What you need to do is write a function that will do the convert. Now normally I would write one out, but it turns out a number of people in the PHP community have already tackled this problem and posted it on the php.net website.

The below code comes from http://www.php.net/manual/en/book.simplexml.php#97555

<?php
function objectsIntoArray($arrObjData, $arrSkipIndices = array())
{
  $arrData = array();

  // if input is object, convert into array
  if (is_object($arrObjData))
    $arrObjData = get_object_vars($arrObjData);

  if (is_array($arrObjData))
  {
    foreach ($arrObjData as $index => $value)
    {
      if (is_object($value) || is_array($value))
        $value = objectsIntoArray($value, $arrSkipIndices); // recursive call

      if (in_array($index, $arrSkipIndices))
        continue;

      $arrData[$index] = $value;
    }
  }

  return $arrData;
}
?>

Usage:

<?php
$xmlUrl = "feed.xml"; // XML feed file/URL
$xmlStr = file_get_contents($xmlUrl);
$xmlObj = simplexml_load_string($xmlStr);
$arrXml = objectsIntoArray($xmlObj);
print_r($arrXml);
?>

The code above was slightly cleaned up by me. I get annoyed by ugly code. Anyway, give that a crack and good luck!
