Question

在PHP中使用simplexml_file_load后，我尝试使用我在Php.NET（http://www.php.net/manual/en/ref.simplexml.php）中找到的一些代码（XmlToArray（））将xml转换为数组，以便我可以处理响应然后执行将其发布到给定的URL。

但是，XML文档中定义的顺序不是我在执行print_r（数组）时在终端中显示数组的方式。

有没有办法维护数组中XML中列出的相同顺序？任何帮助/方向将不胜感激。

这是我的机器本地的xml：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

这是我从PHP.net中选择的XMLToArray（）：

function XMLToArray($xml)
{
    if ($xml instanceof SimpleXMLElement) {
        $children = $xml->children();
        $return = null;
    }

    foreach ($children as $element => $value) {
        if ($value instanceof SimpleXMLElement) {
            $values = (array) $value->children();

            if (count($values) > 0) {
                $return[$element] = XMLToArray($value);
            } else {
                if (!isset($return[$element])) {
                    $return[$element] = (string) $value;
                } else {
                    if (!is_array($return[$element])) {
                        $return[$element] = array($return[$element], (string) $value);
                    } else {
                        $return[$element][] = (string) $value;
                    }
                }
            }
        }
    }

    if (is_array($return)) {
        return $return;
    } else {
        return $false;
    }
}

提前致谢。问候。

当我测试提供的代码时，我发现它与你提供的xml片段工作正常，但是如果添加其他项目，例如它在数组输出中丢失了它们。

我可以建议您尝试使用这个功能，而不是调试功能，这似乎对我有用：

来自Frederic 2008 @ Source of code sample

/**
 * Parse a SimpleXMLElement object recursively into an Array.
 * Attention: attributes skipped
 *
 *
 * @param $xml The SimpleXMLElement object
 * @param $arr Target array where the values will be stored
 * @return NULL
 */
private function convertXmlObjToArr( $obj, &$arr )
{
    $children = $obj->children();
    $executed = false;
    foreach ($children as $elementName => $node)
    {
        if( array_key_exists( $elementName , $arr ) )
        {
            if(array_key_exists( 0 ,$arr[$elementName] ) )
            {
                $i = count($arr[$elementName]);
                $this->convertXmlObjToArr ($node, $arr[$elementName][$i]);    
            }
            else
            {
                $tmp = $arr[$elementName];
                $arr[$elementName] = array();
                $arr[$elementName][0] = $tmp;
                $i = count($arr[$elementName]);
                $this->convertXmlObjToArr($node, $arr[$elementName][$i]);
            }
        }
        else
        {
            $arr[$elementName] = array();
            $this->convertXmlObjToArr($node, $arr[$elementName]);   
        }
        $executed = true;
    }
    if(!$executed&&$children->getName()=="")
    {
        $arr = (String)$obj;
    }

    return ;
}
