将XML元素转换为数组

好吧,假设你想要一个

array(
    1 => array(
        'Value 1',
        'Value 2',
    )
)

假设一个

<root>
    <Data>
        <!-- key and column entities -->
    </Data>
    <Data>
        <!-- key and column entities -->
    </Data>
    <Data>
        <!-- key and column entities -->
    </Data>
</root>

你可以这样做(我更喜欢) DomDocument ):

$dom = new DomDocument();
$dom->loadXml($xmlString);
$dataElements = $dom->getElementsByTagName('Data');
$array = array();
foreach ($dataElements as $element) {
    $subarray = array();
    foreach ($element->childNodes as $node) {
        if (!$node instanceof DomElement) {
            continue;
        }
        $key = $node->tagName;
        $value = $node->textContent;
        $subarray[$key] = $value;
    }
    $array[] = $subarray;
}

通过编辑,它将变成:

<root>
    <Data>
        <Key>4</Key>
        <Foo>Bar</Foo>
    </Data>
    <Data>
        <Key>6</Key>
        <Bar>Baz</Bar>
    </Data>
</root>

分为:

array(
    array(
        'Key' => 4,
        'Foo' => 'Bar',
    ),
    array(
        'Key' => 6,
        'Bar' => 'Baz',
    ),
)

SimpleXML是您要搜索的库的名称: http://php.net/manual/en/book.simplexml.php
