SimpleXML Attributes to Array
提问by mseancole
Is there any more elegant way to escape SimpleXML attributes to an array?
有没有更优雅的方法将 SimpleXML 属性转义到数组？
$result = $xml->xpath( $xpath );
$element = $result[ 0 ];
$attributes = (array) $element->attributes();
$attributes = $attributes[ '@attributes' ];
I don't really want to have to loop through it just to extract the key/value pair. All I need is to get it into an array and then pass it on. I would have thought attributes()would have done it by default, or at least given the option. But I couldn't even find the above solution anywhere, I had to figure that out on my own. Am I over complicating this or something?
我真的不想为了提取键/值对而遍历它。我所需要的只是将它放入一个数组中，然后将其传递。我原以为attributes()默认情况下会这样做，或者至少可以选择。但是我什至无法在任何地方找到上述解决方案，我不得不自己解决这个问题。我是不是把这件事复杂化了？
Edit:
编辑：
I'm still using the above script until I know for sure whether accessing the @attributes array is safe or not.
我仍在使用上述脚本，直到我确定访问 @attributes 数组是否安全为止。

Don't directly read the '@attributes'property, that's for internal use. Anyway, attributes()can already be used as an array without needing to "convert" to a real array.
不要直接读取'@attributes'属性，这是供内部使用的。无论如何，attributes()已经可以用作数组而无需“转换”为真正的数组。
For example:
例如：
<?php
$xml = '<xml><test><a a="b" r="x" q="v" /></test><b/></xml>';
$x = new SimpleXMLElement($xml);
$attr = $x->test[0]->a[0]->attributes();
echo $attr['a']; // "b"
If you want it to be a "true" array, you're gonna have to loop:
如果你希望它是一个“真正的”数组，你将不得不循环：
$attrArray = array();
$attr = $x->test[0]->a[0]->attributes();
foreach($attr as $key=>$val){
$attrArray[(string)$key] = (string)$val;
}

a more elegant way; it gives you the same results without using $attributes[ '@attributes' ]:
更优雅的方式；它在不使用$attributes[ '@attributes' ] 的情况下为您提供相同的结果：
$attributes = current($element->attributes());

You could convert the whole xml document into an array:
您可以将整个 xml 文档转换为一个数组：
$array = json_decode(json_encode((array) simplexml_load_string("<response>{$xml}</response>")), true);

For me below method worked
对我来说，下面的方法有效
function xmlToArray(SimpleXMLElement $xml)
{
$parser = function (SimpleXMLElement $xml, array $collection = []) use (&$parser) {
$nodes = $xml->children();
$attributes = $xml->attributes();
if (0 !== count($attributes)) {
foreach ($attributes as $attrName => $attrValue) {
$collection['@attributes'][$attrName] = strval($attrValue);
}
}
if (0 === $nodes->count()) {
if($xml->attributes())
{
$collection['value'] = strval($xml);
}
else
{
$collection = strval($xml);
}
return $collection;
}
foreach ($nodes as $nodeName => $nodeValue) {
if (count($nodeValue->xpath('../' . $nodeName)) < 2) {
$collection[$nodeName] = $parser($nodeValue);
continue;
}
$collection[$nodeName][] = $parser($nodeValue);
}
return $collection;
};
return [
$xml->getName() => $parser($xml)
];
}
This also provides me all the attributes as well, which I didn't get from any other method.
这也为我提供了所有属性，这是我没有从任何其他方法中获得的。

I think you will have to loop through. You can get it into array once you read xml.
我想你将不得不循环。读取xml后，您可以将其放入数组。
<?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;
}
$xmlStr = file_get_contents($xml_file);
$xmlObj = simplexml_load_string($xmlStr);
$arrXml = objectsIntoArray($xmlObj);
foreach($arrXml as $attr)
foreach($attr as $key->$val){
if($key == '@attributes') ....
}
