PHP xml转数组

方法一、
$xml = new DOMDocument();
        $xml->loadXML($xml);
        $array = array(
            'ToUserName'=>$xml->getElementsByTagName('ToUserName')->item(0)->nodeValue,
            'FromUserName'=>$xml->getElementsByTagName('FromUserName')->item(0)->nodeValue,
            'CreateTime'=>$xml->getElementsByTagName('CreateTime')->item(0)->nodeValue,
        );

方法二、

function getXmlData($xml){
        $array = [];
        $ex=explode('><![CDATA[',$xml);
        foreach($ex as $iex){
            $ie=explode('><',$iex);
            $vals = explode(']]',$ie[0]);
            if(count($vals)>=2){
                $val = $vals[0];
            }
            if(isset($ie[1]) && isset($val)){
                $keys = explode('/',$ie[1]);
                if(isset($keys[1])){
                    $array[$keys[1]] = $val;
                }
            }
        }
        return $array;
}
