tp5 处理xml 数据

//xml请求方法

public function docommon($url,$data){
    $ch = curl_init();
    $timeout = 30;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, 1);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//Post提交的数据包
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

//$arr 为请求到的数据

$arr = $this->docommon($url,$data);
// 使用domdocument 来操作xml

// 解析xml类
$dom->loadXML($arr);
// 处理xml数据

$zarr=getArray($dom->documentElement);

//xml 转为array
