XML 响应转换为数组

Question

XML 响应想要转换为 PHP 数组，它在 $response 中可以正常工作，但是当我转换为数组时，它将变为空。如何将此 XML 转换为数组以在网页上显示？任何能指引我正确方向的信息都会很棒。

$soapUrl = "http://api.rlcarriers.com/1.0.2/RateQuoteService.asmx"; // asmx URL of WSDL
    $xml_post_string = '<?xml version="1.0" encoding="utf-8"?>

        $headers = array(
        "Content-type: text/xml;charset=\"utf-8\"",
        "Accept: text/xml",
        "Cache-Control: no-cache",
        "Pragma: no-cache",
        "SOAPAction: http://www.rlcarriers.com/GetRateQuote", 
        "Content-length: ".strlen($xml_post_string),
        ); //SOAPAction: your op URL

        $url = $soapUrl;

        // PHP cURL  for https connection with auth
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        //curl_setopt($ch, CURLOPT_USERPWD, $soapUser.":".$soapPassword); // username and password - declared at the top of the doc
        curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
        curl_setopt($ch, CURLOPT_TIMEOUT, 10);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string); // the SOAP request
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

        // converting
        $response = curl_exec($ch); 
        curl_close($ch);
        var_dump($response);exit;

        $xml = simplexml_load_string($response);
        $json = json_encode($xml);
        $array = json_decode($json,TRUE);
        print_r($array);

以下是从上述代码收到的响应。

这些是 SOAP XML，将其标题更改为

... // 转换 $response = curl_exec($ch); curl_close($ch); $clean_xml = str_ireplace(['SOAP-ENV:', 'SOAP:'], '', $response); $xml = simplexml_load_string($clean_xml); $json = json_encode($xml); $array = json_decode($json,TRUE); print_r($array);
