$response = curl_exec($ch);
curl_close($ch);
dd($response);
It is of type response string.
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<ns3:GetProductListResponse xmlns:ns3="http://xxx1">
<result>
<status>success</status>
</result>
<products>
<product>
<currencyAmount>900.00</currencyAmount>
<currencyType>1</currencyType>
<displayPrice>900.00</displayPrice>
<isDomestic>false</isDomestic>

To convert this data to xml I used simplexml_load_string()
$response = curl_exec($ch);
curl_close($ch);
$xml = simplexml_load_string($response);
dd($xml);
And the output is like this.
^ SimpleXMLElement {#435}
I'm trying to access the data in it and try this.
$status = (string)$xml->result->status;
dd($status);
Returns :
^ ""
I tried using simplexml_load_file() and got no results. My main goal is to get this data as json, but I can't do it because I can't read the values.Any help would be great. Thanks in advance.
After #Jacob Mulquin's suggestion I used:
if ($xml === false) {
dump("b");
foreach (libxml_get_errors() as $error) {
dump($error->message);
}
dd("a");
} else {
dd("c");
}
Returned : "c"

Your sample xml is not well formed, for various reasons, but assuming that the actual $response is a well formed xml string, the following should get you what you need:
#first you need to deal with namespaces
$xml->registerXPathNamespace("ns3", "http://xxx1");
#then use xpath to select your target element
$status = $xml->xpath('//ns3:GetProductListResponse//status')[0];
echo $status;
Output should be
success
