print xml response separately for each property - php

Question

I am trying to convert this XML to array this is the response I am getting from API and I want to get the value of statuscode but I am unable to do it.
<?xml version='1.0' encoding='utf-8' standalone='no'?>
<REGISTRATIONRESPONSE>
<STATUSCODE>20</STATUSCODE>
<STATUS>1234</STATUS>
</REGISTRATIONRESPONSE>
but when i am using the following code
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 6);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,'RequestData='.$post);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/x-www-form-urlencoded'));
$result = curl_exec($ch);
$resultres=xml2ary($result);
echo '<pre>';
print_r($resultres);
The output is
Array
(
[string] => Array
(
[_a] => Array
(
[xmlns] => http://tempuri.org/
)
[_v] => 201234
)
)
How is the result changing? I have used one more technique also but with that also I am not getting the result that is required

Have a look at SimpleXML
<?php
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 6);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,'RequestData='.$post);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/x-www-form-urlencoded'));
$result = curl_exec($ch);
/** #var SimpleXMLElement $xml */
$xml = simplexml_load_string($result);
// nice, use SimpleXMLElement object
var_dump($xml);
// not nice, use array instead
var_dump((array) $xml);
Just make sure the XML response you're getting from the API is the same you have posted above. Here it is again for reference:
<?xml version='1.0' encoding='utf-8' standalone='no'?>
<REGISTRATIONRESPONSE>
<STATUSCODE>20</STATUSCODE>
<STATUS>1234</STATUS>
</REGISTRATIONRESPONSE>
Here is an example without cURL, just add it to a file and run it from the terminal:
<?php
$xmlString = <<<XML
<?xml version='1.0' encoding='utf-8' standalone='no'?>
<REGISTRATIONRESPONSE>
<STATUSCODE>20</STATUSCODE>
<STATUS>1234</STATUS>
</REGISTRATIONRESPONSE>
XML;
$xml = simplexml_load_string($xmlString);
// everything
var_dump($xml);
// independent values
var_dump((string) $xml->STATUSCODE);
var_dump((string) $xml->STATUS);
// now with arrays
$array = (array) $xml;
// everything
var_dump($array);
// independent values
var_dump($array['STATUSCODE']);
var_dump($array['STATUS']);
// want to print it?
echo sprintf('Registration responded with status code %d and status %d', $xml->STATUSCODE, $xml->STATUS) . PHP_EOL;
echo sprintf('Registration responded with status code %d and status %d', $array['STATUSCODE'], $array['STATUS']) . PHP_EOL;

If the XML is coming through, for instance like so:
<class>
<type>
<input>Text</input>
<input>Text</input>
</type>
<type>
<input>Text</input>
<input>Text</input>
</type>
<type>
<input>Text</input>
<input>Text</input>
</type>
</class>
What you could do is:
$xml = simplexml_load_file("filepath");
$classes = $xml->$class;
foreach ($classes as $keyClass => $class) {
echo "<ul><li>Class</li><ul>";
$types = $class->type;
foreach ($types as $keyType => $type) {
echo "<li>Type</li><ul>";
$inputs = $type->input;
foreach ($inputs as $keyInput => $input) {
echo "<li>Input</li>";
}
echo "</ul>";
}
echo "</ul></ul>";
}
