Version Mismatch in PHP SOAP Call - php

Question

I'm trying to make a soap call to a server with as little code as possible. But I'm alreaty having issues authenticating myself (No headers neccessary for that call). This is the code I have:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
header('Content-Type: text/html; charset=utf-8');
$data = array('Username' => 'someusername', 'Userpass' => 'somepass');
try
{
$client = new SoapClient(null, array(
"location" => "http://relaxdays.plentymarkets-x1.com/plenty/api/soap/version115/?xml",
"uri" => "http://relaxdays.plentymarkets-x1.com/plenty/api/soap/version115/",
"trace" => true,
"soap_version" => SOAP_1_1,
"exceptions" => false
));
$response = $client->__soapCall("PlentySoapRequest_GetAuthentificationToken", $data);
}
catch (Exception $e)
{
echo "Error!";
echo $e -> getMessage();
echo '<br/><br/>Last response:<button type="button" onclick="if(document.getElementById(\'spoiler1\').style.display==\'none\') {document.getElementById(\'spoiler1\') .style.display=\'\'}else{document.getElementById(\'spoiler1\') .style.display=\'none\'}">Show/Hide</button><div id="spoiler1" style="display:none; font-family:monospace;">'. htmlspecialchars($client->__getLastResponse()).'</div>';
}
echo '<br/><br/>Last request:<button type="button" onclick="if(document.getElementById(\'spoiler2\').style.display==\'none\') {document.getElementById(\'spoiler2\') .style.display=\'\'}else{document.getElementById(\'spoiler2\') .style.display=\'none\'}">Show/Hide</button><div id="spoiler2" style="display:none; font-family:monospace;">'. htmlspecialchars($client->__getLastRequest()).'</div>';
echo '<br/><br/>Response:<button type="button" onclick="if(document.getElementById(\'spoiler3\').style.display==\'none\') {document.getElementById(\'spoiler3\') .style.display=\'\'}else{document.getElementById(\'spoiler3\') .style.display=\'none\'}">Show/Hide</button><div id="spoiler3" style="display:none; font-family:monospace;">'. htmlspecialchars($response).'</div>';
?>
However, regardless of what I try, it doesn't seem to work. The furthest I've come is this error:
SoapFault exception: [VersionMismatch] Wrong Version in /var/www/htdocs/plentyimport/tester.php:18
Stack trace: #0 /var/www/htdocs/plentyimport/tester.php(18): SoapClient->__soapCall('PlentySoapReque...', Array) #1 {main}
I've already tried using "soap_version" => SOAP_1_2, or switching the Soap-URL to different versions (eg. /version112/) but the error just does not want to go away.
Any help would be appreciated.
Thank you very much

You have to pass the definition of SOAP as first parameter, like this:
$client = new SoapClient('http://relaxdays.plentymarkets-x1.com/plenty/api/soap/version115/?xml');
I have stripped other arguments as those are not required for making this work.
The call should be made to operation, in this case like this:
$response = $client->__soapCall("GetAuthentificationToken", $data);
An finally, the data should contain structure PlentySoapRequest_GetAuthentificationToken, like this:
$data = [
'PlentySoapRequest_GetAuthentificationToken' => [
'Username' => 'someusername',
'Userpass' => 'somepassword'
]
];
Note: I'm not posting this as complete answer. I don't know SOAP and can't explain what was wrong and how I fixed it, only posting this to help author get out of this phase.
