Connecting to metadata API in SOAP with token in PHP

Question

I try to call retrieve in SOAP using PHP but I need to login before. For login, I have a token that I get from "https://test.salesforce.com/services/oauth2/token"

So, I try to pass this token in the header of my SOAP request

    $wsdl = PUBLIC_PATH . '/wsdl-metadata.xml'; // le fichier wsdl

    $apiVersion = 44.0;
    $singlePackage = true;
    $members = 'ServiceSetting.' . $service;
    $name = 'customMetadata';

    $params = new StdClass();
    $params->retrieveRequest = new StdClass();
    $params->retrieveRequest->apiVersion = $apiVersion;
    $params->retrieveRequest->singlePackage = $singlePackage;
    $params->retrieveRequest->unpackaged = new StdClass();
    $params->retrieveRequest->unpackaged->version = $apiVersion;
    $params->retrieveRequest->unpackaged->type = new stdClass();
    $params->retrieveRequest->unpackaged->type->members = $members;
    $params->retrieveRequest->unpackaged->type->name = $name;

    $option = [
        'trace' => TRUE,
    ];
    // Namespaces
    $namespace = 'http://soap.sforce.com/2006/04/metadata';
    $client = new SoapClient($wsdl, $option);

    $header = new SoapHeader($namespace, "SessionHeader", array ('sessionId' => $token));
    $client->__setSoapHeaders($header);
    $serviceResult = $client->retrieve($params);

The Error is

UNKNOWN_EXCEPTION: Destination URL not reset. The URL returned from login must be set in the SforceService

You need more than just a session ID; you also need the correct endpoint. The default endpoint in the SOAP client is only for logging in. When you get a token (or session ID), you'll have a serverUrl attribute. You'll need to store this so you can set it later, something like:

$client->setEndPoint($serverUrl);
