How to access a PHP variable from one function in another function - php

Question

I have already written an application in a procedural way and am trying to move into into a Laravel framework. I'm having trouble with the SOAP exchange section as I am getting an ID value that authenticates the user but cannot access that value (as a cookie) later in the program to authenticate the search.
Here is my code so far:
<?php namespace App;
use Artisaninweb\SoapWrapper\Facades\SoapWrapper;
use Illuminate\Http\RedirectResponse;
class SoapController {
private $auth_response;
private $cookie;
private $search_client;
private $search_response;
public function soapExchange() {
// create SOAP client and add service details
SoapWrapper::add(function ($service) {
$service
->name('WoSAuthenticate')
->wsdl('http://search.webofknowledge.com/esti/wokmws/ws/WOKMWSAuthenticate?wsdl')
->trace(true)
->cache(WSDL_CACHE_NONE);
});
SoapWrapper::service('WoSAuthenticate', function($service) {
// call authenticate() method to get SID cookie
$auth_response = $service->call('authenticate', []);
$cookie = $auth_response->return;
// test for cookie return
// print($cookie);
});
// create SOAP client and add service details
$search_client = new SoapWrapper;
$search_client::add(function ($service) {
$service
->name('WoSSearch')
->wsdl('http://search.webofknowledge.com/esti/wokmws/ws/WokSearch?wsdl')
->trace(true)
->cache(WSDL_CACHE_NONE);
});
if (isset($auth_response->return)) {
// if there is an SID returned then add it to the cookie attribute of the search client
$search_client->__setCookie('SID', $cookie);
} else {
// route to relevant view to display throttle error
return redirect('throttle');
}
}
}
I am successfully retrieving the response from the Web API call and getting a code to authenticate the user, saved as $cookie. However, I need then to create another SoapWrapper for performing the search and this needs the ID code attached by using the __setCookie method. If nothing is returned by the authenticate call then it redirects to an error message via throttle.blade.php elsewhere.
Surely there is a way to return a value created from a function so that it can be used elsewhere?
** EDIT **
Looked into employing SoapClient instead and including all operations within a single function. It all relates to a specific Web API anyway so I guess separation of concerns is not so much of an issue. FYI the new class I am trying is this:
<?php namespace App\Models;
use SoapClient;
use Illuminate\Http\RedirectResponse;
class SoapWrapper {
public function soapExchange() {
// set WSDL for authentication and create new SOAP client
$auth_url = "http://search.webofknowledge.com/esti/wokmws/ws/WOKMWSAuthenticate?wsdl";
// array options are temporary and used to track request & response data
$auth_client = #new SoapClient($auth_url);
// set WSDL for search and create new SOAP client
$search_url = "http://search.webofknowledge.com/esti/wokmws/ws/WokSearch?wsdl";
// array options are temporary and used to track request & response data
$search_client = #new SoapClient($search_url);
// run 'authenticate' method and store as variable
$auth_response = $auth_client->authenticate();
// call 'setCookie' method on '$search_client' storing SID (Session ID) as the response (value) given from the 'authenticate' method
// check if an SID has been set, if not it means Throttle server has stopped the query, therefore display error message
if (isset($auth_response->return)) {
$search_client->__setCookie('SID',$auth_response->return);
} else {
return Redirect::route('throttle');
}
}
}

Answer 1

Maybe try $GLOBALS?
<?php
$GLOBALS[data] = "something";
function abc(){
echo $GLOBALS[data];
}
?>

Answer 2

use Artisaninweb\SoapWrapper\Facades\SoapWrapper;
class SoapController extends Controller {
public $resultSoapStatus;
public $resultSoapAuthority;
public function heySoap{
SoapWrapper::add(function ($service) ...
$data = [
'MerchantID' => $MerchantID,
'Amount' => $Amount,
'Description' => $Description,
'Email' => $Email,
'Mobile' => $Mobile,
'CallbackURL' => $CallbackURL
];
SoapWrapper::service('test', function ($service) use ($data) {
$resultSoap = $service->call('PaymentRequest', [$data]);
$this->resultSoapStatus = $resultSoap->Status;
$this->resultSoapAuthority = $resultSoap->Authority;
});
if($this->resultSoapStatus == 100 && strlen($this->resultSoapAuthority) == 36)
{
//Do Something
}
else
{
return Redirect::back();
}
}
}
