How to Fix class not found in Laravel - php

Question

In Laravel I need to communicate to a 3rd party API. Thay have given me some PHP implementation (class) which I can use to connect and communicate with their API.
But when I try this as a class in a subfolder of the App folder and add this to my controller, I get a class not found error.
I have added a folder 'Qenner' (the provider of the API) in the App folder. And copied their classes in there.
In my controller I'm using these classes and add a code sample, like they send it to me.
Controller code (API-KEY is replaced with the actual key):
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Qenner\Search;
use QennerSearch\ServiceClient;
class TestController extends Controller
{
public function index() {
$search = new Search('https://search.qenner.com', 'API-KEY', true, 'nl-NL');
$response = $search->getCriteria([], ['Country'], []);
if (!$response->isError()) {
$criterionSets = $response->getCriterionSets();
$countryCriterionSet = criterionSets[0];
$countries = $countryCriterionSet->getCriteria();
$resultCount = $response->getResultCount();
}
dd($response);
}
Search.php in Qenner folder:
/**
* #file
* Contains QennerSearch\Search.
*/
namespace QennerSearch;
use QennerSearch\model\messages\CriterionTypesResponse;
use QennerSearch\model\messages\CriteriaRequest;
use QennerSearch\model\messages\CriteriaResponse;
use QennerSearch\model\messages\ErrorResponse;
use QennerSearch\model\messages\SearchRequest;
use QennerSearch\model\messages\SearchResponse;
use QennerSearch\model\messages\PriceRequest;
use QennerSearch\model\messages\PriceResponse;
use QennerSearch\model\messages\AccommodationInfoRequest;
use QennerSearch\model\messages\AccommodationInfoResponse;
use QennerSearch\model\messages\AutoCompleteRequest;
use QennerSearch\model\messages\AutoCompleteResponse;
/**
* Class Search, using ServiceClient to communicate, implementing the SearchInterface
*
* #package QennerSearch
*/
class Search extends ServiceClient implements SearchInterface {
.....
The folder has a ServiceClient.php
ServiceClient.php
/**
* #file
* Contains QennerSearch\Search.
*/
namespace QennerSearch;
use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;
/**
* Class Search.
*
* #package QennerSearch
*/
class ServiceClient {
protected $http_client = null;
protected $engine_url = null;
protected $api_key = null;
protected $log_calls = false;
protected $locale = null;
protected $last_result_code = 0;
protected $last_error_body = null;
public function __construct($engine_url, $api_key, $log_calls = false, $locale = "nl-NL") {
$this->http_client = new Client();
$this->engine_url = $engine_url;
$this->api_key = $api_key;
$this->log_calls = $log_calls;
$this->locale = $locale;
I get this error:
Class 'QennerSearch\ServiceClient' not found
While I expected a dump of the output

After seeing your folder structure in the comments, I believe ServiceClient.php and Search.php, both are inside the folder: app\Qenner, hence inside those files:
wherever you are using: namespace QennerSearch;
you should use: namespace App\Qenner;
and then inside your controller, instead of using: use QennerSearch\ServiceClient;
use: namespace App\Qenner\ServiceClient
Namespaces are not like aliases, they need to reflect the position of the file itself if that makes sense.
Please give it a try and let me know if it works.
