I am getting below error, while using quickbook online PHP sdk integration. Now I am trying to call the companyInfo API through the below sample code. But every time I stuck with the error "include(string.php)" not found. Any quick help would be greatly appreciated.
Here is my code :
$dataService = new DataService($this->serviceContext);
if (!$dataService)
exit("Problem while initializing DataService.
");
$allCompanies = $dataService->FindAll('CompanyInfo');
Here is my error page screen shot
