Quickbook PHP SDK与yii1.1.14集成错误

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

enter image description here

I solved the above issue by modifying the code as below and make it compatible to run with yii1.X

Modify in the below path in sdk library XSD2PHP/src/com/mikebevz/xsd2php/Bind.php

(!class_exists(class_name)($className))

to

!(class_exists(class_name)($className,false))
