retrieve Google user details with OAuth -

i implementing google login api first time. works fine able retrieve email addresses only. have tried other ways no success. how can other user details username?

include('/../src/google/autoload.php');              /*         * **********************************************            attention: fill in these values! make sure            redirect uri page, e.g:            http://localhost:8080/user-example.php           * ********************************************** */            $client_id = 'bla-bla-bla';          $client_secret = 'bla-bla-bla';          $redirect_uri = 'bla-bla-bla/google_login';              /*         * **********************************************            make api request on behalf of user. in            case need have valid oauth 2.0            token user, need send them            through login flow. need            information our api console project.           * ********************************************** */            if (isset($_get['code'])) {              $client = new google_client();              $client->setclientid($client_id);              $client->setclientsecret($client_secret);              $client->setredirecturi($redirect_uri);                $client->setscopes(array('https://www.googleapis.com/auth/userinfo.email', 'https://www.googleapis.com/auth/userinfo.profile'));                $client->authenticate($_get['code']);                           $redirect = 'http://' . $_server['http_host'] . $_server['php_self'];              $google_oauth = new google_service_oauth2($client);              print_r($google_ouath);//give error undefined variable: google_ouath              print_r($google_ouath->userinfo); //give error undefined variable: google_ouath              print_r($google_ouath->userinfo>get());//give error undefined variable: google_ouath              $google_account_email = $google_oauth->userinfo->get()->email; //works fine              //$google_account_getdisplayname = $google_ouath->userinfo->get()->displayname;              //$google_account_givenname = $google_ouath->userinfo->get()->givenname;              //$google_account_name = $google_ouath->userinfo->get()->name;              echo '<pre>';                print_r($google_account_email);                echo '</pre>';              exit;

that's because of spelling error in variable names here:

print_r($google_ouath);//give error undefined variable: google_ouath print_r($google_ouath->userinfo); //give error undefined variable: google_ouath print_r($google_ouath->userinfo>get());//give error undefined variable: google_ouath 

variable name google_ouath should google_oauth i.e. a , u should switched, becomes:

print_r($google_oauth); print_r($google_oauth->userinfo); print_r($google_oauth->userinfo>get()); 

you should rid of deprecated long scope names:

$client->setscopes(array('https://www.googleapis.com/auth/userinfo.email', 'https://www.googleapis.com/auth/userinfo.profile')); 

and use short-hand , openid connect compliant form:

$client->setscopes(array('email', 'profile'));
