You can check for 3 variables in the google response (json) to find the current cityname. Hence there is 3 different interpretation of the name:
Country | AdministrativeArea | |_AdministrativeAreaName (cityname) | |_Locality_LocalityName (cityname) | |_SubAdministrativeArea | |_Locality_LocalityName (cityname) if ($this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->Locality->LocalityName != NULL) { $code['cityname'] = $this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->Locality->LocalityName; } elseif ($this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->SubAdministrativeArea->Locality->LocalityName != NULL) { $code['cityname'] = $this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->SubAdministrativeArea->Locality->LocalityName; }If you have more then a Placemark you need to loop through all the array.
