if ($response->status == 'OK') {
    $latitude = $response->results[0]->geometry->location->lat;
    $longitude = $response->results[0]->geometry->location->lng;

试试这个

 <?php
    $address = "Ahmedabad, India";
    $formattedAddr = str_replace(' ','+',$address);
            //Send request and receive json data by address
            $geocodeFromAddr = file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address='.$formattedAddr.'&sensor=false&key=key');
            $output = json_decode($geocodeFromAddr);
            print_r($output);
            //Get latitude and longitute from json data
            $data['latitude']  = $output->results[0]->geometry->location->lat;
            $data['longitude'] = $output->results[0]->geometry->location->lng;
            //Return latitude and longitude of the given address
            if(!empty($data)){
                return $data;
            }else{
                return false;
            }

    ?>
