If you would like to get address from latitude and longitude. You can use below function:

public function getAddressbylatlong($latitude, $longitude){


        $latlng = $latitude. ','.$longitude;
        $geocode = file_get_contents('http://maps.google.com/maps/api/geocode/json?latlng='.$latlng.'&sensor=true');

        $geocodedinfo = json_decode($geocode);

        foreach ($geocodedinfo->results[0]->address_components as $component) {
            $convertedComponent = (array) $component;
            #country

            if (in_array('country', $convertedComponent['types'])) {
                $this->country = $convertedComponent['long_name'];
            }
            #postcode
            if (in_array('postal_code', $convertedComponent['types'])) {
                $this->postcode = $convertedComponent['long_name'];
            }
            #city
            if (in_array('administrative_area_level_2', $convertedComponent['types'])) {
                $this->city = $convertedComponent['long_name'];
            }
            #state
            if (in_array('administrative_area_level_1', $convertedComponent['types'])) {
                $this->state = $convertedComponent['long_name'];
            }
            #district
            if (in_array('administrative_area_level_2', $convertedComponent['types'])) {
                $this->district = $convertedComponent['long_name'];
            }
            #st_addr1
            if (in_array('locality', $convertedComponent['types'])) {
                $this->st_addr1 = $convertedComponent['long_name'];
            }
            #st_addr2
            if (in_array('route', $convertedComponent['types'])) {
                $this->st_addr2 = $convertedComponent['long_name'];
            }
        }

        $address = $this->st_addr1.' '.$this->st_addr2.' '.$this->city.' '.$this->state.' '.$this->postcode.' '.$this->country;
        return $address; 
    }
