Google Places API Data to Custom Fields

Hi Long,
I am trying to get not only location data but also place details. I have fixed my code like below, but I really appreciate it if you can help me to save this data to a custom table which I have already created with metabox custom table extension.

<?php

add_action( 'save_post', 'google_places_data', 10, 4 );

function google_places_data( $post = null ) {
    global $post;
    if($post->post_type == 'hamburg'){
        
    if ( ! $post = get_post( $post ) )
        return;
    if ( ! $place_id = get_post_meta( $post->ID, 'place_id', true ) )
        return; // No place ID configured for this post

    if ( $data = get_post_meta( $post->ID, 'place_data', true ) ) {
        if ( $data->timeout <= current_time( 'timestamp' ) )
            $data = null; // Void the cache if it's old
    }

    if ( ! $data ) {
        $args = http_build_query(
            array(
                'key' => 'MY API KEY', // API key
                'place_id' => $place_id
                )
            );

        $http = wp_remote_get( "https://maps.googleapis.com/maps/api/place/details/json?$args" );
        if ( $body = wp_remote_retrieve_body( $http ) ) {
            if ( $data =@ json_decode( $body ) )
                $data->timeout = current_time( 'timestamp' ); // Cache data for 1 hour
                
            $address_components_length = count($data->result->address_components);
            
            $bezirk; $city; $state; $post_code;
            foreach ($data->result->address_components as $component_data){
                $type = $component_data->types[0];
                if ($type == 'sublocality_level_1') {
                    $bezirk = $component_data->long_name;
                } else if ($type == 'locality') {
                    $city = $component_data->long_name;
                } else if ($type == 'administrative_area_level_1') {
                    $state = $component_data->long_name;
                } else if ($type == 'postal_code') {
                    $post_code = $component_data->long_name;
                }
                
            }
            

            $name = $data->result->name;
            $formatted_address = $data->result->formatted_address;
            $formatted_phone_number = $data->result->formatted_phone_number;
            $rating = $data->result->rating;
            $total_rating = $data->result->user_ratings_total;
            $google_maps_url = $data->result->url;
            $website = $data->result->website;
            
            update_post_meta( $post->ID, 'name', $name );
            update_post_meta( $post->ID, 'formatted_address', $formatted_address );
            update_post_meta( $post->ID, 'formatted_phone_number', $formatted_phone_number );
            update_post_meta( $post->ID, 'bezirk', $bezirk );
            update_post_meta( $post->ID, 'city', $city );
            update_post_meta( $post->ID, 'state', $state );
            update_post_meta( $post->ID, 'post_code', $post_code );
            update_post_meta( $post->ID, 'rating', $rating );
            update_post_meta( $post->ID, 'total_rating', $total_rating );
            update_post_meta( $post->ID, 'google_maps_url', $google_maps_url );
            update_post_meta( $post->ID, 'website', $website );

        }

        if ( $data ) {
            update_post_meta( $post->ID, 'place_data', $data );
            
        } else {
            echo 'api error';
        }

    }
    return $data;
    }
}
