Google Map V3, how to get list of best driving route for multiple destinations?

Question

i would like to use Gmap API to calculate the best driving route for many destinations. I have read this page:

Answer 1

You might want to look at the Distance Matrix service: https://developers.google.com/maps/documentation/javascript/distancematrix

It gives you distances between a set of origins and destinations, and might help you with narrowing down options.

Answer 2

The link you refer to explains how to do this: admittedly you also get back some directions information you don't care about, but you can simply ignore it.

To be clear, you just make a directions request with some waypoints (say B,C and D) in addition to your origin and destination (A and E).

If using the web service, ensure you set optimize:true before listing your waypoints, and check the waypoint_order array (near the bottom of the result for this url) to get the info you want:

http://maps.googleapis.com/maps/api/directions/json?origin=Adelaide,SA&destination=Adelaide,SA&waypoints=optimize:true|Barossa+Valley,SA|Clare,SA|Connawarra,SA|McLaren+Vale,SA&sensor=false

If use the JS API, set optimizeWaypoints:true in your request.

As always, be sure you're abiding by the terms of service (e.g. results from your web service request must be displayed on a Google Map)

after hous of search i used this package https://github.com/alexpechkarev/google-maps with those parametres below :

$origin = ['lat' => 35.762288, 'lng' => -5.866525, 'ville' => 'tanger'];
    $destination = ['lat' => 33.565567, 'lng' => -7.552402, 'ville' => 'casablanca'];
    $points = [
        ['lat' => 33.951825, 'lng' => -6.839634, 'ville' => 'rabat'],
        ['lat' => 35.475028, 'lng' => -6.015167, 'ville' => 'assilah'],
        ['lat' => 35.178713, 'lng' => -6.132972, 'ville' => 'laarach'],
        ['lat' => 34.868921, 'lng' => -6.247939, 'ville' => 'moulay Bouslham'],
        ['lat' => 33.834129, 'lng' => -6.054144, 'ville' => 'khmissat'],
        ['lat' => 35.574788, 'lng' => -5.360490, 'ville' => 'Tetouan'],

    ];

    $wayPointsString = collect($points)->transform(function ($point) {
        return $point['lat'] . ',' . $point['lng'];
    })->implode('|');

    $data = \GoogleMaps::load('directions')
        ->setEndpoint('json')
        ->setParam([
            'origin' => collect($origin)->take(2)->implode(','),//tanger
            'destination' => collect($destination)->take(2)->implode(','), // casablanca
            'waypoints' => ['optimize:true|' . $wayPointsString
            ],
            'mode' => 'driving',
            'alternatives' => true,
            'departure_time' => 'now',
        ])
        ->get();

    $data = json_decode($data, true);
    $points_ = [];
    $points_[] = $origin;

    foreach ($data['routes'][0]['waypoint_order'] as $key => $value) {
        $points_[] = $points[$value];
    }
    $points_[] = $destination;
    dd($points_);

as a response :
