PHP / Laravel - 结合结果（模型关系）

Question

Right now I have below data:

Now the problem with above is, that it's creating a new array for each entry in my database.

I would very much like to get below output:

The difference is here that:

• All the routes that are the same, should be grouped. So if the Route is the same, it should be under the same route list.

• If the Carrier under the route is the same, then it should be under that route and carrier

• If the route is different, it should start a new list (**Route: XYZ to XYZ)

Current Code:

Controller.php:

public function show()
    {
        $routes = Routes::where('id', '>=', 1)
        ->with('routeStops', 'getVessel')
        ->get()
        ->toArray();

        foreach ($routes as $key => $value) {
            echo '<h2>Route: ' . $value['origin'] . ' to ' . $value['destination'] . '</h2>';
            $carrier = Carriers::where('id', $value['get_vessel']['carriers_id'])->first()->name;
            echo 'Carrier: ' . $carrier . '';
            dump($value);
        }

    }

This is my models:

Routes.php

/**
 * Get the route stop associated with this route.
 */
public function routeStops()
{
    return $this->hasMany('App\RouteStops', 'route_id');
}

/**
* Get the vessel record associated with this route.
*/
public function getVessel()
{
    return $this->belongsTo('App\Vessels', 'vessel_id');
}

How can I do so I achieve the 2nd desired output?
