Answer 1

Have a look at the documentation.

You can use toJson(),to convert the collection to json object.

$users = DB::table('users')->get()->toJson();
dd($users);

You can also can do this in simple php way by using json_encode function

$users = json_encode($users);

Have a look at this link

Greetings and happy coding!

if we you laravel 5.5 then you should use eloquent-resources

Answer 3

Couple of things you can do, you can use default method ->toJson() with the user collection like this

$users = DB::table('users')->get();
$users->toJson();

If you do have troubles with it them you can php build in json_encode method here is the full documentation http://php.net/manual/en/function.json-encode.php

$users = DB::table('users')->get();
json_encode($users)

Hope this helps!

add "use Response;"

return Response::json([
    'data' => $value

Answer 5

in Laravel you can easily serialize your php object like so :

public static function getLocataireByCin($cin)
    {
        return Locataire::where('cin', $cin)
            ->first()
            ->toJson(JSON_PRETTY_PRINT);
    }

and then retrieve it on your frontEnd (using js/jquery for example ) :

$("#cinLocataire").keyup(function () {
        $.ajax({
            url: "{{ route('Caisse.store') }}",
            type: "POST",
            data: {
                cin: $(this).val()
            },
            success: function (locataireData) {
                var locataire = JSON.parse(locataireData); // <-- here
                console.log(
                    locataire.nom
                );
            },
        })
    });

If you are looking into doing if for a blade template you can use the @json Blade directive, like so:

<script type="text/javascript">
    var PARAMS = @json($params)
</script>

P.S.Tested in Laravel 5.6
