发送逗号分隔在 php 和 laravel 的循环中生成的一些数组

Question

suppose we have an Object that accept some value as array that is separated by comma:

$keyboard = new Keyboard(
            ['value1'],
            ['value2'],
            ['value3'],
            ['value4']
        );

Now I want to fetch some value from database via a loop and send them finally to that object. but I do not know how can I collect them and send a comma separated list of them.

I write this code But can not get appropriate result from it:

$brands = Option::with('translations')->whereHas('attribute', function ($query) {
                    $query->where('type', '=', 'brand');
                })->get();

                $titles = [];
                foreach ($brands as $key => $brand) {
                    $titles [] = array($brand->title_fa);
                }

                $keyboard = new Keyboard(
                    $titles
                );

Answer 1

You can use ... operator to pass parameters. But check before whether size of an array is proper.

$keyboard = new Keyboard(...$titles);

Answer 2

First I suggest plucking the value that you want and then map them

Look at the Laravel Collection methods to avoid doing unnecessary loops and doing it more fluent

https://laravel.com/docs/7.x/collections

$brands = Option::with('translations')->whereHas('attribute', function ($query) {
                    $query->where('type', '=', 'brand');
                })->get()
                  ->pluck('title_fa')
                  ->map(function($brand){ return [$brand]; })->all()

Now you have a $brands array as required

So you can pass it as an array or as a Varidic params using the Splat operator as suggested in the other answer

$keyboard = new Keyboard($brands);
$keyboard = new Keyboard(...$brands);
