How to get random array

Have you tried array_random()? In Laravel 5.5, its a helper.

In previous versions, you can use php function called array_rand().

array_random()

$name = ['value 1', 'value 2', 'value 3'];
return array_random($name);

array_rand()

$name = ['value 1', 'value 2', 'value 3'];
return $name[array_rand($name)];

if you re attempting to get random model / table data you could do something like this:

         $user = User::orderBy(\DB::raw('RAND()'))->first();

collect($name)->random()
