Question

How we can paginate through random records in laravel? for example:

Solution with Laravel + Eloquent

Before Eloquent query, set the session variable. I used time() for the session value, so I can keep the same ordering for a certain amount of time. For example, 3600 seconds (1 hour).

if ($request->session()->has('session_rand')) {

    if((time() - $request->session()->get('session_rand')) > 3600){
        $request->session()->put('session_rand', time());
    }
}else{
    $request->session()->put('session_rand', time());
}

Add ->orderBy() to the Eloquent query using DB::raw() and the session variable that we set above:

->orderBy(DB::raw('RAND('.$request->session()->get('session_rand').')'))
