In general, you can check simply using:

use Illuminate\Support\Collection;

....
if($variable instanceof Collection) { 
 ....
}

In fact, we are checking whether the $variableis a Collection-object or not.

Another example:

We know that Illuminate\Database\Eloquent\Collection extends from Illuminate\Support\Collection

Suppose:

$record = User::all();

Then:

dump($record instanceof \App\User); // returns false

While:

dump($record instanceof \Illuminate\Database\Eloquent\Collection); // returns true

This is what we usually do in a controller to validate a request:

$validated = $request->validate([
        'title' => 'required|unique:posts|max:255',
        'body' => 'required',
    ]);

Since the validate() method is not accessible in a Laravel middleware we should use facade for validating a request inside the middleware.

use Illuminate\Support\Facades\Validator;

and then :

$validator = Validator::make($request->all(), [
            'title' => 'required|unique:posts|max:255',
            'body' => 'required',
        ]);

To see all your routes compactly, you need to do:

php artisan route:list --compact

php artisan optimize will do the following tasks:

You have one .env file, but the contents can differ on each machine you run the application.

Do not forget to run the command php artisan config:clear after you have made the changes to the .env file. Do this php artisan env, which will return the correct version and assures you about what it is actually set!

The role of the .env file is to allow you to have different settings depending on which machine you are running your application. So on your production server, the .env file settings would be different from your local development environment.

production and local are just environment names that you can use to turn certain testing features on or off in different places. …

php artisan vendor:publish

Then just select the number you want:

For opening your current working directory in PhpStorm

You need first open Phpstrom and then go to Tools menu and find the
