Laravel tips: Model::findMany is useful

When you want to get multiple results of find with array of ID, you can pass the array to Model::find.

This feature started to be documented since Larave 5.2, but I found that we can use it even in Laravel 5.1.
I read Laravel source code (with no objective) then found it.

>>> App\User::find([1,2,3]) => Illuminate\Database\Eloquent\Collection {#1090 all: [ App\User { id: 1 }, App\User { id: 2 }, App\User { id: 3 }, ], } 

I used to write like User::whereIn([1, 2, 3])->get() before I found this technic.

We can also use findMany method. Actually find method runs findMany if the first argument is array.

in laravel/framework/src/Illuminate/Database/Eloquent/Builder.php

public function find($id, $columns = ['*']) { if (is_array($id) || $id instanceof Arrayable) { return $this->findMany($id, $columns); } return $this->whereKey($id)->first($columns); } public function findMany($ids, $columns = ['*']) { if (empty($ids)) { return $this->model->newCollection(); } $this->query->whereIn($this->model->getQualifiedKeyName(), $ids); return $this->get($columns); }

So we can use this method like User::findMany([1, 2, 3]).
I personally prefer this way because it is more explicit.
