php - Eloquent and Query Builder -

is laravel eloquent's save() method doing query builder's job?

query builder:

db::table('flights')     ->where('id', 1)     ->update(['name' => 'new flight name']); 

eloquent:

$flight = app\flight::find(1); $flight->name = 'new flight name'; $flight->save(); 

if that's true, same eloquent's create()? watching laravel's official video tutorials, , see author uses eloquent's create() , save() inside controller. difference between query builder , eloquent? can use eloquent inside controller?

• yes, query builder , eloquent methods doing same job, however if use eloquent model in general able use eloquent relationship speed development process , make life easier. fact if deal huge data in database query builder faster.

• the difference between save , create save accepts full eloquent model instance while create accepts plain php array red docs.
