Laravel update and massupdate data

laravel uses the update method to update a single or multiple row data. First, we get a model row by where condition then applies update method. In the update method, we pass an array of columns with values.

update() method used to update all data that are marching in where condition so it also called mass assignment. When we use the update method then also give some configuration in the model like protected $guarded = [];.

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Student;

class StudentController extends Controller{
 public function index(){
    $student = Student::where('salary', '>' ,'10000')->update(['position', 'senior']);
  }
