Seeders tutorial in Laravel 11

 <?php

            student::create([

                "name" => fake()->name(),

                "email" => fake()->unique()->email()

            ]);

        }

        // $json = File::get(path: "database/json/students.json");

        // // To use sub methods of collect(), we have used collect() as shown below :

        // $students = collect(json_decode($json)); //json_decode() converts json to Array

        // // When we create table and if we insert data in table using "create()" method at that time

        // // we must have to use "timestamps()" column while creating table because "create()" method

        // // needs to add two column values "created_at" and "updated_at" in table that's why we must

        // // use "timestamps()" column but if we use old method "insert()" instead of "create()" then

        // // there is no need to use "timestamps()" method

        // $students->each(function ($stu) {

        //     student::create([

        //         "name" => $stu->name,

        //         "email" => $stu->email
