step1 create a controller usning following comand php artisan make:controller StudentController use the code mentioned below in controller :- <?php namespace App\Http\Controllers; use Illuminate\Http\Request;Use App\User; class StudentController extends Controller{      public function index()    {         $students = User::all();       return view(‘home’,compact(‘students’));   }} Step 2 Using foreach loop just display the data in tabular forn by creating a table in home page using mentioned below code in home.blade.php Step 3 The last and and final step is to set route to call studentController to view data. Just add following code in route/web.php Route::get(‘view-records’,’StudentController@index’)->name(‘view-records’); complted :

The process of deriving or making a new class from old class is known as inheritance . syntax for decleration of child or new class :- class childClassName extends ParentClassName{            statement ;    } The code is being re-used from one class to another. We need not required to re-write the same thing again and again. Extensibility is one of the advantages of the inheritance in which we can extend the base class feature without making little or no changes to fulfill the business requirements. we

Functions are used to make the programming very easy .The code is written once in the function and whenever the code is required, the function is called by its name instead of writing the whole code again. This is the benift of using function. in other word we can say, A Function is a reusable piece or block of code that performs a particular action.

Modes Description r Read only. Starts at the beginning of the file r+ Read/Write. Starts at the beginning of the file w Write only. Opens and clears the contents of file; or creates a new file if it doesn’t exist

When you write code, you want the same block of code to run over and over again in a row. Instead of adding several almost equal code-lines in a script, we can use loops to perform this type of task .  We have the following looping statements in php :- while:- The while loop will print the loop index.  Then, the index will be checked with the while condition to process the code within the loop block. The loop will print
