What is Laravel?

Laravel is an open source MVC PHP Framework under MIT License

MVC Architecture Model : Model deals with backend logical

structure of the application such as data base records. In laravel it is denoted as Eloquent model.

View : View deals with frontend such as the HTML, CSS. In laravel it works with Blade Template Engine and denoted as View.

Controller : Model and View can be communicated through Controllers. In laravel it is denoted as Controller.

Installing LaravelRequirements:The Laravel framework has a few system

requirements. PHP version should be 5.5.9 or greater Apache or any other compatible web server Datatabase like MySQL Composer dependency manager IDE Tool Such as PHP Storm or Any Editor like

Sublim Text, Notepad++.

Installing Laravel In Linux Apache, MySQL & PHP can be

installed through terminal $ apt-get install php5-common libapache2-

mod-php5 php5-cli php5-mysql php5-curl

Installing Laravel To Check PHPuse php -v at terminal to check PHP version

Or else use localhost to check php information

Installing Laravel

Installing Laravel Laravel utilizes Composer to manage its

dependencies. To install composer through terminal

$ curl -sS https://getcomposer.org/installer | php

$ mv composer.phar /usr/local/bin/composer$ composer global require

"laravel/installer=~1.1"

Laravel directory structure After crating laravel first app you will notice

there is huge laravel directory structure

Laravel directory structure Let us discuss the directory structure in brief It comes as no surprise that all Laravel projects have

essentially the same directory structure - one in which every file has its designated place. By gently forcing this directory structure upon developers, Laravel ensures that your work is semi-automatically organized the “Laravel way”.

As you can see, this standard directory structure consists of quite a few subdirectories. This wealth of subdirectories can be overwhelming at first, but we’ll explore them one by one. Most of your work will happen in the app/ folder, but here’s a basic rundown on the function of each of the files and folders:

Laravel directory structure Top-level Folders and their purpose /app/ Contains the controllers, models, views and assets for your

application. This is where the majority of the code for your application will live. You will be spending most of your time in this folder!

/public/ The only folder seen to the world as-is. This is the directory that you have to point your web server to. It contains the bootstrap file index.php which jump-starts the Laravel framework core. The public directory can also be used to hold any publicly accessible static assets such as CSS, Javascript files, images and other files.

/vendor/ A place for all third-party code. In a typical Laravel application, this includes the Laravel source code and its dependencies, and plugins containing additional prepackaged functionality.

Laravel directory structure /app/Http/routes.php Suppose routes.php file contains the below mentioned

code Route::get('/', function(){

return view('welcome');}); When you browse http://localhost/project-name/public/ It goes to routes.php and finds get request and as a result

it goes to return view('welcome'). So it then moves to view directory.

Laravel directory structure /resources/views/welcome.blade.php Blade is the simple, yet powerful

templating engine provided with Laravel.

The complete user viewable contents can be placed here

It uses html, css,javascript and php

Laravel directory structure Suppose routes.php has the below code Route::resource('photo', 'PhotoController'); It goes to App/Http/Controllers/ directory

and finds PhotoController.php which contains logic for backend data.

This single route declaration creates multiple routes to handle a variety of RESTful actions on the photo resource.

Laravel directory structure Methods or Actions Handled By Resource Controller VerbPath Action Route Name GET /photo index photo.index GET /photo/create create photo.create POST /photo store photo.store GET /photo/{photo} show photo.show GET /photo/{photo}/edit edit photo.edit PUT/PATCH /photo/{photo} update photo.update DELETE /photo/{photo} destroy

photo.destroy

Laravel directory structure PhotoController.php class PhotoController extends Controller{ public function index() { return view('welcome'); }

public function create(){ //logic for create photo }public function store(){ //logic for store photo }public function show(){ //logic for show photo}public function edit(){ //logic for edit photo }public function update(){ //logic for update photo }public function destroy(){ //logic for destroy photo }
