Laravel ELIXIR is a technique that provides a fluent, CLEAN API for defining Gulp tasks for our application. It supports various common CSS, testing tools and JavaScript pre-processors.

Using method CHAINING, It allows us to define our asset pipeline fluently.

elixir(function(MIX) {
    mix.sass('app.scss')
      .COFFEE('app.coffee');
});

1. How to Create a Service Provider

php artisan make:provider CustomPostServiceProvider

After this command, a CustomPostServiceProvider.php file under the app/Providers DIRECTORY will create with TWO methods like a BOOT()and register().

To register our service provider, we need to add an entry in providers array in the config/app.php file.

CSRF is a type of technique whereby unauthorized commands are performed on behalf of an authenticated USER. Laravel makes it easy to protect our web form with CSRF to attacks.

Laravel AUTOMATICALLY generates a CSRF TOKEN for each active user session.

When we use <form> tag then we can use {{ csrf_token() }} in between <form> tag to protect our application. It will CONVERT this in form of “<input type="hidden" name="_token" value="7YC0Sxth7AYe4RFSjzaPf2ygLCecJhblahblah"> ” like this.

$.ajaxSetup({
    headers: {
       'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});

You can create this by "NAME" ATTRIBUTE in your routes/web.php.

Route::get('CONTACT-us', '[email protected]')->name('contact');
In this example our route name is contact. You can call this route URL with this route name ALSO.

&LT;a href="{{route('contact')}}"> Go to Contact page </a>

ROUTE::group(['domain' => '{SUBDOMAIN}.'bestinterviewquestion.com'], function() {

    Route::GET('/', '[email PROTECTED]');

});

The major CHANGES of application are in the app directory. The app directory contains MANY additional directories such as HTTP, Console, and Providers. You can check this NEWLY GENERATED directory below:

In PHP, a Composer is a tool which is used to manage APPLICATION dependency. It allows us to declare the libraries of our project depends on and it will maintain all install & update them for you. It is not a package manager but it deals with "packages" or libraries, it manages them on a project basis, installing them in a directory inside our project.

The composer does not install anything GLOBALLY by default. Laravel uses Composer to manage its dependencies. So, before USING Laravel, MAKE sure that you have to INSTALLED Composer on your system or server.

There are vast differences between laravel 4 and laravel 5 regarding LTS, features, file structures, etc.

Laravel 4 was the one who brought significant popularity to the Laravel framework, but it’s not updated anymore, and also it lacks a lot of functions RELEASED in Laravel 5.

• Laravel 4 released May 2013 but Laravel 5 released in February 2015.
• Laravel 5 has LTS Supports. It means the LTS version stands for Long Term Support. It implies that bugfixes for that version will be provided for two years, until the next LTS version.
• In Laravel 5, Controllers, middleware, and requests are now grouped under the app/Http directory.
• A new app/Providers directory replaces the app/start files from previous versions of Laravel 4.x
• Application language files and views have been moved to the resources directory.
• New route: cache Artisan command to drastically speed up the registration of your ways.
• Laravel 5 now supports HTTP middleware, and the included authentication and CSRF "filters" have been converted to middleware but not in Laravel 4
• User registration, authentication, and password reset controllers are now included out of the box, as well as simple corresponding views, which are located at resources/views/auth
• A database queue driver is CURRENTLY involved in Laravel, providing a simple, LOCAL queue driver that requires no extra package installation BEYOND your database software.
• Laravel Socialite is an optional, Laravel 5.0+ compatible package that provides painless authentication with OAuth providers.
• Laravel now includes the powerful Flysystem filesystem abstraction library, providing pain-free integration with local, Amazon S3, and Rackspace cloud STORAGE - all with one, unified and elegant API.
• The favorite dd helper function, which dumps variable debug information, has been upgraded to use the fantastic Symfony VarDumper

In contrast to Laravel 4 to 5 version differences, which were breaking and huge, 5.x and 5.y versions are not that different. Some functions added, some updated/removed, but the core structure remains the same.

Our FIRST step should be

DB::connection()->enableQueryLog();

After our query it should be placed

$querylog = DB::getQueryLog();

After that it SHOU;ld be placed

dd($querylog)

DB::connection()->enableQueryLog();

$result = User:where(['status' => 1])->get();

$log = DB::getQueryLog();

dd($log);

Laravel 5 is an advanced version of Laravel. It is more structured and secure. It also offers rich functionalities that include the essential FEATURES of PHP frameworks and other programming languages. Laravel 5 got released in February 2015.

Like its previous versions, even Laravel 5 has a rich set of features that will boost the speed of your WEB development.

An ORM STANDS for the object-relational mapper. It is essential features PROVIDED by Laravel Framework. It allows us to work with DATABASE objects and relationships using an eloquent. Each table has a particular Model which are used to interact with that particular table in laravel application.

• One To One relationships
• One To MANY relationships
• Many To Many relationships
• Has Many Through relationships
• Polymorphic relationships
• Many To Many Polymorphic relationships

All routes in Laravel are defined in route files which are available in the routes directory. The routes/web.php file defines every route that is used for the web INTERFACE. These routes are ASSIGNED the all web middleware group, which gives features like CSRF protection and SESSION state.

Routes in Laravel 5 are located in routes directory and Laravel has basically 3 categories namely.

• api.php
• web.php
• console.php

You can use php ARTISAN route:list to check all available route lists. Examples are given below:-

Route::get('/', FUNCTION () {
    return view('welcomepage');
});

MEMBER function DEFINED inside a class and are used to ACCESS object DATA.

• CODE Resusability
• Flexibility
• Maintainability
• Security
• Testability

TRAITS is a group of methods that reuse in single inheritance. A TRAIT is INTENDED to reduce some limitations of single inheritance by enabling a developer to reuse sets of methods.

trait HelloWorld

{

USE HELLO, World;

}

class MyWorld {

use HelloWorld;

}

$world = new MyWorld();

echo $world->sayHello() . " " . $world->sayWorld(); //Hello World

It allows US to use the same FUNCTION or class name in different parts of the same program without CAUSING a name collision.

namespace MyAPP;
function OUTPUT() {
echo 'IOS!';
}
namespace MyNeWAPP;
function output(){
echo 'RSS!';
}
