Laravel is an open-source PHP web framework. It created by Taylor Otwell in 2011 (first Laravel v1) and intended for the development of web applications following the Model View Controller (MVC) architectural pattern. Laravel is a web application framework with expressive, elegant syntax. We believe development must be an enjoyable, creative experience to be truly fulfilling. Laravel attempts to take the pain out of development by easing common tasks used in the majority of web projects, such as authentication, routing, sessions, and caching.
Laravel aims to make the development process a pleasing one for the developer without sacrificing application functionality. Happy developers make the best code. To this end, we've attempted to combine the very best of what we have seen in other web frameworks, including frameworks implemented in other languages, such as Ruby on Rails, ASP.NET MVC, and Sinatra. Laravel is accessible, yet powerful, providing powerful tools needed for large, robust applications. A superb inversion of control container, expressive migration system, and tightly integrated unit testing support give you the tools you need to build any application with which you are tasked.
As of March 2015, Laravel is regarded as one of the most popular PHP frameworks, together with Symfony, Zend, CodeIgniter, Yii2 and others. Laravel 5.4, released in January 24, 2017. This release has many new features, like Laravel Dusk, Laravel Mix, Blade Components and Slots, Markdown Emails, Automatic Facades, Route Improvements, Higher Order Messaging for Collections, and many others. Laravel v5.5, released in August 30, 2017.Next Laravel v5.6 in 2018.
What is Laravel?
Laravel is free, open-source framework and one of the more popular PHP web framework based on Model View Controller (MVC) architectural pattern. It was created by Taylor Otwell. Laravel was created to provide a more advanced alternative to the CodeIgniter framework, which does not provide features like built-in user authentication and authorization modules.

Why Laravel?
Laravel is one of most popular framework and it is open-source latest web application framework that used for designing customized web applications easily and quickly.

What are the features of Laravel framework?
Some Features of Laravel framework:
Template engine: Laravel Frame is highly recognized for its built-in lightweight templates that help you create stunning designs by seeding dynamic content. In addition to this, it has multiple widgets that incorporate CSS and JS code with solid structures. The Laravel framework templates are innovatively designed to create a simple design with distinctive sections.
Bundles: These are small packages which you may download to add certain functionality to your web application. Hence, saving a lot of coding stuff and time. These may be containing some custom functionality.
Unit testing: It is an important part of Laravel framework. It runs hundreds of tests to ensure that new changes don't unexpectedly break anything. Laravel is widely considered to have some of the most stable releases in the industry as it is cautious of the known failures. Slowly it is being liked by the developers. It also makes it easy to write unit-tests for own code. One can then run tests with the "Artisan" command-line utility.
Eloquent ORM (Object-Relational Mapping): Laravel framework offers the Eloquent ORM that includes a simple PHP Active Record implementation. It lets the web app developers issue database queries with PHP syntax rather than writing SQL code. Every table in the database possesses a corresponding Model through which the developer interacts with said table. An ORM is relatively faster than all other PHP frameworks.
Routing system: In this framework takes an incredibly simple and easy-to-use approach to routing. Most beginner PHP developers aren’t familiar with anything other than the most natural of route systems. It brings more flexibility and control over which route is triggered on the application. A directory is created to match any desired URI.
Restful Controllers: Rest controllers are an optional way to separate your GET and POST request logic. In a login example your controller's get_login () action would serve up the form and your controller's post_login() action would accept the posted form, validate, and either redirect to the login form with an error message or redirect your user to their dashboard.
Libraries & Modular: Laravel is also popular due to its Object Oriented libraries as well as many other pre-installed libraries. These pre-installed libraries are not found in any other PHP frameworks. One of the preinstalled libraries is an Authentication library which is easy-to-implement and has many latest features, such as checking active users, Bcrypt hashing, password reset, CSRF (Cross-site Request Forgery) protection, and encryption. Furthermore, this framework is divided into individual modules that adopt modern PHP principles allowing developers to build responsive, modular, and handy web apps.
Security: Application security is one of the most important concerns in web application development. At the time of developing an application, each programmer has to use some effective ways to make it secure. Laravel handles the security of web applications within its own framework. It uses the hashed and salted password meaning that the password would never save as plain text in a database. It also uses "Bcrypt Hashing Algorithm" for generating an encrypted representation of a password. In addition, this PHP web development framework uses prepared SQL statements which makes injection attacks unimaginable.

What is Lumen?
Lumen is micro-framework by Laravel. It is developed by creator of Laravel Taylor Otwell for creating smart and blazing fast API’s.Lumen is built on top components of Laravel. As Lumen is a micro-framework not a complete web framework like Laravel and used for creating API’s only, so most of components as HTTP sessions, cookies, and templating are excluded from Lumen and only features like routing, logging, caching, queues, validation, error handling, database abstraction, controllers, middleware, dependency injection, Blade templating, command scheduler, the service container and the Eloquent ORM are kept.

What is Eloquent ORM in Laravel?
Object-relational Mapping (ORM) is a programming technique for converting data between incompatible type systems in object-oriented programming languages. Laravel's eloquent object-relational mapper (ORM) is one of the most-loved features of the framework. The Eloquent ORM included with Laravel provides a beautiful, simple Active Record implementation for working with your database. Each database table has a corresponding "Model" which is used to interact with that table.

What is Compiling Assets (Laravel Elixir)?
Laravel Elixir provides a clean, fluent API for defining basic Gulp tasks for your Laravel application. Elixir supports common CSS and JavaScript pre-processors like Sass and Web pack. Using method chaining, Elixir allows you to fluently define your asset pipeline. For example:
elixir(function(mix) {

What are Facades in Laravel?
Facades provide a "static" interface to classes that are available in the application's service container. Laravel "facades" serve as "static proxies" to underlying classes in the service container, providing the benefit of a terse, expressive syntax while maintaining more testability and flexibility than traditional static methods.
All of Laravel's facades are defined in the Illuminate\Support\Facades namespace. So, we can easily access a facade like so
use Illuminate\Support\Facades\Cache;
Route::get('/cache', function () {
    return Cache::get('key');

How to use custom table in Laravel Modal?
We can use custom table in laravel by overriding protected $table property of Eloquent. Below is sample uses
class User extends Eloquent{
 protected $table="my_user_table";

What are Laravel's Contracts?
Laravel's Contracts are a set of interfaces that define the core services provided by the framework. For example, an Illuminate\Contracts\Queue\Queue contract defines the methods needed for queueing jobs, while the Illuminate\Contracts\Mail\Mailer contract defines the methods needed for sending e-mail. Each contract has a corresponding implementation provided by the framework. For example, Laravel provides a queue implementation with a variety of drivers, and a mailer implementation that is powered by Swift Mailer.

What are Bundles, Reverse Routing and The IoC container?
Bundles: A bundle can have its own views, configuration, routes, migrations, tasks, and more. A bundle could be everything from a database ORM to a robust authentication system. These are small functionality which you may download to add to your web application.
Reverse Routing:  Its reverse-routing is generating URLs based on route declarations. This allows you to change your routes and application will update all of the relevant links as per this link.
IOC container: The Laravel inversion of control container is a powerful tool for managing class dependencies. Dependency injection is a method of removing hard-coded class dependencies. It gives you Control gives you a method for generating new objects and optionally instantiating and referencing singletons.

What is Service container?
The Laravel service container is a powerful tool for managing class dependencies and performing dependency injection. Dependency injection is a fancy phrase that essentially means this: class dependencies are "injected" into the class via the constructor or, in some cases, "setter" methods.
