With the standard MVC capabilities, Laravel is a highly functional PHP framework that helps you build amazing web applications. In a very short time frame, it has become one of the most popular PHP frameworks. Laravel is specially designed for the development of web applications which are based on the Model View Controller model. Available for free, Laravel comes under an open-source license.
Laravel offers a large number of tools & features, and today it is supported by a great community of developers and experts. Comes with amazing features, it is similar to CodeIgniter or CakePHP.
Architecture of Laravel Applications
Known as a “full stack” framework; Laravel is capable of handling everything from HTML generation to database management. Its vertically-integrated web development environment provides a soothing experience for the developers. Developers can interact with Laravel with the help of command-line utility which generates and manages the project environment. It provides an outstanding command-line tool – Artisan which is used to create database schema stubs and skeleton code. Artisan handles configuration management and database schema migration.
Convention Over Configuration
Laravel consist some specific constraints on how you create your web applications. And the best part is that all these constraints make it simpler to build applications. Its strong preference for convention over configuration makes it different from other vertically integrated environments. On the other hand, some other frameworks such as Java, Python or PHP demands lots of XML configuration.
One Project Structure For All Laravel Projects
Most Laravel projects have the same directory structure in which each file places at its designated place ensuring that your project is semi-automatically organized by the Laravel itself.
Let’s have a look at the brief overview of how Laravel application works. Standard Laravel application structure consists an application directory which is divided into three subdirectories: 1. Models, 2. Views, 3. Controllers. Means, Laravel follows the model-view-controller (MVC) architectural pattern that creates a partition between “business logic” “presentation logic” related to a graphical user interface (GUI).
MVC Pattern Consists Three Components:
Models are based on real-world objects such as a person, products, and bank account. If you were creating a blog, your models should be post & comment. Models can be stored outside the app, usually in a database. A model drives all the business rules that implement on the data. Model acts as both a data store and a gatekeeper.
The visual representation of that model is called as View. It’s the result that the framework executes to the browser such as HTML represents the blog post. Based on a data in the model, view generates a user interface. For instance, an ecommerce website will display a list of products on a catalog screen.
The coordinator creates a link between the model and view. The controller is capable of processing input, acting upon the model, and choosing what action should be performed. Let’s again take the example of the blog; the controller will look for the latest comments for a blog post and pass them to the View for rendering.
While communicating with the Laravel, your browser transfers a request that is initiated by a web server and transferred to the Laravel routing engine. As Laravel router receives the request, it redirects to the relevant controller class method according to the routing URL pattern.
How to Install Laravel Framework
This amazing framework can be easily installed by following some simple steps.
As Laravel utilizes Composer for its dependencies, so you don’t need to download the ‘composer.phar’ archive. If you are using Windows, you can use Windows installer that is available for installation without any charges. As Laravel utilizes Composer for its dependencies, so you have to download the ‘composer.phar’ archive. After downloading, move this file to the directory ‘usr/local/bin’ or keep back in your project’s local directory.
There Are Different Methods Available For Installing This Framework:
Via Download: When the composer is installed, you need to get the latest version of Laravel framework’s and extract its entire content on your server. Now, execute the command “php composer.phar install” to install all the dependencies in your Laravel application’s root. Moreover, you need to install Git on your server for the successful completion of installation. Though, “php composer.phar update” needs to be executed to update the framework.
Via Laravel Installer: For this process, first you will need to download the PHAR archive and then move it to the directory ‘/usr/local/bin’. Once it is installed, you can use the ‘laravel new’ command in order to build a new installation in your desired directory.
Via Composer Create-Project: For this, you need to issue the command ‘create-project’ as “composer create-project laravel/laravel –prefer-dist” in the terminal.
So, it’s easy to install the framework easily by following these above-mentioned methods, where no configuration is required to start development. Followed by CodeIgniter, Symfony2, Phalcon, and others web frameworks; Laravel is a widely-preferred framework preferred by the most PHP developers today.
