Welcome to Laravel Starter Guide. This tutorial series is designed to provide you all the information you need to get started with building web application using Laravel PHP framework. In this article you will learn What is Laravel? And why we need to use Laravel framework? and a brief introduction to Laravel version releases.
1. Introduction to Laravel PHP
Laravel is free, open-source and one of the more popular PHP web framework based on model–view–controller (MVC) architectural pattern. It is created by Taylor Otwell, intended to reduce the cost of initial development and improve quality of your code by defining industry standard design practices. Using Laravel, you can can save hours of development time and reduce thousand lines of code compared raw PHP.
Since its first release on June 2011, Laravel is has come a long way as the PHP language is evolving. The current Laravel framework version is 5.4.
2. Why use a framework at all?
PHP is one of the most popular programming languages, powered over 82% of websites around the world. The recent PHP 7 release made this server-side programming language better and more stable than ever. It is used by major players like Facebook, WordPress, Flicker, etc.
PHP is used by 82.7% of all the websites whose server-side programming language we know.
A framework is not necessary to develop application in PHP language. Than question is, why to use a framework at all? A few benefits of using a framework include:
- A framework makes development faster. You just need to focus on your development without having to worry about the some of the key fundamentals.
- Most of the PHP frameworks comes handy with a ORM (Object-relational mapping). That means you don’t have to write complex queries for performing CRUD (Create, Read, Update, and Delete) operations.
- Frameworks brings industry standard architectural patterns such as MVC to ensure rapid development and helps to write maintainable code
- Frameworks makes your application more scalable
- Frameworks are updated constantly with enhancements and patches to protect your site from security threats
- Framework helps to organise and manage resources better
- Frameworks with large user bases are likely more stable
The above benefits gives enough reasons to choose a framework rather than using raw PHP to create your web application. CodeIgniter, Symfony, Laravel, and Yii are some of the popular PHP frameworks available in market. In this tutorial series we have chosen Laravel as the framework of our choice. Rest of the tutorial we discuss only about Laravel.
3. What is Composer?
Composer(https://getcomposer.org/) is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.
Using composer, you can include third party read-to-use packages and libraries in your Laravel project and manage them all in one place using
composer.json file is a plane json file placed under the project root directory, which defines the metadata for all project package dependencies.
Laravel is packaged with out of the box dependency management Composer and Packagist. Using composer, you can include third party read-to-use packages and libraries in your Laravel project and manage them all in one place.
4. Laravel Features
Laravel PHP framework is powered with many out of the box features including view templating, built in authentication, routing, database access, file management, caching, etc. Let us review some of the major features supported by Laravel:
4.1. Database Access
Laravel also provides a cutting-edge suite of tools for interacting with databases. Database migrations enable you to easily design and modify a database in a platform-independent way. The migrations can then be run against any of the database types that Laravel supports (MySQL, PostgreSQL, MSSQL, and SQLite) and you won’t have any compatibility issues. Laravel’s Fluent Query Builder abstracts away the differences between different database types. Use it to build and execute robust queries.
Laravel’s ActiveRecord implementation is called Eloquent. Interacting with a database in an object-oriented way is the modern standard. With Eloquent, we can create, retrieve, update, and delete the database records without needing to write a single line of SQL. In addition to this, Eloquent provides powerful relationship management and it can even handle pagination automatically for you.
4.2. Command Line Tool
Laravel also ships with a command-line interface tool called Artisan. With Artisan, a developer can interact with their application to trigger actions such as running database migrations, executing unit tests, and schedule a job. Another beauty of Artisan is that, it is completely extensible so that you can add a new command to perform any type of functionality that you’d like.
Laravel allows you to organise all your website URLs through routers. If you want to change the link of some website or API, we need to change it at one file and your website should work as expected.
4.4. View Template Engine
The Blade templating engine cleans up your views by providing aesthetically pleasing replacements for inline PHP and by including powerful new features.
4.5. Job Scheduling
Introduced in Laravel 5.0, is an addition to the Artisan that allows programmatic scheduling of periodically executed tasks. Internally, Scheduler relies on the cron daemon to run a single Artisan job that, in turn, executes the configured tasks.
4.6. File System
Introduced in Laravel 5.0, is a file system abstraction layer that allows local file systems and cloud-based storage services provided by Amazon S3 and Rackspace Cloud to be used transparently and in the same way.
4.7. Subscription & Billing
If you want to develope a website like Newspaper subscription/billing website, Laravel is a perfect solution. Since, Laravel 4.2 it introduced, Cashier, that provides an interface for managing subscription billing services provided by Stripe, such as handling coupons and generating invoices, etc.
4.7. Authentication & Socialite
Laravel is bundled with basic authentication. Basic authentication can be configured to web pages and API easily with few steps. Since version 5.0, laravel includes as an optional package, provides simplified mechanisms for authentication with different OAuth providers, including Facebook, Twitter, Google, GitHub and Bitbucket.
5. Laravel Version History
Laravel PHP framework is evolved with series of frequent updates since its initial beta release on June 2011. Each version powered with new advanced features that makes Laravel stand out as a strongest contender to its rival frameworks CodeIgniter, Symfony, Laravel, and Yii.
