What is PHP Laravel 7 and How to install PHP Laravel 7 in Ubuntu 20.10?
What is the need for using a framework? A framework is a platform which is used to simplify the process of creating web applications. It is something which provides you a structure around which you could add code to have a great fuctionality of the system.It allows a standard way of creating applications. While we creating web application,without framework, first you may have to create a empty folder, then create index.html or index.php files,autoload files, session files etc.And you have to do this task repeatedly for each project your are creating.Frameworks reduces this type of redudancy in doing tasks and helps us to focus on logic of the web applications we are creating and it also saves our precious time. Frameworks follows a MVC (Model View Controller)pattern. It controls the flow of data from Model, View to Controller and we have to just worry only about logic not fuctionality of web applications. Model: It will focus on the what type of data the web applications dealing with. View:It provides an user interface for developing applications.Views in framework is like a small adapter that resides on the top of the DOM. Controller:It is a handler of inputs,such as clicks or browser events. If we use a framework for development of web applications , then framework designer will always time to time update that framework, and we not have to worry about new evolving technologies or patterns. Why choose Laravel and what are its features? Php language has various frameworks Laravel, Symfony, CodeIgniter, Yii 2, Phalcon, CakePHP, Zend , Slim, etc.Laravel is one of the most popular framework.It is an open source PHP framework and is developed by Taylor Otwell. User Authentication: Most of the modern day web applications need user authentication and it can be done in super easy by using Laravel Framework for that you just need some minimum configurations. Laravel creates components like user model, the register and login controller and corresponding view as well.It helps to add functionality as per the desired business logic of application. Socialite packages offered by Laravel enables your application to authenticate users using various social networks like Facebook, Google Plus and Twitter. Composer For Dependency Management: Composer helps you to install laravel packages and also check package.json files to see what dependencies the application is using.A Composer also helps to update dependencies using a single Composer command. Blade Templating Engine: Blad makes view code clean and also offers the template inheritance so that you could divide your templates into sections and inherit those sections into other view files. The Eloquent ORM: Eloquent is laravel ORM (Object Relationship Mapping) which helps to fetch data from database,creates relationships between tables ,create various joins in tables and also offers many helper function that make interacting with the database super easy.Some commonly using databases are MySQL,PostgreSQL,SQLite,SQL Server and using Eloquent provides compatability with any of these databases. Ques And Scheduler: While developing an application, there are many time consuming tasks like generation of a PDF report as CSV file that the user has requested.We must ensure that such type of tasks do not create a bottleneck in the user's process. Ques services of Laravel provides a unified API to defer such tasks for a later stage in the application. Command Scheduler: Laravel’s Command Scheduler provides a clean API schedule various tasks using the inbuilt functions. So there is no need to log in to your machine’s terminal using SSH, and all these scheduled jobs are a part of your code. Clean And Simple Routing: Laravel could handle all web routes using web.php file. Laravel could group easily the routes required for common middleware. Convention Over Configurations Approach: Different components have different naming conventions and hardly have to focus on the configurations.Zend like frameworks are highly depend on configurations but Laravel framework will take care these naming conventions and everything will start to work magically. Easy Notification Emails: Every modern-day applicatios has email notification facility.Laravel helps in sending out email notification and is super easy.Laravel facilitates sending mail through local or cloud based services through various notification email services such as Mailgun, adrill, SparkPost, Amazon SES, Send Mail etc.And can also send notifications via Slack and SMS using Nexmo. Artisan Commands: Artisan is the command line interface for Laravel and helps developers to automate many task using the command line itself.Artisan commands can be used for doing comman tasks such as, creating a model, creating a controller, creating a database seeder, migrating the database, so on and so forth. Testing Automation For Test Driven Development: Using Laravel,its became easy to write uit tests for your application and ensure that things are working the way you want them to.It supports PHPUnit and makes test-driven development for PHP applications very easy. Separation Of Business Logic And Presentation Code:Laravel follows a Model View Controller (MVC) architectural pattern to separate the business logic from the view. Laravel Installation Let's discuss about installation of Laravel in Linux OS. Before Installing Laravel, we must checks the requirements that to be satisfied by server. These are that requirements: PHP >= 7.2.5BCMath PHP Extension Ctype PHP Extension Fileinfo PHP extension JSON PHP Extension Mbstring PHP Extension OpenSSL PHP Extension PDO PHP Extension Tokenizer PHP Extension XML PHP Extension Fortunately, Installing LAMP before Laravel will make server satisfies all these requirements.

We’ll download it, verify that it’s not corrupted, and then use it to install Composer. Curl should be present in your system, type curl -sS https://getcomposer.org/installer -o composer-setup.php if this error occurs, ie is curl not found,then install curl first shinimol@shinimol-Lenovo-G50-80:~$ curl -sS https://getcomposer.org/installer -o composer-setup.php Command 'curl' not found, but can be installed with: sudo apt install curl To install curl, type $ sudo apt install curl shinimol@shinimol-Lenovo-G50-80:~$ sudo apt install curl Curl installed successfully. So now we are going to install Composer.Composer is used to facilitate installation and updates for project dependencies. It will check which other packages a specific project depends on and install them for you, using the appropriate versions according to the project requirements. Composer is also commonly used to bootstrap new projects based on popular PHP frameworks, such as Symfony and Laravel.
