Introduction
Hello Ninjas! Welcome to our article on PHP and web programming. Web development is a very famous domain in computer science. It involves designing, developing, maintaining, and testing web applications. You require a tool and scripting language for developing web applications. PHP is one such scripting language.
This article will discuss Laravel Composer in PHP. We will discuss the installation process for Laravel Composer.
PHP is an open-source general-purpose scripting language designed for web development. It was released in 1995 by Rasmus Lerdorf. It is an acronym for "PHP: Hypertext Preprocessor". It is easier to learn and user-friendly scripting language.
It handles dynamic content, session monitoring, databases, and creating complete websites. It supports multiple databases, including MySQL, Oracle, PostgreSQL, and Microsoft SQL Server. The ability to be used on various platforms increases the use of PHP by web developers.
Laravel is an open-source PHP framework for developing web applications. It was developed by Taylor Otwell and released in 2011. It follows the MVC(model view controller) architectural pattern. It makes the development of web applications easier and more convenient.
Laravel makes use of pre-existing parts from other frameworks to build online applications. Hence the resulting web application is more organized and practical.
A composer is a tool that integrates all the libraries and dependencies in your Laravel-developed web applications. You can install various third-party libraries effortlessly using Composer to help build applications faster.

XAMPP (Windows, MySQL, Apache Server, Perl, and PHP) and LAMP (Linux, MySQL, Apache Server, Perl, and PHP) are the most popular. We will use XAMPP in this article.

Step 2. Run the command composer global require laravel/installer. The laravel installer will be installed.
Step 3. Now we will create a project in htdocs folder of XAMPP. You will find a few default files which you can delete. Change directory to htdocs folder. Run cd C:\xampp\htdocs.
Step 4. We will use composer to build our new project. So, to do that, run the following command.
We have installed Laravel Composer, and we have also created a project named NinjaApp. Now, we will use the command line and XAMPP to view our application on the local host. Note that it is necessary to first change the directory to your project’s directory.
Run the following commands
cd NinjaApp
php artisan serve
The second command will start the server, and you will get a local host address.
When you visit the given local host, you will find the below-shown page.
This page verifies that laravel is installed and the application is ready to be developed.
