"<p>Symfony is a popular open-source framework for building web applications using the Model-View-Controller (MVC) architectural pattern. In this article, we will walk through the process of setting up a new Symfony 5.4 project.</p> <p>Before we begin, you will need to have PHP and Composer installed on your machine. You can download the latest version of PHP from the official website, and you can download Composer from the official Composer website.</p> <p>Once you have PHP and Composer installed, open a terminal or command prompt and navigate to the directory where you want to create your new Symfony project.</p> <p>To create a new Symfony project, you can use the <code>composer create-project</code> command. This command creates a new project using the latest stable version of Symfony. To specify the version of Symfony, use <code>symfony/website-skeleton</code> with version 5.4.*</p> <pre> <code>composer create-project symfony/website-skeleton:5.4.* my_project </code></pre> <p>The command above will create a new directory called "my_project" in your current directory, and it will install all of the necessary dependencies for a new Symfony project.</p> <p>Once the installation is complete, navigate into the new "my_project" directory, and run the following command to start the built-in web server:</p> <pre> <code>php bin/console server:run </code></pre> <p>This will start the web server and make your new Symfony project accessible at http://localhost:8000</p> <p>You can now start building your application.</p> <p>In addition to the built-in web server, Symfony also supports several other web servers, including Apache and Nginx. If you plan to use one of these web servers in production, you will need to configure it to work with your Symfony application.</p> <p>Next, you might want to configure your database, you can use the <code>.env</code> file to set your database credentials.</p> <pre> <code>DATABASE_URL=mysql://db_user:db_password@127.0.0.1:3306/db_name </code></pre> <p>If you are going to use Doctrine, the next step would be to create entities and define their relationships, You can do this by running the following command</p> <pre> <code>php bin/console make:entity </code></pre> <p>This command will start an interactive process for creating a new entity.</p> <p>You can now start building your application using the Symfony 5.4 framework.</p> <p>It's recommended to also keep your Symfony up to date by running</p> <pre> <code>composer update </code></pre> <p>in case any new security updates or features are available</p> <p>That's it! You now have a new Symfony 5.4 project up and running, and you're ready to start building your application. Keep in mind this is just a basic setup and there are many more things to consider while developing on symfony such as routing, controllers, and templates.</p>"
