Laravel is an open source PHP web application framework that can greatly simplify the web application development process. It provides many out-of-the-box tools and technologies, allowing developers to build full-featured, high-quality web applications more quickly and efficiently. But for developers who are new to it, they are still a little confused when it comes to building Laravel programs. In this article, we will introduce you to the basic construction process of Laravel, hoping to help you get started with Laravel.

1. Environment setup

Before we start building the Laravel application, we need to ensure that the environment meets the following two necessary conditions: PHP and Composer.

1.PHP environment setup

We can check whether PHP has been installed by entering the following command in the terminal (macOS and Linux systems) or command prompt (Windows system):

php?-v

If PHP has been installed, the corresponding version number will be displayed. If it is not installed, you need to install PHP. In macOS and Linux systems, you can install it using a package manager like Homebrew or apt-get. In Windows systems, PHP can be installed using WAMP or XAMPP packages.

2.Composer environment setup

Composer is a dependency management tool for PHP. We can check whether Composer is installed by entering the following command in the terminal or command prompt:

composer?-v

If it has been installed, Composer will display the corresponding version number. If it is not installed, we need to follow the instructions on the Composer official website (https://getcomposer.org/download/) to install it.

2. Create a new Laravel project

After completing the environment setup, we can use Composer to create a new Laravel project in the terminal or command prompt:

composer?create-project?--prefer-dist?laravel/laravel?blog

Above In the command, blog is the project name. You can replace it with your own project name in the corresponding position as needed.

3. Add database configuration

Laravel uses SQLite database by default, but if you need to use other database types, you need to configure the database information first. Before developing Laravel applications, we need to change the default SQLiteDatabase to a commonly used relational database such as MySQL or PostgreSQL. Here we take MySQL as an example.

Find the .env file in the root directory of the project. This is Laravel's environment configuration file. Modify the following information:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your_database_name
DB_USERNAME=your_database_username
DB_PASSWORD=your_database_password

Among them, your_database_name is your own database name, your_database_username is the database username, and your_database_password is the database password.

4. Run the Laravel application

After completing the database configuration, we can start the Laravel application through the following command:

php?artisan?serve

The above command will start a local Web server. Run the program. You can access your Laravel application by typing http://localhost:8000 in your browser.

5. Conclusion

In this article, we introduced the basic process of building a Laravel program, from environment construction to Laravel program creation, database configuration, and operation. I hope this article can help everyone get started with Laravel development more quickly and efficiently. For more in-depth application and development scenarios of Laravel, continuous learning and exploration are required in practice.
