The steps to install the Laravel PHP framework are as follows: 1. Make sure that the system has PHP >= 8.0, Composer and related extensions installed, and can be verified through php -v and composer --version; 2. Use the Composer command composer create-project laravel/laravel your-project-name to create a project. Windows users may require administrator permissions, and domestic users can configure mirror acceleration; 3. Set storage and bootstrap/cache directory permissions, generate .env files and configure database information; 4. Run php artisan serve to start the development server, visit http://127.0.0.1:8000 to verify whether the installation is successful. Follow the above steps and there will generally be no problems.

Installing the Laravel PHP framework is actually not complicated. As long as you know how to use Composer, you can basically do it in a few minutes. Laravel is one of the most popular PHP frameworks at present, providing elegant syntax and rich features for rapid development. Below I will explain how to install it in a few steps and what to pay attention to.

1. Ensure that the system environment meets the requirements

Before you start, you need to confirm that the following components are installed on the local or server environment:

• PHP >= 8.0 (It is recommended to use the latest stable version)
• Composer (PHP's dependency management tool)
• OpenSSL, PDO, Mbstring, Tokenizer, XML, Ctype, JSON, BCMath and other extensions

You can run php -v and composer --version from the command line to see if PHP and Composer are installed.

If Composer is not installed yet, you can download the installer on the official website or use the following command to install the global version:

 curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer

2. Create a Laravel project using Composer

The most recommended way to install Laravel is to use Composer's create-project command. Open the terminal, go to the directory where you want to create the project, and run:

 composer create-project laravel/laravel your-project-name

Here your-project-name can be replaced with your own project name, such as myblog or laravel-app .

After this step, Composer will automatically download and install Laravel's core files and all its dependencies.

Note: If you are using a Windows system, administrator permissions may be required to execute smoothly. In addition, if domestic users feel that the download is slow, they can set up a Composer image first:

 composer config -g repo.packagist composer https://packagist.phpcomposer.com

3. Set permissions and configuration files (optional but important)

After the installation is complete, some details need to be dealt with:

• Storage directory permissions : Make sure storage and bootstrap/cache directories have write permissions, otherwise an error will occur.

   chmod -R 775 storage bootstrap/cache

• Generate application key : Laravel requires the key in the .env file to encrypt the data. If there is no .env file, you can copy .env.example and rename it to .env and run:

   php artisan key:generate

• Database configuration : Open the .env file, find the configuration item starting with DB_* , and fill in your database information, such as user name, password, database name, etc.

4. Run the test server to verify that the installation is successful

Laravel comes with a lightweight development server, which is very suitable for testing whether the installation is successful.

After entering the project directory, run:

 php artisan serve

By default, the service will run on http://127.0.0.1:8000 . Open the browser to access this address and see Laravel's welcome page, it means that the installation has been successful!

Basically these are the operations. The whole process is not complicated, but there are several small things that are easy to ignore, such as permission issues and .env configuration. As long as you do as you say step by step, you will generally not make any mistakes.
