Laravel is a popular PHP development framework that is widely used in the development of web applications. Laravel 5.5 is its latest version, and to use Laravel 5.5, you first need to meet some environmental requirements. This article will introduce the Laravel 5.5 environment requirements in detail.

1. PHP version

Laravel 5.5 requires PHP 7.0.0 or above to run. It is recommended to use PHP 7.2 or 7.3 version for best performance. If your server is still running PHP 5.x, you need to upgrade it to meet the requirements of Laravel 5.5. You can check the PHP version by running the php -v command.

2. Extensions

Laravel 5.5 requires the following PHP extensions:

• OpenSSL PHP Extension
• PDO PHP Extension
• Mbstring PHP extension
• Tokenizer PHP extension
• XML PHP extension
• Ctype PHP extension
• JSON PHP extension

These extensions usually come with the PHP installation. If you do not have custom compilation options during installation, you do not need to install additional extensions.

3. Database

Laravel 5.5 supports multiple database types, including MySQL, PostgreSQL, SQLite and SQL Server. However, you need to install the corresponding PHP extension when using different databases.

If you are very familiar with a certain database, it is recommended to use that database when using Laravel 5.5. This takes advantage of the database and makes it easier to configure and manage.

4. Web Server

Laravel 5.5 can run on a variety of web servers, including Apache and Nginx. However, you will need to set up your web server to ensure that it can run your Laravel application correctly. For specific settings, please refer to Laravel official documentation.
