What extensions do thinkphp5.0php need?

With the rapid development of the Internet, the PHP programming language has become one of the main choices for developing Web applications. As an efficient, safe, easy-to-use, and flexible PHP development framework, the ThinkPHP framework has strong modularity, scalability, and maintainability. When developing web applications using ThinkPHP, some developers may encounter the need to install extensions. Today we will introduce the extensions required by ThinkPHP 5.0 and their uses.

1. PHP extension
