In addition to running environment components, PHP developers also need to configure the web server and database to ensure that they work in the correct way. These configurations include adjusting PHP runtime parameters, setting up database connections, etc.

In short, the PHP running environment is a series of components and configurations required on the web server to interpret and execute PHP scripts and interact with databases and other applications to realize the functions and functions of web applications. characteristic. Understanding and mastering the PHP operating environment is very important for PHP developers to help them create high-performance, stable and powerful web applications.
