How do PHP and Nginx work together?

The way PHP works with Nginx is as follows:

1. The client sends an HTTP request to the Nginx server.
2. After receiving a request, the Nginx server determines whether the URL needs to be processed by PHP.
3. If PHP processing is needed, Nginx will forward the request to the PHP interpreter (such as PHP-FPM).
4. The PHP interpreter parses the PHP code into executable commands, executes them, and generates HTML content.
5. The PHP interpreter will send the generated content back to the Nginx server.
6. The Nginx server will send the retrieved content back to the client.

In summary, Nginx acts as a reverse proxy server, receiving and forwarding HTTP requests. The PHP interpreter is responsible for processing PHP code and generating content. The two communicate through the HTTP protocol, enabling the generation and display of dynamic web pages.
