How Does PHP Work in Web Development?
The basic idea of PHP is to take requests received from users on your website and process them to generate dynamic content. Here are the main steps in which PHP works:
- HTTP Request: When a user accesses a website, their browser sends an HTTP request to the web server.
- Interpreting PHP Code: The server receives the request and identifies files containing PHP code. These files are then interpreted by PHP, and the code is executed to process the request.
- Displaying in the Browser: The resulting web page is sent back to the user’s browser, which displays the dynamically generated content.
