What is the difference between web front-end development and back-end development?
The difference between web front-end development and back-end development is: front-end development is mainly responsible for the front-end display interface that users can see, and back-end development is mainly responsible for logical function modules that are invisible to users. Front-end development and back-end development require different technologies. Front-end development requires mastering technologies such as html, css, and js, while back-end development requires mastering technologies such as php, java, and jsp.
What is Web front-end development?
(Recommended tutorial: html tutorial)
Web front-end, as the name suggests, is used to make the front-end page of the web; That is, in web applications, users can see and touch things. Including the structure of the web page, the visual appearance of the web, and the implementation of interaction at the web level.
What is web backend development?
The Web backend is more responsible for the service technology implementation of the product, including business logic, data storage and processing, message queue processing, etc. And product server interface implementation, including interfaces with the front end, third-party interfaces, internal interfaces of the service system, etc. Back-end development mainly involves interacting with the database to process corresponding business logic.
The difference between web front-end development and back-end development is:
1. Different display methods
Web front-end development mainly focuses on the front-end display interface that users can see.
Web back-end development mainly focuses on logic functions and other modules, which are invisible to users.
2. The technologies used are different

Is PHP front-end or back-end in web development?
Mar 24, 2024 pm 02:18 PM
PHP belongs to the backend in web development. PHP is a server-side scripting language, mainly used to process server-side logic and generate dynamic web content. Compared with front-end technology, PHP is more used for back-end operations such as interacting with databases, processing user requests, and generating page content. Next, specific code examples will be used to illustrate the application of PHP in back-end development. First, let's look at a simple PHP code example for connecting to a database and querying data:
