Explain in detail the difference between PHP and hltm

PHP and HTML are two completely different technologies, used to create dynamic web pages and static web pages respectively. This article will introduce the differences between PHP and HTML in detail.

1. Definition

HTML (Hyper Text Markup Language) is the basic web development language. HTML uses markup language to create web pages. Due to its simplicity and ease of learning, HTML has been widely used in the web page production process.

PHP (Hypertext Preprocessor) is an object-oriented server-side scripting language that can be used for Web development, dynamic generation of HTML, and many other intended applications. PHP scripts run on the server and send HTML code to the browser. PHP scripts can be freely mixed with HTML markup language to achieve richer and dynamic web page effects.

2. Structure

The structure of HTML is relatively simple. Its main components are the header and the body. The header uses meta and title tags to describe and define the web page, while the body uses tags to define the main content of the web page.

The structure of PHP is relatively complex. It includes not only HTML code, but also server-side script code. The PHP script runs on the server and generates HTML code, which is then sent to the browser and ultimately presented to the user. PHP code can be embedded in HTML code, so dynamic web page effects can be achieved.

3. Use

HTML is widely used in web page production and is favored by beginners because of its simplicity and ease of learning. HTML can be used to create static web pages. It cannot execute server-side script code and cannot respond to user operations and input.

PHP is widely used in web development, especially those web applications that require dynamically generated content. PHP can be integrated with various databases to achieve dynamic data display and processing. PHP can be used to handle various forms and user input, but it requires server support to be used.

4. Function

HTML is mainly used for the layout and typesetting of web pages. It lacks dynamics and interactivity. HTML can only create static web pages and cannot respond to user operations and input.

PHP can be used to dynamically generate web page content, and it can be integrated with the database to achieve dynamic data display and processing. PHP can respond to user operations and inputs, and can handle various forms and user inputs, thereby achieving a rich user experience closer to desktop applications.

5. Summary

HTML is the basic web development language. It is mainly used for the layout and typesetting of web pages. PHP is a server-side scripting language that can be used to dynamically generate HTML and develop various web applications. HTML can only create static web pages, while PHP can make web pages more dynamic, interactive and rich. HTML and PHP together form two essential components in modern web development. Developers can choose to use different technologies according to their needs to create more beautiful and powerful websites.
