This article is about the differences between PHP and the web. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

PHP and web differences: 1, PHP is "hypertext preprocessor", is executed on the server side of the script language, and web is the global wide area network, also known as the World Wide Web, it is a distributed graphical information system;2, PHP is suitable for Web development and can be embedded in HTML, and web usually refers to the website server.

Operating environment: Windows 7 system, PHP 7.1 version, Dell G3 computer.

PHP (Computer Programming Language)

PHP (PHP: Hypertext Preprocessor) is a scripting language that executes on the server side, especially for Web development and can be embedded in HTML. PHP syntax learned C language, absorbing Java and Perl features of a number of languages to develop their own characteristics of syntax, and according to their long-term continuous improvement to upgrade themselves, such as java object-oriented programming, the language was originally created to allow developers to quickly write high-quality web sites. PHP supports both object-oriented and process-oriented development and is very flexible to use.

After more than 20 years of development, with the rapid development and perfection of php-cli related components, PHP can be applied to TCP/UDP services, high-performance Web, WebSocket services, Internet of Things, real-time communication, games, microservices and other non-Web systems.

According to statistics released by W3Techs on December 6, 2019, PHP accounts for 78.9% of the programming languages used on the server side of the website. WordPress (PHP CMS) is used by 58.7% of websites with content management systems, which accounts for 25.0% of all websites.

2: The Web

Web is a global wide area network, also known as the World Wide Web, it is a hypertext and HTTP-based, global, dynamic interaction, cross-platform distributed graphical information system.

It is a kind of network service built on Internet. It provides a graphical and easy-to-access intuitive interface for browsers to find and browse information on Internet. The documents and hyperlinks organize the information nodes on Internet into a network structure.

A Web server, usually a website server, is a program that resides on a certain type of computer on the Internet and can provide documents to Web clients such as browsers, and can also place website files for people around the world to browse.

Additional information:

Traditional Web database systems generally realize the connection and application of Web database systems in two ways, one is to provide middleware on the Web server side to connect Web server and database server, the other is to download application programs to the client side and access the database directly on the client side.

Middleware manages the communication between the Web server and database server and provides application services, which can directly call external programs or script code to access the database, so it can provide dynamic HTML pages related to the database, or execute user queries and format the query results into HTML pages.
