The difference between php and it: 1. Php is a computer programming language, while it generally refers to Internet technology; 2. Php is a script language executed on the server side, and it refers to a kind of information technology developed and established on the basis of computer technology.

This article operating environment: Windows7 system, PHP7.1 version, Dell G3 computer.

What's the difference between php and it?

One: PHP (computer programming language)

PHP (PHP: Hypertext Preprocessor), or "hypertext preprocessor", is a scripting language executed on the server side, especially suitable for Web development and can be embedded in HTML. PHP grammar learned C language, absorbed the characteristics of Java and Perl to develop its own characteristic grammar, and continuously improved itself according to their strengths, such as java's object-oriented programming, the main goal of which was to allow developers to quickly write high-quality web websites. PHP supports both object-oriented and process-oriented development and is very flexible in use.

After more than 20 years of development, with the rapid development and improvement of php-cli-related components, PHP has been applied to the research and development of non-Web systems such as TCP/UDP services, high-performance Web, WebSocket services, Internet of things, real-time communications, games, micro services and so on.

According to statistics released by W3Tech on December 6, 2019, the programming language used by PHP on the server side of the WEB website accounts for 78.9% [23]. Of the content management system websites, 58.7% use WordPress (CMS system developed by PHP), which accounts for 25.0% of all websites.

It (Internet technology) generally refers to Internet technology.

Internet technology refers to a kind of information technology developed and established on the basis of computer technology. Internet technology connects different devices through the wide area network of computer networks, speeds up the transmission of information and broadens the access to information, promotes the development of different software applications, and changes people's way of life and learning. The universal application of Internet technology is a symbol of entering the information society.

Internet technology has three meanings, namely, hardware, software and application.

The first layer is hardware, which mainly refers to the host and network communication equipment for data storage, processing and transmission.

The second layer refers to software, including all kinds of software that can be used to collect, store, retrieve, analyze, apply and evaluate information. It includes commercial management software such as ERP (Enterprise Resource Planning), CRM (customer relationship Management) and SCM (supply chain Management), as well as WF (Workflow) management software and DW/DM (data Warehouse and data Mining) software, which are used to strengthen process management.

The third layer refers to application, which refers to the collection, storage, retrieval, analysis, application and evaluation of all kinds of information, including the application of ERP, CRM, SCM and other software to directly assist decision-making, as well as the use of other decision analysis models or technical means such as DW/DM to further improve the quality of analysis and assist decision-makers in decision-making (emphasize that it is only to assist rather than replace people in decision-making).

Some people understand that the Internet technology combines the first two layers into one, which refers to the storage, processing and transmission of information, while the latter is the application of information; others divide the latter two layers into one, which is divided into hard before and soft after. Usually, the third layer has not received enough attention, but in fact, only when the information is effectively applied can the value of IT be brought into full play, and the goal of informatization can be really achieved. Informatization itself is not a goal, it is only a better means to achieve the goal in the current era.

What does Carl's Internet technology mean? He didn't mention it explicitly in that article, but he mentioned the core functions of information technology-data storage, processing and transmission. From the logic of his reasoning, that is, from the construction of infrastructure such as steam engine, railway, Telegraph and telephone, electricity, and so on, Moore's Law is also used to support the development of mainframe and optical fiber.
