What is the difference between php and it?

1: PHP (computer programming language)

PHP (PHP: Hypertext Preprocessor) is a "hypertext preprocessor", which is a scripting language executed on the server side. It is especially suitable for Web development and can be embedded in HTML. PHP syntax learned the C language, absorbed the characteristics of multiple languages ​​​​of Java and Perl to develop its own unique syntax, and continued to improve itself based on their strengths, such as Java's object-oriented programming. The main goal of the language was originally created to make Developers quickly write high-quality web sites. 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 can already be applied in TCP/UDP services, high-performance Web, WebSocket services, Internet of Things, real-time communication, System development in non-Web fields such as games and microservices.

According to statistics released by W3Techs on December 6, 2019, PHP’s share of programming languages ​​used on the WEB website server is as high as 78.9% [23] . Among websites with content management systems, 58.7% use WordPress (CMS system developed by PHP), which accounts for 25.0% of all websites.

2: it (Internet technology) generally refers to Internet technology

Internet technology refers to an information technology developed and established based on computer technology. Internet technology connects different devices to each other through the wide area network of computer networks, speeds up the transmission of information and broadens the channels for obtaining information, promotes the development of various software applications, and changes the way people live and learn. The widespread application of Internet technology is a sign of entering the information society.

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

The first layer is hardware, which mainly refers to hosts and network communication equipment for data storage, processing and transmission;

The second layer refers to software, including data collection, storage, Various software for retrieving, analyzing, applying, and evaluating information, including what we usually refer to as ERP (Enterprise Resource Planning), CRM (Customer Relationship Management), SCM (Supply Chain Management) and other commercial management software, as well as software used to enhance WF (workflow) management software for process management, DW/DM (data warehouse and data mining) software for auxiliary analysis, etc.;

The third layer refers to application, which refers to collection, storage, retrieval, analysis, and application , Evaluate and use various information, including the application of ERP, CRM, SCM and other software to directly assist decision-making, and also include the use of other decision-making analysis models or technical means such as DW/DM to further improve the quality of analysis and assist decision-makers in making decisions (emphasis on one point , only assists rather than substitutes for human decision-making).

Some people understand Internet technology by combining the first two layers into one, collectively referring to the storage, processing and transmission of information, while the latter refers to the application of information; others combine the last two layers into one, It is divided into hard at the front and soft at the back. Usually the third layer has not received enough attention, but in fact it is only when information is effectively used that the value of IT can be fully exerted, and the goal of informatization can truly be achieved. Informatization itself is not a goal, it is just a better means to achieve the goal in the current era.

What does Carl’s Internet technology refer to? He did not explicitly mention it in that article, but he mentioned the core functions of information technology-data storage, processing and transmission. Judging from the logic of his reasoning, it was derived from the construction of infrastructure such as steam engines, railways, telegraphs and telephones, and electricity. Moore's Law was also used to support the development of mainframes and optical fibers.
