PHP: Hypertext Preprocessor (the name is a recursive acronym A recursive acronym is an abbreviation that refers to itself in the expression for which it stands. The term was first used in print in April 1986) is a widely used, general-purpose scripting language A scripting language, script language or extension language is a programming language that allows control of one or more software applications. "Scripts" are distinct from the core code of the application, which is usually written in a different language, and are often created or at least modified by the end-user. Scripts are often that was originally designed for web development Web development is a broad term for any activity to developing a web site for the World Wide Web or an internet. This can include e-commerce business development, web design, web content development, client-side/server-side scripting, and web server configuration. However, among web professionals, "web development" usually refers only to to produce dynamic web pages A dynamic web page is a hypertext document rendered to a World Wide Web user presenting content that has been customized or actualized for each individual viewing or rendition or that continually updates information as the page is displayed to the user. For this purpose, PHP code is embedded into the HTML HTML, which stands for Hyper Text Markup Language, is the predominant markup language for web pages. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists etc as well as for links, quotes, and other items. It allows images and objects to be embedded and can be used to source document and interpreted by a web server A web server is a computer program that delivers content, such as web pages, using the Hypertext Transfer Protocol. The term web server can also refer to the computer or virtual machine running the program. In large commercial deployments, a server computer running a web server can be rack-mounted in a server rack or cabinet with other servers to with a PHP processor module, which generates the web page A webpage or web page is a document or resource of information that is suitable for the World Wide Web and can be accessed through a web browser and displayed on a computer screen document. As a general-purpose programming language, PHP code is processed by an interpreter application in command-line A command-line interface is a mechanism for interacting with a computer operating system or software by typing commands to perform specific tasks. This text-only interface contrasts with the use of a mouse pointer with a graphical user interface (GUI) to click on options, or menus on a text user interface (TUI) to select options. This method of mode performing desired operating system operations and producing program output on its standard output channel. It may also function as a graphical application. PHP is available as a processor for most modern web servers and as standalone interpreter on most operating systems In computing, an operating system is an interface between hardware and user, which is responsible for the management and coordination of activities and the sharing of the resources of a computer, that acts as a host for computing applications run on the machine. One of the purposes of an operating system is to handle the resource allocation and and computing platforms In computing, a platform describes some sort of hardware architecture or software framework , that allows software to run. Typical platforms include a computer's architecture, operating system, programming languages and related runtime libraries or graphical user interface.
PHP was originally created by Rasmus Lerdorf Rasmus Lerdorf is a Danish-Greenlandic programmer and is most notable as the creator of the PHP programming language. He authored the first two versions. Lerdorf also participated in the development of later versions of PHP led by a group of developers including Jim Winstead (who later created blo.gs), Stig Bakken, Shane Caraveo, Andi Gutmans and in 1995[1] and has been in continuous development ever since. The main implementation of PHP is now produced by The PHP Group and serves as the de facto standard A de facto standard is a custom, convention, product, or system that has achieved a dominant position by public acceptance or market forces . De facto is a Latin phrase meaning "concerning the fact" or "in practice". Other standards may be voluntary or may be de jure ("ordained by law") standards enforced by for PHP as there is no formal specification In computer science, a formal specification is a mathematical description of software or hardware that may be used to develop an implementation. It describes what the system should do, not how the system should do it. Given such a specification, it is possible to use formal verification techniques to demonstrate that a candidate system design is.[3] PHP is free software Free software, software libre or libre software is software that can be used, studied, and modified without restriction, and which can be copied and redistributed in modified or unmodified form either without restriction, or with minimal restrictions only to ensure that further recipients can also do these things and that manufacturers of consumer- released under the PHP License The PHP License is the software license under which the PHP programming language is released. The PHP License is a non-copyleft free software license according to the Free Software Foundation and an open source license according to the the Open Source Initiative. The license is GPL-incompatible due to restrictions on the usage of the term PHP, which is incompatible with the GNU General Public License The GNU General Public License is a widely used free software license, originally written by Richard Stallman for the GNU project (GPL) because restrictions exist regarding the use of the term PHP.[4]
