PHP
PHP is a general-purpose scripting language geared towards web development. It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1993 and released in 1995. The PHP reference implementation is now produced by the PHP Group. PHP was originally an abbreviation of ''Personal Home Page'', but it now stands for the recursive backronym ''PHP: Hypertext Preprocessor''. PHP code is usually processed on a web server by a PHP interpreter implemented as a module, a daemon or a Common Gateway Interface (CGI) executable. On a web server, the result of the interpreted and executed PHP codewhich may be any type of data, such as generated HTML or binary image datawould form the whole or part of an HTTP response. Various web template systems, web content management systems, and web frameworks exist that can be employed to orchestrate or facilitate the generation of that response. Additionally, PHP can be used for many programming tasks outside the web context, such as s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PeachPie
PeachPie is an open-source PHP language compiler and runtime for the .NET Framework and .NET. It is built on top of the Microsoft Roslyn compiler platform and is based on the first-generation Phalanger project. PeachPie compiles source code written in PHP to CIL byte-code. PeachPie takes advantage of the JIT compiler component of the .NET Framework in order to handle the beginning of the compilation process. Its purpose is not to generate or optimize native code, but rather to compile PHP scripts into .NET assemblies containing CIL code and meta-data. In July 2017, the project became a member of the .NET Foundation. Origins PeachPie's architecture is similar to the Phalanger project, which had originally started as coursework at the Charles University in Prague, Czechia. It was implemented on Microsoft's .NET compiler platform called Roslyn, utilizing the Roslyn API. Since 2016, the Czech company iolevel has been leading the development of PeachPie. PeachPie has sever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HHVM
HipHop Virtual Machine (HHVM) is an Open-source software, open-source virtual machine based on Just-in-time compilation, just-in-time (JIT) compilation that serves as an execution engine for the Hack (programming language), Hack programming language. By using the principle of JIT compilation, Hack code is first transformed into intermediate HipHop bytecode (HHBC), which is then dynamically translated into x86-64 machine code, optimized, and natively executed. This contrasts with PHP's usual Interpreted language, interpreted execution, in which the Zend Engine transforms PHP source code into opcodes that serve as a form of bytecode, and executes the opcodes directly on the Zend Engine's virtual CPU. HHVM is developed by Meta Platforms, Meta, with the project's source code hosted on GitHub; it is licensed under the terms of the PHP License and Zend License. Overview HHVM was created as the successor to the HipHop for PHP (HPHPc) PHP execution engine, which is a PHP-to-C++ trans ...

Zend Engine License
The ''PHP License'' is the open-source license under which the PHP scripting language is released. The PHP License is designed to encourage widespread adoption of the source code. Redistribution is permitted in source or binary form with or without modifications, with some caveats. Version 3 of PHP used a dual license—PHP 3's source is available under either the PHP License or the GNU General Public License (GPL). This practice was discontinued as of PHP 4, with PHP's developers citing the restrictions on reuse associated with the GPL's copyleft enforcement as being the reason for dropping it. The Zend Engine, the core of the PHP interpreter, is separately licensed under the similar Zend Engine License, which contains similar naming restrictions to the PHP license (applying to the names "Zend" and "Zend Engine"), and a clause requiring advertising materials to mention its use. Criticism The PHP License is an open source license according to the Open Source Initiative, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zend Technologies
Zend, formerly Zend Technologies, is a Minneapolis, Minnesota-based software company. The company's products, which include Zend Studio, assist software developers with developing, deploying, and managing PHP-based web applications. The company was founded in 1999, and it was acquired in 2019 as part of Perforce's acquisition of Zend's parent, Rogue Wave Software. History Zend Technologies was founded by Andi Gutmans and Zeev Suraski who, along with other Israeli graduates of the Technion, the Israel Institute of technology, further developed PHP after its initial creation by Rasmus Lerdorf. The name Zend is a combination of Suraski's and Gutmans' forenames, Zeev and Andi. In 1997, Gutmans and Suraski rewrote the parser of PHP-FI, originally written by Lerdorf, resulting in PHP 3. In 1998 they redesigned that parser completely and named it the Zend Engine. PHP 4 is based on the first version of the Zend Engine. In 1999, their company Zend Technologies was formally established an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zend Engine
The Zend Engine is a compiler and runtime environment for the PHP scripting language and consists of the Zend Virtual Machine, which is composed of the Zend Compiler and the Zend Executor, that compiles and executes the PHP code. It was originally developed by Andi Gutmans and Zeev Suraski while they were students at the Technion – Israel Institute of Technology. They later founded a company called Zend Technologies in Ramat Gan, Israel. The name Zend is a combination of their forenames, Zeev and Andi. The first version of the Zend Engine appeared in 1999 in PHP version 4. It was written in C as a highly optimized modular back-end, which for the first time could be used in applications outside of PHP. The Zend Engine provides memory and resource management, and other standard services for the PHP language. Its performance, reliability and extensibility played a significant role in PHP's increasing popularity. This was followed by ''Zend Engine 2'' at the heart of PHP 5 ...

Hack (programming Language)
Hack is a programming language for the HipHop Virtual Machine (HHVM), created by Meta Platforms, Meta (formerly Facebook) as a dialect of PHP. The language implementation is free and open-source software, licensed under an MIT License. Hack allows use of both dynamic typing and static typing. This kind of a type system is called gradual typing, which is also implemented in other programming languages such as ActionScript. Hack's type system allows types to be specified for function (programming), function argument (computer programming), arguments, function return values, and class properties; however, types of local variables are always inferred and cannot be specified. History Hack was introduced on March 20, 2014. Before the announcement of the new language, Facebook had already implemented the code and tested it on a large part of its web site. Features Hack is designed to interoperate seamlessly with PHP, which is a widely used open-source scripting language that has a fo ...

Rasmus Lerdorf
Rasmus Lerdorf (; born 22 November 1968) is a Danish-Canadian programmer. He co-authored and inspired the PHP scripting language, authoring the first two versions of the language and participating in the development of later versions led by a group of developers including Jim Winstead (who later created blo.gs), Stig Bakken, Shane Caraveo, Andi Gutmans, and Zeev Suraski. He continues to contribute to the project. Early life and education Lerdorf was born on Disko Island in Greenland and moved to Denmark in his early years. Lerdorf's family moved to Canada from Denmark in 1980, and later moved to King City, Ontario in 1983. He graduated from King City Secondary School in 1988, and in 1993 he graduated from the University of Waterloo with a Bachelor of Applied Science in Systems Design Engineering.

C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

Functional Programming
In computer science, functional programming is a programming paradigm where programs are constructed by Function application, applying and Function composition (computer science), composing Function (computer science), functions. It is a declarative programming paradigm in which function definitions are Tree (data structure), trees of Expression (computer science), expressions that map Value (computer science), values to other values, rather than a sequence of Imperative programming, imperative Statement (computer science), statements which update the State (computer science), running state of the program. In functional programming, functions are treated as first-class citizens, meaning that they can be bound to names (including local Identifier (computer languages), identifiers), passed as Parameter (computer programming), arguments, and Return value, returned from other functions, just as any other data type can. This allows programs to be written in a Declarative programming, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
