![]() ![]() This is an example of custom PHP code for the WordPress content management system. In some cases, the function names were chosen to match the lower-level libraries which PHP was "wrapping", while in some very early versions of PHP the length of the function names was used internally as a hash function, so names were chosen to improve the distribution of hash values. The fact that PHP was not originally designed, but instead was developed organically has led to inconsistent naming of functions and inconsistent ordering of their parameters. Įarly PHP was not intended to be a new programming language, and grew organically, with Lerdorf noting in retrospect: "I don't know how to stop it, there was never any intent to write a programming language I have absolutely no idea how to write a programming language, I just kept adding the next logical step on the way." A development team began to form and, after months of work and beta testing, officially released PHP/FI 2 in November 1997. ![]() Hey, you are using Netscape ! Sorry, that record does not exist Welcome ! You have credits left in your account. The syntax resembled that of Perl, but was simpler, more limited and less consistent. This included Perl-like variables, form handling, and the ability to embed HTML. This release already had the basic functionality that PHP has today. ![]() To accelerate bug reporting and improve the code, Lerdorf initially announced the release of PHP/FI as "Personal Home Page Tools (PHP Tools) version 1.0" on the Usenet discussion group June 8, 1995. PHP/FI could be used to build simple, dynamic web applications. He extended them to work with web forms and to communicate with databases, and called this implementation "Personal Home Page/Forms Interpreter" or PHP/FI. PHP development began in 1994 when Rasmus Lerdorf wrote several Common Gateway Interface (CGI) programs in C, which he used to maintain his personal homepage. Rasmus Lerdorf, who wrote the original Common Gateway Interface (CGI) component, together with Andi Gutmans and Zeev Suraski, who rewrote the parser that formed PHP 3. W3Techs reports that, as of April 2021, "PHP is used by 79.2% of all the websites whose server-side programming language we know." Since 2014, work has gone on to create a formal PHP specification. The PHP language evolved without a written formal specification or standard until 2014, with the original implementation acting as the de facto standard which other implementations aimed to follow. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge. The standard PHP interpreter, powered by the Zend Engine, is free software released under the PHP License. PHP code can also be directly executed from the command line. Additionally, PHP can be used for many programming tasks outside of the web context, such as standalone graphical applications and robotic drone control. Various web template systems, web content management systems, and web frameworks exist which can be employed to orchestrate or facilitate the generation of that response. On a web server, the result of the interpreted and executed PHP code – which may be any type of data, such as generated HTML or binary image data – would form the whole or part of an HTTP response. PHP code is usually processed on a web server by a PHP interpreter implemented as a module, a daemon or as a Common Gateway Interface (CGI) executable. PHP originally stood for Personal Home Page, but it now stands for the recursive initialism PHP: Hypertext Preprocessor. The PHP reference implementation is now produced by The PHP Group. It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1994. ![]() PHP is a general-purpose scripting language especially suited to web development.
