About PHP in brief

Summary PHP PHP is a general-purpose scripting language especially suited to web development. It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1994. PHP code is usually processed on a web server by a PHP interpreter. The standard PHP interpreter, powered by the Zend Engine, is free software released under the PHP License. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge. As of December 2020, 72% of PHP websites use discontinued versions of PHP, i. e. PHP 7. 2 or lower no longer supported by The PHP Development Team; and large additional fraction is on PHP7. 3 that is by now supported for critical security issues only. Over 40% of allPHP websites use version 5. 6 or older, that not even Debian supports. Since 2014, work has gone on to create a formal PHP specification. Since version 7. 0: PHP is no longer under development nor will any security updates be released from PHP 4.5 or 5. In 2008, PHP became the only stable version under development under development. Many high-profile updates from PHP 5 were added in version 3.5, including support for object-oriented programming, the Data Objects extension, and numerous performance enhancements. In July 2004, PHP 5 was released with new features such as improved support for Object Oriented Programming (OOP) and the ability to embed HTML in the code. In August 2008, version 4.

5 became theOnly stable version of PHP 4 became 5.5 became stable under development and added static binding binding and static binding. In June 2008, the PHP Group released a new rewrite of the core of the language, known as PHP 5.0. The new core is now produced by the The PHP Group and is available for download from the company’s website. The language is free to download and install on most operating systems and platforms. It can be used for many programming tasks outside of the web context, such as standalone graphical applications and robotic drone control. It is not intended to be a new programming language, and grew organically, with Lerdorf noting in retrospect: “I have absolutely no idea how to write a programming language I just kept adding the next logical step on the way.” The language was not originally designed, but instead was developed organically. In some cases, the function names were chosen to match the lower-level libraries which PHP waswrapping. The syntax resembled that of Perl, but was simpler, more limited and less consistent. It now stands for the recursive initialism PHP: Hypertext Preprocessor. It originally stood for Personal Home Page, but it now stands as PHP: Hypertext Preprocessor (PHP: hypertext preprocessor – the acronym for the language’s name). It is also used to refer to a number of web-related applications, including Twitter, Facebook, YouTube, and other sites.
