History and Evolution of PHP
Table of Content:
PHP stands for “PHP: Hypertext Preprocessor” where “Preprocessor” means that changes happen before the HTML page is created. This converts static webpage to dynamic webpage with the capacity to interact with databases. The PHP programming language is commonly used for developing web-based software applications. However, the use of the language is not limited to web development and it can also be used for developing GUI applications. As per netcraft.com in 2013, PHP found application in over 244 million websites.
History and Evolution of PHP
PHP was designed for web development, intended to fill the gap between Server Side Includes (SSI) and Perl. The language’s roots were laid in 1994 through the work of Rasmus Lerdorf who scripted a series of Common Gateway Interface (CGI) binaries in C to maintain his homepage. Gradually, he improved these to include the ability to interact with databases and web forms and named it PHP/FI meaning “Personal Home Page/Forms Interpreter”. The first version of PHP/FI was released in 1995 with syntax, variables and form handling resembling Perl language. The second version PHP/FI 2 was released in 1997.
The team enlarged in 1997 to include Zeev Suraski and Andi Gutmans who re-scripted the parser to form the base of PHP3 and renamed it PHP: Hypertext Preprocessor. The rewriting work continued further and in 1999, it led to the development of Zend Engine which served as an interpreter for PHP language.
Over the years, the updating of the language has continued and the latest version PHP 5.6.4 was released in December 2014.
