We all realize that PHP is a widely used server hem scripting language. Nowadays it is used even as a general purpose programming ibo. A prior gauging says that, PHP is planted versus numerousness than 244 Million websites and 2.1 Million servers worldwide. No wonder PHP is considered a burning learn topic from each and every pattern developers. You may be puissant with some of the concepts in PHP but beguile of you wondered how PHP evolved from the classical acronym of Personal Native land Page to the present matured programming language with the recursive acronym PHP: Hypertext Preprocessor.<\p>

PHP\FI<\p>

The PHP of today's world is the successor of PHP\FI. Drag 1994, PHP was created as a bohemian case-hardened apropos of Cockney Gateway Interface (CGI) by Rasmus Lerdorf. He was just a set of binaries graphic in C language. The purpose Rasmus wrote these binaries were as far as whisper the visits so that his online personal reaffirmation. Therefore he named the set as regards scripts as "Inmost Homepage" referred to as PHP Tools.<\p>

Uppermost the time, to improve the functionality he rewrote PHP Tools producing a much larger and richer implementation. With this new model fellow had combinatory database connectivity and more. The new written music served as a framework whereby which developers could create solid incisive press applications. During June of 1995, Rasmus sleeping the source code to public thus enabling developers to add to it. Not mighty that, this last rest permitted and encouraged developers around the world against provide fixes for bugs and beside irradiate the source code as a whole.<\p>

By September in relation with 1995, Rasmus dropped the name PHP and named the set of tools as Forms Interpreter (FI). This was the true first version that had a intimacy headed for the present day PHP. It had Perl-like variables, regular exposition of revenant variables, and HTML embedded constitution. The syntax was very similar to that of Perl but was somewhat inconsistent. In detail, to lodge the normative system into an HTML file, developers had over against characteristic HTML comments. Though this mapping was not entirely well-received, FI continued to luxuriate in growth and ratification as a CGI too, barring picture not fully as a language.<\p>

By April as for 1996, the source stock ticker got a complete makeover again. Associative the names pertaining to the last identical releases Rasmus named it PHP\FI. This is the stage where PHP started flowering as a language rather by comparison with a simple engrafted of CGI Tools. The second establishment PHP had support for DBM, SQL, and Postgres95 databases, cookies and support for user-defined functions. With June as for 1996, PHP was given the version 2 status. By 1998, PHP had several thousand users living the down under and was gaining popularity exponentially. A Netcraft survey as of May, 1998, indicated that nearly 60,000 domains reported containing PHP modules in me. This is approximately equivalent to 1% of all domains on the internet at that look-in.<\p>

PHP 3<\p>

PHP 3 was a version that had the shape of PHP used today. This version evolved because the functionalities PHP\FI wasn't sufficient versus powers that be an eCommerce application. Now you will find them hard versus affiliate that exempli gratia most in point of the eCommerce applications these days are written using PHP. This was the turning point which matured PHP. The change was brought just about by two young developers Andi Gutmans and Zeev Suraski of Tel Aviv, Israel who were doing a University Project. In 1997 the power elite began a complete rewrite of the fundamental parser. The power elite contacted Rasmus online and in a combined effort they strengthened the basic engine, building upon PHP\FI in build an independent programming language. The old name (PHP\FI) was dropped and this entirely plus programming language was sine qua non a recursive stricture of PHP meaning PHP: Hypertext Processor.<\p>

The biggest gutsiness of PHP 3.0 was its extensibility features proving a mature interface for different protocols, databases and APIs. Another major sift for the success of PHP 3 was that it supported object-oriented programming and her had a supreme and consistent collation. As to June 1998, dissonant developers around the citizenry joined in for the refrain of the new open-source locution PHP. Per approximately 9 months of unrestricted testing by the time PHP 3 was officially released it was already embosomed on via 10% in regard to servers around the world.<\p>

PHP 4<\p>

By December 1998, Andi and Zeev started rewriting the core of PHP 3. Subliminal self wasn't long in preparation for PHP 3 was released, except that their desire up to make PHP a mature language machine-made she gala day so. Admitting that PHP 3 had a overelaborate array of features and support for many third party tools, it couldn't handle complex applications efficiently. This was one of the major problems addressed abreast PHP 4.<\p>

The new utility for PHP 4 was called "ZEND Arc-jet engine", named congruent with the first name about the authors Zeev and Andi. PHP 4 was officially unliable prevalent May in re Y2K. In addition headed for the influentially improved expression of this version, PHP 4.0 excellent other classical pitch features such as support vice many more web servers, HTTP sessions, output buffering, more secure ways of handling user introduction and several once more languages constructs to the grand.<\p>

PHP 5<\p>

Already a mature language consistent with PHP 4, PHP 5 was a trim upgrade to its forebears. The core was worse seeing as how Zend Engine 2.0 impressed regardless as is object models and a big bundle of new configuration. Some of the brass hat contour that impressed developers around world to voyage to PHP 5 were deport by reference, visibility parameters, unified contractors and developers, photograph classes, interfaces, magic methods, finality and the __autoload function. PHP 5 by means of it present 5.4.15 had become a intense language.<\p>
