As it is realized today, PHP is truly the standby to an item named PHP/FI. It was introduced in 1994 by Rasmus Lerdorf, the absolute first exhibition of PHP was a direct arrangement of Common Gateway Interface (CGI) parallels inscribed in the C programming language. Initially utilized for ensuring visits to his internet-based resume, he named the set-up contents " the Individual Home Page Tools," all the more normally referred to as " the PHP Tools." With time, furthermore, functionalities were wanted, and Lerdorf revised his PHP Tools, capable of delivering a lot bigger and more extravagant execution. This model now was capable of information base cooperation; this gives a structured framework through which clients could faster basic powerful web applications. In June of 1995, Lerdorf delivered his source code for the PHP Tools developers' population, allowing engineers and developers worldwide to use it to their best advantage. This additionally allowed and urged clients to give bug fixes in the code and, for the best part, to refine it.

In September 1995, Lerdorf redeveloped PHP, and he dropped the name PHP. Presently alluding to the devices as FI (another way to say " Form Interpreter " ), the new execution incorporated a portion of the fundamental usefulness of PHP as far as we might be concerned today. It had variables that were somewhat similar to Perl, form variables can be automatically distinguished, and HTML imbibed syntax. PHP resembles pearl in syntax but is considerably more limited, easy to use, and unpredictable. Indeed, to imbibe the code into an HTML document, developers have to utilize comments in HTML. However, this strategy was not completely welcomed. FI kept getting popular as a CGI instrument but not exactly as a language.

The language was purposely intended to look alike C in structure, making it a simple reception for developers acquainted with C, Perl, and commonly available languages. Notwithstanding, this started to change the next month; in October 1995, Lerdorf delivered a total revise of the code. Bringing back the original name PHP, it was momentarily named "Personal Home Page Construction Kit," It was only released to boast that it was the most advanced scripting interface present.

In the midst of 1996, the previous code gets a total makeover. Using the names of previous updates, Lerdorf reintroduced PHP - FI. The next-generation implementations genuinely advance PHP from a set-up of instruments into a programming language on its own.

It included pre-installed help for DBM, mSQL, Postgres95 databases, and significantly more. PHP -FI was named version 2.0 in June 1996. A fascinating reality regarding this is that there was just one full version of PHP 2.0. At the point when PHP 2.0 at last escalated from the beta version in November 1997, the latent parsing motor was at that point being remodified. But it did not last very long, but still, the popularity and growth increased amongst the young developers, and in 1997 and 1998, PHP - FI had a whooping community of several thousand developers. And the reports of the 1998 survey stated that around 60000 web domains contain PHP as keywords. Dictating that the host server contains PHP as a base. This was approximately 1% of all present domains over the internet. Notwithstanding these amazing figures, the development of PHP - FI was ill-fated to restrictions; while there were a few minor patrons, it was still basically evolved by a person.

Example PHP - FI Code


PHP 3.0 was the major form that intently looks like PHP as of today. Tracking down PHP - FI 2.0 version still was of no use and lacked highlights they expected to drive an eCommerce application. Andi Gutmans and Zeev Suraski of Tel Aviv, Israel, started one more complete revision of the fundamental parser of PHP in 1997. Moving toward Lerdorf on the web, they examined altered parts of the current execution and their re-development of PHP. With an end goal to work on the parser and turn over increasing upon PHP - FI's current customer base, Andi, Lerdorf, and Zeev decided to team up in the upliftment of a new, autonomous programming language. This new programming language was delivered under another name that eliminated the consequences of restricted personal utilize that the PHP - FI 2.0 name held. It was renamed 'PHP', with the implication turning into a recursive abbreviation - PHP: Hypertext Preprocessor.

Perhaps the greatest strength of PHP 3.0 was its solid extensibility highlights and giving end clients a full-grown connection point for a considerable length of time, conventions, and APIs, the simplicity of expanding the actual language pulled in many engineers who presented an assortment of modules. Other key elements presented in PHP 3.0 included article situated programming support and undeniably more remarkable and reliable language punctuation. Seemingly, this was the way to PHP 3.0's colossal achievement.

In mid-1998, with numerous new designers from around the world joining the work, PHP 3.0 was reported by the new PHP Team as the authority replacement to PHP - FI version 2.0. Dynamic improvement of PHP - FI 2.0, which had everything except stopped as of November of the earlier year, was presently authoritatively finished. After approximately nine months of open public testing, when the declaration of the authority arrival of PHP 3.0 came, it was introduced in the north of 70,000 areas all over the planet. It was not generally restricted to POSIX-agreeable working frameworks. A small portion of the spaces revealing PHP as introduced was facilitated on Windows 95, 98, and Macintosh servers. At its highest point, PHP 3.0 was introduced on around 10% of the running web servers on the Internet present at that time.


By 1998, soon after PHP 3.0 was authoritatively delivered, Andi and Zeev had started chipping away at a modification of PHP's centre. The plan objectives were to develop the execution of intricate applications further and work on the measured quality of PHP's codebase. Such requests were made conceivable by PHP 3.0's new highlights and backing of outsider data sets and APIs. However, PHP 3.0 was not projected to effectively deal with such complex applications.

The new engine, named 'Zend Engine', fulfil these plan objectives excellently and was first presented in mid - 1999. PHP 4.0, in light of this engine, and combined with a wide scope of extra new elements, was authoritatively delivered in May 2000, just about two years after its ancestor. The profoundly better implementation of this adaptation, PHP 4.0, included other important highlights, like, support for some more web servers, HTTP sessions, buffering, safer approaches to taking care of client input, and a few new languages development.


PHP 5 was designed in July 2004. Its core, the Zend Engine version 2.0, is fundamentally controlled by its core, with many new elements.

PHP's advancement community incorporates many designers, just as handfuls others chipping away at PHP-related and supporting undertakings, like PEAR, PECL, and documentation. However, just a gauge in light of insights from earlier years, it is protected to assume PHP is presently introduced on tens or even a huge number of spaces all over the planet.


PHP 6 was introduced in 2005 as a project headed by Andrei Zmievski. He intended to add Unicode support using PHP; he did so by imbibing the ICU library, also known as international components Unicode. But due to a shortage of working staff, the project was at a halt, and for the time being, PHP version 5.3 was introduced in 2009, followed by PHP 5.4 in 2010 with some features of UNICODE.
