This is the age of internet and everything seems to be just a few key strokes away from you. The concept of websites revolutionized the world of internet. Almost all kind of information can be easily found on websites. Now websites has become an important part of the internet world. Not only has it become important for information dissemination, but it has also become a business. You can easily advertise your products all over the world within a few minutes. These days, the websites have advanced much more and act as your live agents all over the globe.

You not only can advertise yourself, the facility provided by static websites with the help of html has now changed and there is dynamic form of sites being created. It means the information given on the web continuously changes and even the web behaves as living person. It can register you, it can give you live music, it can provide the facility to download music, pictures, films, it can even act as a live shopkeeper from where you can buy the products, can exchange money, can pay for everything. We call these pages as dynamic web pages. There are different tools and languages that provide the facility to develop the dynamic web, i.e. ASP, JSP, PHP and many others.

We'll discuss about the PHP (Hypertext Preprocessor). It's a widely used scripting language that was designed for the web development to produce the dynamic WebPages. Programmers embed the PHP code in HTML (Hyper Text Markup Language) code, which is then interpreted by the web server.

PHP was a creation of Rasmus Lerdrof in 1995 and this language is still going through continuous development. Now we will discuss about the history of PHP. A major version of PHP was released on 08-06-1995. It was called officially as (PHP tools) "personal Home page tools". Later on, in 11-01-1997, a new version 2.0 was released by the PHP officials. They considered this version as the simplest and fastest tool for the creation of the dynamic web pages. A 3.0 version was released on 06-06-1998. The developers moved the development from one person to a group of developers.

A version 4.0 was released on 22-05-2000 with many of the subversions also being released in the days after the release of version 4.0. Its further versions 4.1, 4.2, 4.3, 4.4 were released on 10-12-2000, 22-04-2002, 27-12-2002 and 2005 respectively. All these versions are not supported these days. Another version 5.3.2 was released on 04-03-2010 and is being supported even now. A large number of bugs have been fixed in this version.

PHP is a general-purpose scripting language that is particularly appropriate to server-side web development. PHP usually runs on a server and many web servers are supporting the PHP for the deployment. Many rich applications are being developed in PHP. So PHP is plating a vital role in the field of web development. If you want to learn PHP you don't have a need for purchasing any software. Developers of PHP are providing the source code for the users free of cost. So you can easily learn and design the interactive dynamic WebPages.
